file system creation

i have recently added three hdd to my server (300gb x 3) and created RAID on the same and upon rebooting the server we can see the new partition as

/dev/cciss/c0d1 doesnt contain a valid parition table

i then did

mkfs -ext3 /dev/cciss/c0d1 and mount -t ext3 /dev/cciss/c0d1 /u02

added this in fstab as

label=/u02         /u02     ext3     defauls    1 2

now upon rebooting it says some error

asking to press ctrl d for maintenance and other optin was to repair file system 1
when i selected repair filesystem 1 it again went to repair filesystem 2 .3 4 etc


how to proceed

the error was unable to resolev the label /u02

how can i remove the added entry and make proper entry for that /u02

You need to create a mount point (directory into which the file system will be mounted). Usually those are in the /mnt folder. So go to that folder, then use mkdir to create the u02 folder. After that edit your fstab file again and change the entry from /u02 to /mnt/u02

The boot menu should have a recovery mode or similar entry, that way you should should be able to log in. If that doesn't help use a LiveCD to boot the system with, and then try editing the entry.

shall i try with the bootable linux cd which i have , i think i need to press rescue option

rindiCommented:
Yes, probably. It depends a little on the Distro. If the Bootable CD has a GUI it should be no problem. If it is a pure install CD it is more difficult. Otherwise a very good one is PartedMagic:

What distro are you on, RedHat? CentOS? Scientific? Or something completely different?

it is oel 4.5

i have only the install CD. how can i try with that.

rindiCommented:
I don't use that distro so I'm not sure. I would probably go with the PartedMagic LiveCD.

The system should boot without issue into single user mode.
When you hit Carl-d and get to the shell, you could use e2label /dev/cciss/c0d1 /u02
And that should resolve the issue going forward or edit /etc/fstab and replace the label=/u02 with /dev/cciss/c0d1.

Oops, you should enter the root password to get the shell access, set the label and then hit ctrl-d to resume booting
Or modify the /etc/fstab replacing the label ref with the disk as outlined above.

I've not see in my self, so it is not clear to me which file system issue exists on the system.
Could you try booting the system in single user mode
During the boot up splash, interrupt it and add single to the end of the line and boot the system

Once the system boots you should be able to either label the raided volume as u02 or adjust the fstab to use the raw device reference /dev/cciss/c0d1

You can also run fsck to the various volumes.
Do you have oracle database ocsf or asm filesystems to which the error might refer?
