Hello Guys,
I am with a huge problem with a server here.
I have a contingency file server with RAID 5 ...
I replace a disk that failed yesterday .... The RAID was rebuild ... Then I umount the disk and run this command
#fsck.ext3 -vfy /dev/sda1
At the final output I have this :
Inode 29294598 has illegal block(s). Clear? yes
Illegal block #12 (879226656) in inode 29294598. CLEARED.
Illegal block #13 (3315620004) in inode 29294598. CLEARED.
Illegal block #14 (2340312175) in inode 29294598. CLEARED.
Illegal block #15 (3564345759) in inode 29294598. CLEARED.
Illegal block #16 (510048934) in inode 29294598. CLEARED.
Illegal block #17 (2568278150) in inode 29294598. CLEARED.
Illegal block #18 (538064865) in inode 29294598. CLEARED.
Illegal block #19 (2530322371) in inode 29294598. CLEARED.
Illegal block #20 (3624553377) in inode 29294598. CLEARED.
Illegal block #21 (4055744104) in inode 29294598. CLEARED.
Illegal block #22 (2167778488) in inode 29294598. CLEARED.
Too many illegal blocks in inode 29294598.
Clear inode? yes
Restarting e2fsck from the beginning...
Group descriptors look bad... trying backup blocks...
fsck.ext3: Invalid argument while checking ext3 journal for /dev/sda1
Well, I try to run the same command again and I see this :
#fsck.ext3 -vfy /dev/sda1
e2fsck 1.27 (8-Mar-2002)
Group descriptors look bad... trying backup blocks...
e2fsck: A block group is missing an inode table while checking ext3 journal for /dev/sda1
This message make me nervous, so I run tune2fs:
# tune2fs -l /dev/sda1

Then, I try to mount the filesystem :
# mount -t ext3 /dev/sda1 /backup
mount: wrong fs type, bad option, bad superblock on /dev/sda1,
or too many mounted file systems
The fdisk returns me :
# fdisk -l

Where is my mistake ??? How can I clean this filesystem and, the most important, how can I mount this filesystem.
Please, someone could help me with this ???
Regards.
