Serving Data From 2 Hard Disks
I have a server with 2 hard drives, say drive A and drive B. Right now all my files, database and data is on drive A, and drive B is empty. Since I have another drive available, I want to split the load between the two drives. I'm ok with having the web pages and the database on one drive. I mostly want to just have the data (I have about 500GB of data) split between the two drives. Note that I want to avoid duplicating the data. I want to have each file on either drive A XOR drive B.
Should I map a separate subdomain to drive B and then use that subdomain to serve the half of the data thats there? Is there something I can do with hard/soft links on the server so that even though the data is on 2 drives, users still use the same url to access data on either drive? Any other options?

Mail-in Hard Disks
anyone know any managed dedicated server provider who we can mail our hard disks to? We have a small pipe to the Internet and this is the only avenue we've thought of. Or perhaps another solution that we haven't thought of?

Hard Disk Went Broken And I Need To Recovery Data
My server (Fedora Core V and Plesk 8) hard disk broke 2 days ago and my bakckup tar.gz is too old. Datacenter (fdcservers.net) tried to put old harddisk as slave but server is not recognising the old drive. Datacenter say that can not do anything more. My question: Is there any software or company that can recovery my harddisk data? My last 6 months work is gone now.

Hard Drive Failure, Recover Data
I just recently had a hard drive failure that produced the following error root@re:/# mount /dev/hda3 /mnt mount: wrong fs type, bad option, bad superblock on /dev/hda3, missing codepage or other error In some cases useful info is found in syslog - try dmesg | tail or so ide: failed opcode was: unknown end_request: I/O error, dev hda, sector 4410069 Buffer I/O error on device hda3, logical block 8259 hda: drive_cmd: status=0x51 { DriveReady SeekComplete Error } hda: drive_cmd: error=0x04 { DriveStatusError } ide: failed opcode was: 0xb0 The host is going to mount this HD on the same machine after adding a new hard drive and fresh install... Does anyone have any recommendations for how I can go about recovering data? Specifically mysql databases?

Best Servers Disks
Hardisk brands all had their ups and downs over time. So almost all brands made sometime bad drive models that failed (yes, even IBM) I just finished reading an article that currently for servers it seems Seagate is the best (currently). Some say Western, some say Maxtor, I heard everything. It seems nobody agrees or there isnt one that actually has the lowest failure rates. It would be nice to hear from real experience on servers scenarios (not office, or desktop). The article also said Hitachi was one of the worst and my eyes just popped out. I found reviews of people here that said Hitachi where the bests. So to conclude it seems everybody has their own preference. It would be nice to hear some Datacenters or people with tons of servers. I suppose recovery centers and datacenters probably have the best stats on which disks are failing the most.

IIS Just Stopped Serving..
I have been hosting a site for the past number of weeks on IIS on Server 2003..I have a no-ip a/c which is working fine along with port forwarding on my router.. The other day I restarted my server for something but now I cant seem to access my site from across the internet and according down for everyone or just me (website) it is down. I can, however, access the site using domain name from within my lan. I'm not too hot on server 2003 or IIS. What can I do to debug/diagnose the problem?

Mega Database Disks
How do you handle your mega space requirements for your high-use databases? Do any of you work with storage in the terabytes? If so, what kind of hardware and setup do you use? Do you just have many commodity servers with maybe 100GB or so in each, or do you have some kind of shared RAID array set up? Or some kind of SAN? Keep in mind I'm not talking about network storage (i.e. slow, personal use, file server) but rather high-speed intensive high-read/high-write database requirements. What are the options for implementing such a solution? What types of products fit such requirements? Could you comment on what things to look for when purchasing such a set of products?

