The server is displaying these errors when I tried to do an FSCK:
Bad inode IO
ext3-fs error (device(8,3)) IO Failure
I am having a new primary installed and old primary set as 2nd drive. I need to recover the cpanel domain accounts from this 2nd drive after I mount it with the method below:
mkdir /backup
mount /dev/sdb1 /backup
However, how do I actually recover these accounts in an automated process via whm? I've done this before with the same matter (corrupt primary drive, mount as 2nd, etc) but cannot exactly remember the proper steps.
I have a dedicated box and I started getting Input/output errors today.
I tried: # fsck fsck 1.40-WIP (14-Nov-2006) e2fsck 1.40-WIP (14-Nov-2006) /dev/hda2: recovering journal fsck.ext3: unable to set superblock flags on /dev/hda2
then I tried: # fsck -a -t ext3 /dev/hda2 fsck 1.40-WIP (14-Nov-2006) /dev/hda2: recovering journal fsck.ext3: unable to set superblock flags on /dev/hda2
My data is backed up, so was going to ask for a reimage, but is this an indication of bad hardware? Should I ask for a replacement drive? Is there anything else I should try on my own before going to the host?
O/S was corrupt so I had to do a reload on a new drive. I'm trying to mount original drive (already connected as 2nd) but it is not showing up in df -h

