My RAID is error


Hi,
I don't know why my RAID has problems . I can't access it.
When Linux started, It required root password. I typed the password , then I use command:

# fsck -y /dev/ida/c1d0p1

e2fsck 1.32 (09-Nov-2002)
Couldn't find ext2 superblock, trying backup blocks...
fsck.ext3: Invalid argument while checking ext3 journal for /export/home0

-

Because My RAID is mounted on /export/home0. Please tell me the way to fix this problem .
My RAID is hardware RAID : Compaq. RAID level 5

/ex/port/home0 is surely just an empty directory... no wonder it can't check it... it's just a directory. your raid device would usually be /dev/md0, that's what you should be fscking.

Oh no
My raw disk of RAID is /dev/ida/c1d0p1 . It used to be mounted on /export/home0. But now it has error and fsck can't check it .

# fsck -y /dev/ida/c1d0p1

e2fsck 1.32 (09-Nov-2002)
Couldn't find ext2 superblock, trying backup blocks...
fsck.ext3: Invalid argument while checking ext3 journal for /export/home0

I think it has bad superblocks . So I used:

# mount -t ext2 -o sb=32768 /dev/ida/c1d0p1 /export/home0
mount: wrong fs type, bad option, bad superblock on /dev/ida/c1d0p1,
or too many mounted file systems

#mount -t ext3 -o errors=continue /dev/ida/c1d0p1 /export/home0
mount: wrong fs type, bad option, bad superblock on /dev/ida/c1d0p1,
or too many mounted file systems

# mke2fs -n /dev/ida/c1d0p1
mke2fs 1.32 (09-Nov-2002)
Filesystem label=

Block size=4096 (log=2)

#e2fsck -b 32768 /dev/ida/c1d0p1

e2fsck -b 32768 /dev/ida/c1d0p1
e2fsck 1.32 (09-Nov-2002)
Couldn't find ext2 superblock, trying backup blocks...
e2fsck: Bad magic number in super-block while trying to open /dev/ida/c1d0p1

-----------------------------
Others superblocks backups I tried to use but nothing happened
Is there any tools or software to recovery data on the RAID (actually Linux detects it as a disk).
Thanks for your help