Replace Disks With Little Downtime
I colo a 1U machine with 2-36gig drives. They're not in RAID, and I have it set to rsync backups to a remote machine on a regular schedule. I have another remote machine functioning as a secondary DNS. Neither of these 2 are on a large upstream pipe. I just bought 2-147gig drives that I'd like to replace the 36g's with. How does this sound for a scenario to accomplish this with little downtime (pre-pardon my noob'ish ways): 1. Do a complete rsync of the filesystem to my remote machine as well as sync the mysql db's (to 1 remote drive). 2. Pop that single rsync'd drive into an external enclosure. 3. Travel to datacenter, once there, plug external drive into laptop and start up a VM that boots off of that drive. 4. Sync again so external drive has the most up-to-date data. 5. Change over IP's from colo to VM on laptop. 6. Shutdown and swap out drives in colo'd box with the new ones. 7. Setup new drives as RAID 1, install OS, then rsync filesystem over from laptop to new drives in colo'd box. 8. Change back IP's. What am I missing, or is there an easier way without a 2nd colo/dedicated server? Currently, the colo'd machine is using about 1.3Mbit/sec outbound and it's running a low load.

Servint - Serving Porn On My Sites
What is up with servint? I have domains and a vps through them. The vps is now serving up porn on all the sites. When I call servint they say I don't own the name but a whois shows i DO INDEED own the name for another year and it is registered to me and they are the registrar!!! The portal user/pass suddenly stopped working so I can't even put in a support ticket All I get is a message machine ... does anyone know if servint staff ever come on this board. It has probably been hacked but it is pretty disturbing when they say I don't own the domain but it is CLEAR THAT I do own it.

Speed Up Serving Large Files
I'm working on a web site which will basically be a flash games portal. I have a dedicated server running Apache 2 on a 100mbit dedicated line but my download speed for large files (flash files of over 5mbs) is really slow. I am thinking this is because of Apache but I don't know much about this. I've read that I should change for a lighter http server for serving static files. The way my server is set up is I have 2 virtual machines running, one doing the PHP processing and the other serving static files, both running Apache, so if I have to change HTTP server for the static files it would be very easy. Although I am not sure if this is necessary or if I can tune Apache to push files faster than this.

Static File Serving - Performance
I'm planning to setup a server ONLY for hosting of static binary files varying from few KB to few MB in size. I've seen some of the litespeedtech performance benchmarks, which you can find here: [url] From the "small static file" benchmark chart, i can see that IIS6 beats lighttpd in this test. So i'm wondering does the IIS6 really have better performance at file hosting than lighttpd. Actually it does not matter which operating system i will be using at this server, since i will use it only for file serving. With lots of concurrent connections. Possibly thousands of connections. I need some feedbacks on this, so i can decide, IIS or lighttpd. Few more bucks for win2k3 won't be an issue here, if it's performance is better than lighttpd for this kind of use.

10 Second Lag Serving Static HTML
this isn't my server, so I don't have a lot of information about it, other than it's a Linux/Apache Dedicated server at EV1. (cPanel/WHM) There are other sites on the server, and they are running fine. One site has a terrible lag. It takes about 10 seconds to serve up a static HTML file.. Now, it's not like the server is slow. It's like this: You request a small HTML file. The site sits and thinks about it for about 10 seconds, and then after that everything processes quickly. The forum on the site is the same way. Everything you click on works fine and loads quickly after that initial delay passes. Is there a common configuration problem that might be causing this? If you want to see this phenomenon, here are a few test files: [url] [url] [url] [url]

Apache Serving Blank Pages
I am having this issue with a new box where Apache at random serves blank pages and won't serve anything but until it's restarted. I see no errors in /var/log/messages either to show why this is happening. It's not all pages either just several various ones. I know it's not a programming issue either because the only thing the server is running is one instance of vBulletin. I look at top during this and CPU and RAM usage are very low. The only fix to get Apache to serve the pages is to restart it. Anyone have any clues on what it could be? I set my php.ini memory limit to a gig (I have 16 gigs in the sever)

Do Hosts Stagger RAID Disks
if I order a RAID from a host, can I be confident that they're not going to put two of the same make, model and order in there? Or at least run one of the disks for a significant time before using inserting into the RAID?