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.
The problem is that my hd is failed. Hoster setup new server, also installed the secondary drive but not mounted. So need advice how can i get my data off it?
Since my linux server is out of disk space, I just use cifs to mount some drives from the windows server for people to download files (usually 100-200mb/file).
But I found the performance is not good. For example, I need to wait for a long time before the download process begin. Also, it seems the load average of the server becomes high too.
Is there any suggestion? Should I mount the windows drives through cifs? Or should I change to another server which allow me to add more local harddisks? How about if I mount drives in other linux machine, will the performance better?
1- i did Os Reload with new Hard drive for "home" 2- data "backups" drive lost
3- replaced the old home drive as "/old drive"
4- " /old drive " is now the secondry drive in my server and it has the all sites usres and evry thing
5- what i need , to trasfer, copy this sites from " /old drive " to "home"
but data center said
The /olddrive/home directory contains the contents that were previously in the /home directory. You can copy files from this directory to any other directory on your server.
The command to copy files in the UNIX environment is the "cp" command.
The user directories in /olddrive/home directory contain the web page files for the users. However, simply copying the contents over will not recreate the users or domain entries in DNS/httpd. If you wish these back you will need to recreate them manually or restore them from backups.
I just purchased a brand new 10K 150GB drive. How can I take an exact copy of my current drive and transfer everything over to the new drive? I think I need to create a snapshop, or mirror it somehow.
What software will do this? I was told trueimage, but its very pricy, is there anything else?
I have a Win2K3 server which has 2 hard drives. I was considering backup options and I thought that I might try mirroring Drive A ==> Drive B. I would think that, then, if Drive A has a hardware failure, I could simply switch Drive B into the Primary slot (A) and the server would continue to hum along as nothing has happened. This would reduce the downtime, hopefully.
I have 3 questions.
1. Is this idea practical (will it work)? 2. What is a good software program to use fto handle the mirroring? 3. Any considerations, warnings, technical advice in regard to this method?
I've got another server comming online shortly which will be used for shared hosting. A Q9550, 8 GB DDRs, 2 1 TB SATA drives in RAID 1. I know everyone has different opinions and reasons for their partitioning decisions, so I wanted to get a feel on how you would partition the drives durring setup, and why you would do it the way you do.
I need your opinion on the best drive configuration for my Dell poweredge 2850 dual 3.0.
I have 6 x 72gb scsi 10k hds, and perc4 raid in server. My os will be Cent os with 4 gigs of ram installed. I want to try to make this server as redundant as possible.
Offsite backup is also in plans. I’m going to use this server for a few sites (5 - 10) that are db driven, and host small video clips as Dolphin Smart Community. Server will be colocated. Please let me know if missed something .
im assembling my server now....waiting on the 90degree connectors. It is as follows:
SUPERMICRO CSE-512L-260B Black 14" Mini 1U Server Case ASUS M2N-MX SE Plus AM2+/AM2 NVIDIA GeForce 6100 Micro ATX AMD Motherboard AMD Athlon 64 X2 4200+ Brisbane 2.2GHz Socket AM2 65W Dual-Core Processor Dynatron A48G 70mm 2 Ball CPU Cooler - Retail 2gb ddr2 6400 ram Seagate 500gb 7200.11 32mb hdd WD 37gb raptor 10k rpm
the wd drive was lying around the house so i figured id add it since i had an extra slot and figured the speed wouldnt hurt.
My question is....how should i partition the drives.? I have 500+gb of space on 2 hard drives. I plan on using centos 5.1 and am downloading the iso now.
Now iam useing 320Gig SATA harddrive as my primary hard drive,i dont use 2rd harddrive,iam haveing pure download site,in TOP command 4.5%wa is this bit high? or can i add 2rd harddisk and move some data to there to reduce wa,but my load of the server is fine or any way to reduce wa?
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 use the second hard drive as backup drive. Today as normal i check the backup directory and try to use ls command. I got this warning [root@xxxxxx backup]# ls
I want to start selling vps to customers but don't want to over load my existing drive/ server would it be beneficial to sell vps off a second drive so im keeping my shared hosting separate from the vps hosting
My server has 2 drives,one is backup drive. The backup drive seem to be failing so i decide to remove it. However when i remove it,the system can not boot. ANyone got this issue?
This is a little samba guide from my own experiences of how to map a network drive under windows 2000 to a Linux server. I am not technical expert and this guide is the result from my trail and error.
What's Samba?
Samba allows Linux computers to share files and printers across a network connection. By using its SMB protocol, your Linux box can appear in Windows Network Neighborhood or My Network Places just like any other windows machine. You can share files this way, as well as printers. By using samba on my home network, for example, my Windows machines have access to a printer directly hooked up to my Linux box, and my Linux box has access to a printer directly hooked up to one of my Windows machines. In addition, everyone can access everyone else's shared files. You can see how samba can be very useful if you have a network of both Windows as well as Linux machines.
My OSs
Windows 2000 RHEL 3 (Redhat Enterprise Linus)
My goal
Map a network drive to Linux servers, so that I can access the Linux files under windows 2000.
Installation
Most Linux should have Samba already installed. But if it hasn't install, you can find at in http://rpmfind.net or using up2date command "up2date -i samba". You can also get it at http://www.samba.org
Then you can install it by tying the following Command:
Install:
rpm -i samba.rpm
Upgrade:
rpm -U samba.rpm
Configuration
Samba conf file is located at /etc/samba/smb.conf, allows you to specify which resources on the Linux machine you wish to share and who they can be accessed by.
Samba provide a full version conf if it's fresh install. But most of the times, we don't really need all of these options. So I provide my own conf here, which is rather simple, but it makes things work.
[Downloads] comment = Downloads path = /path_to_your_sharefolder browseable = yes writable = yes public = yes read only = no
[homes] comment = My Home Directory browseable = yes writable = yes public = yes read only = no
[printers] path = /var/spool/samba public = yes guest ok = yes printable = yes browseable = yes writable = yes read only = no
Just replace workgroup to your windows workgroup name, your_windows_machine_IP and /path_to_your_sharefolder. If you don't need printers sharing, you don't need to have printer section.
Setup Samba Users
Since we're using user level security, we need to setup samba users. This can be easily done by using Webmin. You can go to Server --> Samba --> Convert Unix users to Samba users, you can just covert all your existing Linux users and set them password under the icon "Edit Samba users and passwords" later.
If you don't use webmin, you can also type the following command:
Replace username with each of your user's usernames. You will then be prompted to enter a password for this user account.
Samba Service
Now, it's time to start your samba server:
service smb start service smb stop service smb restart
Once the computer is restarted or shutdown, the samba service won't start up again in next boot up. I use webmin to make it startup at boot time.
Windows 2000 Configuration
1. Under windows 2000, you can got to windows explorer --> Tools --> map a network drive 2. select drive letter 3. enter the path (e.g. your_server_ipDownloads) 4. click connect using different user name 5. enter your samba usernaem and password that you just set 6. You can connect to your Linux machine now!
This method work for me. If there is any correction or improvements, please let me know.
I'm a little familiar with Linux, but I need help setting up a second drive that is in the server I'm leasing from Layered Technologies. It's a self-managed server so they won't even TELL me how to do it.
I need to format the drive and mount it as /backup so I can setup WHM/Cpanel to use it for backups.
What commands do I need to type to format the drive with the right kind of partition and mount it as /backup?

one of my servers has 2x250gb hard drives in hardware RAID 0 using a 3ware controller, but ive now got the following error message 3 times prior to 3 server crashes, my server supplier beleves it one of the drives failing (i have backups on a non raid drive so rthats fine) but i suspect the controller, whats everyone else think...

What do you advice me to do? ask the DC to change the Hard Drive or wait till damaged?
