Problems with fsck

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.

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
 
Disk /dev/sda: 255 heads, 63 sectors, 29187 cylinders

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.