Linux Hot Swapping Disks
I have a server with SATA- Hot Swap disks. I can do this, and swap out a disk, and re-partition the new one, however the running Linux kernel hangs on to the old partition table in memory. So even though the disk is not in use, and has been re-partitioned, I still need to reboot to get the kernel to see the new partitions, and use them. Is there any way around this? How to force kernel to re-read disk partitions on non-system disks?

Hot Swap Disks And CentOS
Up to now we've been using CentOS with SCSI/SATA disk shich weren't "hot swap", and now we're upgrading to a Dell PowerEdge 1950 revision III with SAS hot swap disks on a PERC RAID 6i (new model of raid controller from Dell). OF COURSE, Dell ONLY supports Windows (and Red Hat at the very most on the Linux world) so we were told by a Microsoft Tech that to be able to extract a disk and replace with another it had to be done via software. (The software powers the disk down and then you replace it) Does anyone use CentOS with hot swap SAS disks? Do you use any special software to monitor the disks and/or replace them?

Firmware Update For WDxxxxYS Disks.
Since purchasing 16-disk arrray NAS server 4-5 months ago, 5 disks have crashed so far. They are all WD4000YS. They're all "Raid Edition" which supposed to last longer than typical drives. It has been puzzling me until now. It turns out that "Data Lifeguard" feature was confusing the RAID controller to believe that the disk was dead, hence the "failed" disk. AFAIK, Western Digital released firmware update on 01/09/07 that's supposed to fix this. [url]p_faqid=1493&p_created=1168299631&p_sid=vfEX7qri&p_accessibility=0&p_redirect=&p_lva=&p_sp=cF9zcmNoPTEmcF9zb3J0X2J5PSZwX2dyaWRzb3J0PSZwX3J vd19jbnQ9MiZwX3Byb2RzPTAmcF9jYXRzPTAmcF9wdj0mcF9jdj0mcF9zZWFyY2hfdHlwZT1hbnN3ZXJzLnNlYXJjaF9mbmwmcF9wYWdlPTEmcF9zZWFyY2hfdGV4dD1XRDQwMDBZUw**&p_li=&p_ topview=1 So, if you have WDxxxxYS on your pre-production server, pull them out for a firmware update first! For me, I can only swap "hot-spare" out for a firmware update. For other disks, I'll just have to wait for them to "drop" out of the array first. I cannot take this server offline at all. Any suggestions?

Hot Swap Disks + CentOS
We're about to buy a Dell Poweredge 1950 with hot swap disks in a raid 1 configuration (might even think about other raid combinations). We will be installing Centos 5 (never tried it - normally use Centos 4) + control panel The question is: what happens when a disk fails? How do we find out?(Apart from looking at the server) Any software notices? Once noticed, what is the standard procedure to replace the disk? (Remember they are "hot swap") Do you just pull one out and replace it? Surely you have to rebuild the array...

Serving & Playing Breeze FIles
Having trouble hosting Macromedia Breeze files on a brand new dedicated 2003 NT box. Anything I need to adjust? When someone visits the URL, it loads the presentation main screen, but it's supposed to auto-play several movies and it won't. It works fine locally and on 2 unix servers I tested it on, but not the new NT box. The weird thing is, if I remote desktop to that server, I can't play that presentation locally or server thru the linux boxes. I figured it was an extensions thing, but like I said the intro still does appear, and if I go to Adobe.com and play a new "Adobe Presenter" presentation - it works fine.

Preferred Operating System For Web Serving
I have been online since 95 and I've got a lot of information I could help others with regarding web development and interface design. One thing I'm terrible at is System Administration, but I'm getting better and my first step is to pick a reliable operating system for both the webservers and the database servers. Would anyone be willing to answer the following questions or point me to a thread that already discusses these? A little background, our site has 200k members, 30k active and is growing by about 5k a week. We still run MySQL 4.0.27 on the DB servers and they are running FC2. The webservers are Apache 1.3.37 and PHP 4.4.2 running FC2 and FC4 as well. My questions 1. What OS would you prefer to upgrade to for the web servers? and a "few" reasons why? 2. What OS would you prefer to upgrade to for the database servers? and a "few" reasons why?

