Clone Centos Failing Hard Drive
Mar 2, 2008
Is it possible to clone centos 4.6.x + cpanel 11 hard drive to brand new disk with same capacity? just like we clone hard drives in windows with noton ghost ?.
I have a server with failing hard drive (smart errors) and drive must be replaced soon but i feel lazy to restore everything from backup hard drive and was thinking it will be smart to just copy mirror of primary hard drive from original hard drive to knew one. Is this possible?
I do have 2 backup copies, so don't worry about that .
Btw, i found this link which says its possible but i am not sure. Please suggest.

I just purchased a 500GB ATA hard drive (meant to get SATA but must have misordered, but I don't think it makes that much difference) to replace a 80GB SATA hard drive on a Windows Server 2003 server. There are two partitions on the 80GB drive, and rather than add the new HD as a third partition, I would like to clone the data on the 80GB drive to the 500GB drive, then increase the partition sizes and remove the 80GB completely. Is there a specific method or software I can use to accomplish this?

I had a smart error emailed to me by the server, so I had Savvis do a hard drive test on my server. They told me my main drive has some bad blocks and is failing. I have a new drive in the tower as a slave already. I went into WHM and clicked in list accounts, the change partition button for a smaller account. That worked moving it from /home to /home2. However when I tried it with a larger account, it seemed to time out. I have all the clients moved accept one, who has a site with about 14 gigs of data.
I think the command would be: mv /home/admin /home2/admin
Is this correct, or is there a better way to do this?
Also if I move it in SSH, will WHM list accounts auto update itself, or will I need to do something for that as well?

so my provider setup my HDD's wrong (i believe).
Filesystem Size Used Avail Use% Mounted on
/dev/sda2 9.7G 5.7G 3.6G 62% /
/dev/sda5 215G 608M 204G 1% /var
/dev/sda1 99M 16M 78M 17% /boot
tmpfs 1013M 0 1013M 0% /dev/shm
/usr/tmpDSK 485M 14M 447M 3% /tmp
the problem is that I have /dev/sda5 mounted to var. I want cPanel to use this HDD as the main storage for the /home directory. How do I make cPanel use this hdd for storage?

Just got this server setup, getting some smart errors. Here's a copy of the trouble ticket I posted to the host, they said "If you read through the documentation for smartd you will find that from the results you pasted, your hard disk passed every test. We can give you another hard disk if you want but we will have to charge you 3 credits for the reinstall of the operating system." I could be wrong, maybe everything's fine, but the fact that there are unreadable sectors reported has me a little worried.

I am running a Fedora box with cPanel...
The hard drive has a capacity of 36 gigs and there's currently 18 GIGs of data on it.
When I do "df -h", it indicates that / has 85% of it's capacity in use. When I run "df -hi" it shows that / has 58% of it's inodes in use.
Is there anything I can do to increase /'s capacity? Can I free up some inodes? All that / contains are folders.

What do you advice me to do? ask the DC to change the Hard Drive or wait till damaged?
I already have a weekly external Backup.

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.

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?

the max HDD allowed iin servers is 8 HDDs only ( depend the type of proceesor ) and it be impossible to make each user in a seperated HDD
but i have a good idea :
mounting a virtual HDDs or something like NAS / SAN / eVault / iSCSI ... etc on the home dir of user ( example : /home/user )

I am going to mount my new hard drive to /home/user/public_html but I have a question before I do so. If I upload stuff to /home/user/public_html will it go to my new hard drive that I just mounted there or will it still go in the old hard drive?
The reason why I want to mount it there is because my other hard drive ran out of space, and I would like to continue this user account's space without having to move this user.

From your experiences, which manufacturer has been the most reliable for you? What kind of life expectancy can I expect from a new hard drive in a server environment? Also, what kind of quality/life can I expect from refurbished drives?
Thanks in advance.
By the way, I'm specifically looking at 10,000RPM SCSI drives. Both U-160 and U-320.

I'm currently hosted on a VPS server with Galaxy Solutions, but just last night I was informed of a hard drive failure.
This morning they said the DC couldn't recover the data, and now they are trying to recover the data themselves. Right now I'm assuming that if the DC can't recover it, then there isn't much of a chance of it being recovered at all.
I've put in countless hours and dedicated so much of my time to my sites, something which certainly cannot be compensated for. I would like to exhaust any possible way to recover the data.
Can anyone recommend what I should do in a situation like this? Would it be advisable to consult a data recovery specialist? It would be great if you could also recommend one.
The cost doesn't matter. I'm extremely frustrated, annoyed, and confused because of all this. Just like that, all my work is gone.
I did have backups, but they were on the same server.

what others are using in their servers when it comes to hard drive preferred manufacturer.
We use to only use Seagate but in some recent servers switched to Western Digital Caviar Black Drives (1TB) and experienced 1 failure after 30 days. Not that this makes us think that these are bad drives as we have also had failures with Seagate as well but would really like to know if there any difference in the reliability between manufactures?

if typically you were to add an additional (third) hard drive (SATA) to a server, would it add any additional string on the CPU?
Assume that there is no extra disk usage - meaning that static image and html files off disk two are simply moved to disk 3.

I have my backup disks here because my server got hacked and we didn't like how liquidweb made the things. So we ask them to ship us the disk. They ran photorec and they got lots of .gz files from it. All accounts I would say. But 50% of them the .tar.gz files came corrupt. And is lefting all the big accounts and until now I haven't seen any corrupted file that came with MySQL. And I think MySQL is most important to all clients.

I would really like to know which hard drive brand you have had the best success with in regards to server hard drive reliability. Is it Seagate or Western Digital? Or is it one of the other brands? Please vote. This poll is specifically regarding SATA2 hard drive experiences in servers. Please do not factor in SCSI hard drives.

This week I reached the pinnacle of all time greatest screw ups I've ever done with a web server in five years. During a routine upgrade, my server crashed and basically burned to the point that the technicians at Burst/Nocster felt it would be in my best interest to clear the server out and do a fresh restore.
Fortunately, I had the majorty of files and designs I've done on a safe backup. Unfortunately, the mysql database I had was not so fresh and recent. In there lies my big problem on an issue I really have not seen much information about.
We all know of the mysqldump command that can be used to backup databases and save a .sql file on the server. Its quick, easy, and relatively painless. The problem I have run into is
mysqldump --opt -u nqforum_braduser -p nqforum_nodqdb > /home/nqcom/backup.sql
This would be the command I'd use on my normal mysql dump. However, all of my files and past server information has been installed as a slave hard drive temporarily until I can gather everything I need. Therefore, the command above won't work because it is looking for this mysql database & user that does not exist on the new server. I currently have the slave hard drive path stored at
/mnt/olddrive/
So for example, to get to the website that would have that particular database
/mnt/olddrive/home/nqforum/
So my question for those who know anything about slave hard drives and mysql, how can I get a simple current backup of this database saved to a location, then of course once it is saved as a .sql file somewhere, I can simply run a mysql restore command in SSH to bring it back.

I am trying out all sorts of new drives and raid card adapters because I am finding the 3ware's I have been faithfully using to really suck lately.
We are testing them against areca and adaptec (although I really hate areca from prior bad experience)...
We are using bonnie right now... of course we plan to play around with xen, a couple of domains, prime95, some dd's and then run bonnie too... kind of a stress test.

With the recent zone.net outage I'm thinking of moving to a new VPS.
I noticed that ServInt and other have relatively low storage compared to wiredtree who offers double the storage for the same price.
As both have gotten good reviews, is there a qualitative difference in the storage being used?
