Replace Larger HD For Raid 5

Jul 21, 2009

i have a msi server with three seagate HD,

and use seagate ST336607LC to do raid5.

the raid card is adaptec 2200S,

it is installed with centos with cpanel.

today,the websites shows 500 internal error and i asked the DC reboot,

minutes later,the websites run well.

but minutes later,it down again,and i ssh to reboot,

minutes,it shows file system problem,it seems readonly?...in my memory.

and i ask the DC to reboot again,

and i still can not login,and the DC staff tell me it shows with "operation system not found"...

and i go to DC,

it shows there is no logical drives... and operation system not found.

and i try to use ctrl+a to access raid control panel,

it shows there is no raid setting....

and i try to verify the hds in raid control panel,

it shows my 3rd hd has defect and ask if want to assign new block,

at begining,i chose no,it still can not load the os.

and then i chose yes to reassign the block and passing the verify,

but it still can not load the os.

i can not get any ST336607LC now,

i want to ask can i use larger HD to replace the 3rd hd?

if yes,after replacing and booting,

should i reset the raid configuation?

250GB Or Larger Drives

Mar 24, 2009

Anybody know the best place to get a really cheap server with at least 250GB drives? I'm assuming most providers offer HDD's of that size on relatively cheap systems now if we're just looking at SATA.

The machine doesn't need to be anything special, I don't need a ton of bandwidth.

Basically this will be an extra backup machine to pull backups from servers instead of my usual "pushing" of backup data.

So to clarify, I'm looking for a simple machine pretty much anywhere with some drive space! VPS just won't cut it because the drivespace they provide is too expensive (yes, I understand they have nice drive setups though).

RAID etc is not needed, I'm not running anything mission critical but would like to have more locations in place to hold backups for me. WHT worries me alot

Configuring MySQL/Apache To Run A Larger Website More Efficiently

May 12, 2007

I'm running a comic site on a dedicated linux box that has weekly releases. When a new release comes out I'll typically get 4000-5000 unique hits an hour. The problems started when I set up a MySQL download logging system, that would query and display the file names when the user loads the site, and update +1 when they download a comic. Yesterday after a release, the site became very slow to access, and after about 20 seconds you'd connect and be able to browse freely at nice speeds but if you went idle you'd have to wait about 20 seconds to connect again. The other domains on the server were running fine, and I could access my whm fine as well, the server load was 0.10 or lower.

I'm assuming there's a max connection limit somewhere either on the mysql or apache side that's restricting the site from handling the load it's getting. I've poked around google and researched it a bit but couldn't really find much. I don't have an enormous amount of time to invest in this because it's just a hobby so I'd appreciate any help one of you could offer!

Hardware RAID: Is Motherboard RAID As Good As A Dedicated PCI-E Card

Mar 24, 2008

Is Motherboard RAID as good as a dedicated PCI-E card? I am guessing a dedicated card is the best option, though costs more.

We are looking at buying a barebones server from Supermicro. It features an onboard RAID controller which supports RAID 0, 1, 5 & 10 - but for some strange reason it will only support RAID 5 if you use Windows. Here is a link to the page detailing the RAID features.

[url]

We are going to be running Linux, CentOS 5.1, so we will only have the choice of RAID 0, 1 or 10. This isn't an issue, as having RAID 10 on 4x SAS (15k) drives will be fine for speed and stability. What is an issue is would this RAID controller be as fast or reliable compared to a dedicated PCI-E card? If it can only use RAID 5 in windows, does that suggest this controller is too reliant on software? It would be a nightmare to suffer downtime and data loss because the controller couldn't hack it during a drive failure, or one day it decided to bugger up the array when rebooting.

So that leads me to looking at this card, this looks very good for what we need. Are adaptec a reliable brand? I've seen it advertised for 200, which is a good price.

[url]

This card features RAID 5 and 6, would RAID 6 be better than RAID 10 for redundancy, or is it too slow to bother with? Also it seems to have a battery module available for it, what does this achieve? Cos surely if the power dies the hard drives and motherboard can't run off this little battery, or does it just help the controller stay alive long enough with some hard drive information in its memory if the power goes out during a rebuild?

Any Experiences With Software-Raid 5 Vs Hardware-Raid 5? (e.g. Hetzner EQ9)

Sep 17, 2009

I could try the Software-RAID 5 of the EQ9 Server of Hetzner.

Does anyone here has experiences, how fast a hardware raid 5 compared against the software-Raid 5 is?

The i7-975 should have enough power to compute the redundnacy on the fly, so there would be a minimal impact on performance. But I have no idea.

I want to run the server under ubuntu 8.04 LTS x64.

On it a vitualisation like VMware the IO-Load could get really high.

Whats The Best For Server With SATA Raid 1 And SCSI Raid 10

Jan 14, 2008

So I've just got a server with 2xSATA raid 1 (OS, cpanel and everything in here) and 4xSCSI raid 10 (clean).