Problem Serving Gzipped Static Content
I'm trying to serve as much gzipped content as possible on my web site. I will gzip dynamic pages on the fly using PHP, and I plan to gzip static content just one time, not to use much CPU, and serve css.gz, .js.gz files, etc... So, I uploaded a test.html file and a .css file that changes the color of the text to red. I gzipped the css file: %gzip style.css I also uploaded an .htaccess file with this content: RewriteEngine on RewriteBase /gzip/ RewriteCond %{HTTP_ACCEPT_ENCODING} gzip RewriteRule ^(([^.]+.)+)css$ /$1css.gz For now I'm not going to include any gunzipped style sheet, just to make sure my browser picks the gzipped style sheet. I also uploaded a phpinfo.php file to make sure I have mod_gzip. So, here's the list of files I have: - .htaccess - style.css.gz - test.html - phpinfo.php But when I open the test.html file: [url] the style sheet isn't applied. If I upload a regular style.css file, it works fine. It seems the Rewrite rules aren't taken into account. Do you know how I could server the gzipped style sheet instead?

15K Rpm SAS Disks Greater Than 146 GB
Currently we're using HP servers with 4 hot-swap bays that hold 3.5" Seagate Cheetah 15K RPM SAS disks, which we can get in 300, 450, and 600 GB flavors. I'm looking at the HP DL380/385 models which use 2.5" SAS disks. About the only decent 15K RPM SAS disk I've found in 2.5" form is the Seagate Savvio, but it doesn't come any larger than 146 GB. Anyone know of another enterprise-class SAS disk that has all of the following attributes: 2.5", 15K RPM, SAS, and at least 300 GB? (Please, no 10K RPM or SATA recommendations like the WD Velociraptor. I won't consider anything that's not 15K RPM SAS.)

