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?
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?
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?
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
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?
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?
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.)
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.
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]
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?
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.
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?
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...
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.
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.
what I want to do, have a "node" somewhere serve media (static) files from a central server, but cache the static files the first time they are hit, so subsequent requests to the "node" don't require getting the file from the central server.
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.
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.
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?
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)
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.
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?