Which one do you guys think will give the best performance:

1. Move mysql only to 4xSCSI raid 10
2. Move mysql and home folder to 4xSCSI raid 10

How To Setup Software RAID-10 On Linux With /boot On RAID-1

Jul 8, 2007

I am in a somewhat complicated situation... I wanted to order a custom server with hardware 3Ware RAID controller but after over a month of waiting I was told the HW RAID controller, as well as any other 3Ware controller they tried, does not work with the motherboard used in the server from Fujitsu-Siemens and that they simply got a reply from FS that the controller is not certified to work with their motherboard.

So although I'd prefer a HW raid, I am forced to either choose a different webhost or setup a software RAID. The problem is, I haven't done that before and am somewhat moderately...scared

I have read a lot of the info about SW RAID on Linux that I could find through Google but there are some questions unanswered still. So I thought that perhaps some of the more knowledgeable WHT members could help me with this problem...

The server specs will be:

Core2Duo E6600 (2.4Ghz), 2GB RAM, 6-8x* 250GB SATA II HDDs, CentOS 4.4 or SuSe, DirectAdmin

* I prefer 8 HDDs (or actually 9) over 6 but I am not sure if their server chassis can hold that many HDDs, I am awaiting answer from them. They don't have any other drives beside the 250GB ones so I am limited to those.

The preferred SW RAID setup is to have everything in RAID 10, except for the /boot partition which has to be on RAID-1 or no RAID I believe, plus one drive as hot spare (that would be the 9th drive). I am quite sure they will not do the setup for me but will give me access to KVM over IP and a Linux image preinstalled on the first HDD so that I'll have a functional system that needs to be upgraded to RAID-10.

How do I do that? The big problem I see is that LILO or GRUB can't boot from a software RAID-5/10 so I will have to mount the /boot partition elsewhere. It's probably terribly simple...if you have done it before which I have not. I have read some articles on how to setup a RAID-5/10 with mdadm (e.g. [url] ) but they usually do not talk about how to setup the boot partition. Should it be setup as a small sized (100-200MB) RAID-1 partition spread over all of the drives in the otherwise RAID-10 array?

What about swap? Should I create a 4-8GB (I plan to upgrade the server RAM to 4GB in near future) RAID-1 swap partition on each of the disks or swap to a file on the main RAID-10 partitions. The second sounds simpler but what about performance? Is swapping to a file on RAID-10 array a bad idea, performance wise?

Is it possible to grow a RAID-10 array in a way similar to growing a RAID-5 array with mdadm (using two extra drives instead of one of course)? mdadm doesn't actually even mention RAID-10 despite it does support it without having to create RAID-0 on top of RAID-1 pairs if the support is in kernel, from what I know.

Replace Disks With Little Downtime

Feb 12, 2008

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.

Find & Replace Of Text For Security...

Jul 25, 2007

My old VPS was hacked and an iframe html string was added to just about all the files on the server.

I've since then identified the vulnerability and moved to a new host and want to copy the accounts over but wanted to know if there was an easy way to search all the files for this html code and delete it?

For example, search all files for <iframe etc etc> and delete it?

I know this is probably rather simple...but I have no idea how to do it.

Worth Having RAID 1 If Raid Arrays Break

Feb 25, 2009

How often do RAID arrays break? Is it worth having RAID if a servers hard drive goes down? I was thinking it may just be a better option to just have a backup drive mounted to my system and in the even of a system failure just pop in a new hard drive, reload the OS, and then reload all my backups?

RAID 5 Vs RAID 10 In Shared Hosting Server

Oct 22, 2009

I am in the process of restructuring the infrastructure on our servers. I am thinking of using either RAID 5 (1 hot spare) vs RAID 10 as my 1U server has 4 HDD tray.

RAID 5 would have better capacity but RAID 10 has better overall performance. Which one do you guys go for a shared hosting server?

Turn Non Raid Into Raid On Live Server

Is it possible to turn a non raided setup into Linux software raid, while it is live, and if it's the OS drive? Can you even software raid the OS drive remotely? I've been thinking about doing it for the redundancy (and possible slight performance boost for reads, but doing it more for redundancy). I'm using CentOS.

SSH Or Program How To File Replace Lots Of Files

I have anywhere between 80,000 - 90,000 webpages that have a single code into this. Unfortunately at the time the web developer I used didn't use PHP includes. So each .html file has the code in it.

I want a way so I can do a single command either a program or an SSH command can find the syntax in the files and replace it will code I have. Its just a single line of code that is basically for an adsense code, so the pub-blahblahblah etc..

Does anyone know of a SSH command I can use, or a program that will find and replace without manually opening up each file? 80k - 90k of opening files then find/replace will take forever!