Moving My Install From Single Disk To Raid 1 Disks
If you want a quick run down as to WHY I want to do this, read here Basically, my ISP could not get my server running stable on a simple raid 1 (or raid 5) so what it came down to was having them install my system on a single disk. I don't exactly like this, main reason being, if the system (or HDD) crashes, I'll end up with another several hours of down time... So here is my proposal: Please Note: This will have to be accomplished on a live System (full backups!) over ssh as I don't trust my ISP to do things right as described in my post above. Current Setup: CentOS 5.3 x86_64 Dual Xeon 5410 16GB RAM 4x 750GB HDDs /boot - /dev/sda1 - 512MB (real 471MB) ext3 / - /dev/sda2 - 50GB (real 46GB) ext3 /home - /dev/sda3 - remaining space (real 642GB) ext3 swap - /dev/sdb1 - 32GB /backup - /dev/sdb2 - remaining space (real 659GB) ext3 /dev/md0 - /dev/sdc + /dev/sdd - raid 1 (NOTE: uses entire disk, no partitions!) Proposed Solution: Code: vgcreate -s 64M vg0 /dev/md0 lvcreate -L 512M -n lvboot vg0 lvcreate -L 50G -n lvroot vg0 lvcreate -L 5G -n lvtmp vg0 lvcreate --extent 100%FREE -n lvhome vg0 mkfs -t ext3 -m 1 /dev/vg0/lvboot mkfs -t ext3 -m 1 /dev/vg0/lvroot mkfs -t ext3 -m 1 /dev/vg0/lvtmp mkfs -t ext3 -m 1 /dev/vg0/lvhome Now, I'd like to 'init 1' at this stage but I can't, so I won't (possible solutions?? Possible to umount the / partition??) Assuming I'd have to do this on a fully live system, I'd disable all services that I can Code: /etc/init.d/sendmail stop /etc/init.d/postfix stop /etc/init.d/saslauthd stop /etc/init.d/httpd stop /etc/init.d/mysql stop /etc/init.d/courier-authlib stop /etc/init.d/courier-imap stop /etc/init.d/amavisd stop /etc/init.d/clamd stop /etc/init.d/pure-ftpd stop /etc/init.d/fail2ban stop /etc/init.d/syslogd stop Then we copy all of our data from the single partitions to the raid disks Code: mkdir /mnt/newroot mkdir /mnt/newroot/boot mkdir /mnt/newroot/tmp mkdir /mnt/newroot/home Code: mount /dev/vg0/lvboot /mnt/newroot/boot mount /dev/vg0/lvroot /mnt/newroot/root mount /dev/vg0/lvtmp /mnt/newroot/tmp mount /dev/vg0/lvhome /mnt/newroot/home (I think I covered everything) Code: umount -l /dev/sda1 (/boot) umount -l /dev/sda3 (/home) cp -dpRx /* /mnt/newroot/ mount /dev/sda1 /boot cp -dpRx /boot/* /mnt/newroot/boot/ mount /dev/sda3 /home cp -dpRx /home/* /mnt/newroot/home/ Once we have everything copied, update /etc/fstab and /etc/mtab to reflect the changes we made: vi /etc/fstab Code: LABEL=/home /home ext3 defaults 0 3 LABEL=/ / ext3 defaults,usrquota,grpquota 1 1 LABEL=/boot /boot ext3 defaults 1 2 tmpfs /dev/shm tmpfs defaults 0 0 devpts /dev/pts devpts gid=5,mode=620 0 0 sysfs /sys sysfs defaults 0 0 proc /proc proc defaults 0 0 LABEL=SWAP-sdb1 swap swap defaults 0 0 To Code: /dev/vg0/lvhome /home ext3 defaults 0 3 /dev/vg0/lvroot / ext3 defaults,usrquota,grpquota 1 1 /dev/vg0/lvboot /boot ext3 defaults 1 2 tmpfs /dev/shm tmpfs defaults 0 0 devpts /dev/pts devpts gid=5,mode=620 0 0 sysfs /sys sysfs defaults 0 0 proc /proc proc defaults 0 0 LABEL=SWAP-sdb1 swap swap defaults 0 0 Moving on, we make a fail safe in the event this doesn't work out: vi /boot/grub/menu.lst find Code: default=0 add after Code: fallback=1 Then we find (in the same file): Code: title CentOS (2.6.18-164.el5) root (hd1,0) kernel /vmlinuz-2.6.18-164.el5 ro root=/dev/vg0/vgroot initrd /initrd-2.6.18-164.el5.img Add before: Code: title CentOS (2.6.18-164.el5) root (hd3,0) kernel /vmlinuz-2.6.18-164.el5 ro root=/dev/sda2 initrd /initrd-2.6.18-164.el5.img Where (hd3,0) is /dev/sdc. If the system fails to boot to the raid then it'll auto boot to the single disk (/dev/sda) then update my ramdisk: mv /boot/initrd-`uname -r`.img /boot/initrd-`uname -r`.img_bak mkinitrd /boot/initrd-`uname -r`.img `uname -r` And now to set up grub... Code: grub > root (hd0,0) > setup (hd0) we should see something like this: Checking if "/boot/grub/stage1" exists... no Checking if "/grub/stage1" exists... yes Checking if "/grub/stage2" exists... yes Checking if "/grub/e2fs_stage1_5" exists... yes Running "embed /grub/e2fs_stage1_5 (hd0)"... 15 sectors are embedded. succeeded Running "install /grub/stage1 (hd0) (hd0)1+15 p (hd0,0)/grub/stage2 /grub/grub.conf"... succeeded Done. Code: > root (hd3,0) > setup (hd3) Again, we should see something like this: Checking if "/boot/grub/stage1" exists... no Checking if "/grub/stage1" exists... yes Checking if "/grub/stage2" exists... yes Checking if "/grub/e2fs_stage1_5" exists... yes Running "embed /grub/e2fs_stage1_5 (hd1)"... 15 sectors are embedded. succeeded Running "install /grub/stage1 (hd1) (hd1)1+15 p (hd1,0)/grub/stage2 /grub/grub.conf"... succeeded Done.

What Type Of Server And Os, Etc For Just File Serving- Small Files Like Under 10kb
I have a website that just serves small files, under 10kb most of them. I just need a server that lets me ftp the file to it, set up subdomains and domains for one website. Don't need to manage mysql or anything. Not even php. Just serve files. A good fast OS? Something like lighttpd? Ioono? I'm currently doing 600gb of bandwidth per month. I'm expecting to do about 1000gb by the end of the year. Would a small server like a pentium 4 be able to handle just serving files?

An Otherwise Great Performing Server Now Delays Prior To Serving PHP/mysql
One of my dedicateds (Fedora 7 / apache 1.39 / php5 mysql5) has been running flawlessly but now has a strange ~4-5 second delay when serving up PHP/mysql pages such as Wordpress. I say delay because it appears to think about it for several seconds, then when the page finally begins the refresh process, everything serves up lightning fast. Latency is low, direct file downloads are faster than ever. ModSecurity is running, and accounts for about 1 second of that delay (tested with it on and off), but the other 3-4 seconds is a mystery.

TWO Data Recovery Companies Failed To Recover My Data
I have 100+ sites on this hard drive, and one site in particular that meant the world to me. My host sent the drive to Gillware first, but they failed saying that the file system was so severely damaged that they could not recover anything. Then shortly after, my host sent it to DriveSavers, a very well-known company, but they also FAILED. I'm extremely depressed because of this. Please don't post if you're going to say "make sure you do backups next time" because I've heard it 504329504395 times now, and while I do realize my mistake, saying that does NOT help me. I am willing to spend ALOT to get my sites back. I still have hope. Are there any other companies out there BETTER than DriveSavers? Assuming that you'd still have hope even after two companies failed, where you would you go or what would you do?

The hard drive is now being shipped to a more well known company, Drive Savers - [url]and I'm guessing that this is the last hope, because the more the drive gets tampered with, the more chance of permanent data loss. So yeah.. I was just wondering what you think? If the file system is so severely damaged, do you think it STILL can be recovered?

How Hard Is Unmanaged Really

I am pretty smart though I have a lot of experience with cpanel, and I am not worried about getting my feet wet. This is the system I want: Celeron 1.7 GHz 1 GB RAM 80 GB HD 1500 GB Bandwidth cPanel / WHm Full root access How much time would it take to keep the thing running? How do you monitor the server? How do you know when software updates, and patches are available? Can all of the software needed be found for free? What kind of problems would I encounter, and would this be way over my head?

Hard Drives For VPS
I'm building a couple of VPS host servers for a client. Each server have to host 20 VPS and each server will be 4 cores with 32GB of ram. So CPU and ram should be just fine, my interrogatioon now is hard drives. The company owns the machines, but not the drives yet. I searched a lot on your forums but found nothing relating on VPS. I'm basicly a DBA IRL, so I have experience in hardrives when it comes to databases, but it's completely different for VPS. According to my boss, each VPS will run a LAMP solution (having a separeted DB cluster is out of question for some reason). First, raid1 is indeed a must. There is room for 2x 3.5 drives. I might be able to change the backplane for 4x2.5, but i'm not sure... I've came to several solutions: 2x SATA 7.2k => comes to about 140$ 2x SATA 10k (velociraptor) => comes to about 500$ 2x SAS 10k with PCIe controller => comes to about 850$ 2x SAS 15k with PCIe controller=> comes to about 1000$ They need at least 300GB storage. But my problem is that the servers do not have SAS onboard so I need a controller and in my case the cheapest solution is best. But I'm not sure that SATA 7.2k will hold the charge of 20 complete VPS. Does it worth it to go with SAS anyway or SATA should be just fine? With SATA better use plain old sata 7.2k or 10k drives? That's a lot of text for not much: What is best for VPS: SATA 7.2k, SATA 10k or SAS 10k?

I just received: [cPanel smartcheck] Possible Hard Drive Failure Soon ATA Error Count: 1512 (device log contains only the most recent five errors) Error 1512 occurred at disk power-on lifetime: 11736 hours (489 days + 0 hours) Error 1511 occurred at disk power-on lifetime: 11736 hours (489 days + 0 hours) Error 1510 occurred at disk power-on lifetime: 11736 hours (489 days + 0 hours) Error 1509 occurred at disk power-on lifetime: 11736 hours (489 days + 0 hours) Error 1508 occurred at disk power-on lifetime: 11736 hours (489 days + 0 hours) ----END /dev/sda-- What do you advice me to do? ask the DC to change the Hard Drive or wait till damaged?

Hard Drive Arrangement
Hard drive arrangement I have a terminal server with a bunch of applications on it, among which is a database driven app. There have been complaints that access to the db is sluggish. right now the server is on just one 7.2k drive. I am guessing its a hard drive bottleneck because memory and cpu usage seems okay. I have a few ideas. Please tell me which of these you would recommend. 1. Upgrade entire server to raid 10 system. 2. Upgrade the entire server to a 5-disk RAID 5 system. 3. Create two raid 1 setups. One for the OS and regular apps, the second one to host the DB. 4. Create a raid 1 setup for the OS and regular apps, and a RAID 5 setup for the DB. Ideally I would like to see improved read/write speeds on both regular files/apps and on the database. The RAID 10 system was what I was leaning towards at first because the stripping increases throughput, but then I realized I may see better performance by keeping the regular files and the DB on independent setups so that OS and file read/writes won't affect the DB read/writes.

Linux Hard Drives
On my centos webserver I currently am using a 250gb ide drive. I just bought 2 Western Digital Raptor WD1500ADFD 150GB 10,000 RPM 16MB hard drives. And now I am wondering what kind of setup I should have? Should I have the 250gb hd as a backup drive now and have the two raptors in a raid 0 array. What would be the best configuration?

Dead Hard Drive
I have never had a hard drive fail on me, i dont think the I/O on my servers would ever warrant it but im looking to ask people that have had a hard drive die one them the following: 1. Were you ever cautious before your hard drive failure or did you lose data and if you did lose data, did it make you buck up your ideas (i.e do you now have a solid backup plan or do you still play maverick) 2. If you have had a hard drive failure, has it made you, do you think, overly-cautious? 3. Has a hard-drive failure ever swayed you towards the more expensive raptor drives? and if so, why?

Site Being Attacked Hard
I'm Tech admin at Fagex.net This site has always been prone for attacks on it's servers. At the moment theres been a new owner and so things are not settled back down yet, How ever people are still atacking the site. The hosting as far as i am aware has no software/hardware firewall i have tould the onwer but has not taken my advice. This morning i woke up to find it was being attacked, so i went stright to SSH and started blocking them etc. I was looking around for free Anti DOs tools and came across, [url] Seems good, I've only just installed so still need to see the effects. I also added a block in to htacess which has Quote: <ifmodule mod_limitipconn.c> <cocation /> Maxconnperip 3 NoIPlimit image/* </location> </ifmodule> The server is a dedicated VPS, and the owner has two sites on which both are forums. What can i do to protect the sites? What can i do to prevent them? What can i do to stop them.

Have A Hard Time With New Server
Week ago I decided to rent another dedicated box , install CentOS 5 64Bit and use LiteSpeed as a web server. What seemed to be trivial at start became nightmare later. I was unable to compile PHP 5 with --with-litespeed and --with-curl directives. If I removed one of them it was ok but together it didn't work. Tried to search forums but nothing helped, so I decided to go back to Centos 5 32bit and try there. It compiled OK. So I'm in trouble now. I wanted to have server with 64bit OS + LiteSpeed because of its speed, system resources consumption and good DOS protection. I asked several questions about advantages of 64bit over 32bit OS and the most important thing was how much issues can I expect on 64bit OS (libraries availability). Almost every reply said that it's without issues to go with 64bit OS. My experiences say it's not as easy as I expected. I didn't find any good protection against DOS for Apache so far, mod_evasive doesn't work as I expected. What do you recommend ? Should I stay with apache on Centos 64bit + apache with everything installed via yum (should work OK) or go with CentOS 5 32bit + LiteSpeed there ? LiteSpeed I'm talking about is Enterprise edition.
