Can't mount showing 0506-342 The superblock on /dev/fslv00 is dirty

Dear All

Last day in Aix 5.2 server by executing
# df –g

I found following:

Filesystem GB blocks Free %Used Iused %Iused Mounted on
.
.
/dev/fslv00 58.00 136.70 -135% 212103 1% /sprod

After shutting down by following command

# shutdown –h

And when the Aix start there is no /sprod

# df –g

result not showing /sprod

!!! I tried to mount it by

# mount /sprod

and found

Replaying log for /dev/fslv00.
Failure replaying log: -1
mount: 0506-324 Cannot mount /dev/fslv00 on /sprod: The media is not formatted or the format is not correct.
0506-342 The superblock on /dev/fslv00 is dirty. Run a full fsck to fix.

Then tried

# fsck

Results like following …

The current volume is: /dev/hd1
File system is currently mounted.
fsck: Performing read-only processing does not produce dependable results.
**Phase 1 - Check Blocks, Files/Directories, and Directory Entries
**Phase 2 - Count links
**Phase 3 - Duplicate Block Rescan and Directory Connectedness
**Phase 4 - Report Problems
**Phase 7 - Verify File/Directory Allocation Maps
File system inode map is corrupt (NOT FIXED)
**Phase 8 - Verify Disk Allocation Maps
2555904 kilobytes total disk space.
1774 kilobytes in 533 directories.
2484237 kilobytes in 21467 user files.
68288 kilobytes are available for use.
fsck: Performing read-only processing does not produce dependable results.

And also tried with #fsck –p /sprod and fsck -p /dev/fslv00 and also # fsck -y /sprod and fsck -y /dev/fslv00
but still faild.

Then I tried to replace the first super block by second super block using

dd count=1 bs=4k skip=1 seek=31 if=/dev/fslv00 of=/dev/fslv00


But still failed to mount the /sprod and getting same error as before

Failure replaying log: -1
mount: 0506-324 Cannot mount /dev/fslv00 on /sprod: The media is not formatted or the format is not correct.
0506-342 The superblock on /dev/fslv00 is dirty. Run a full fsck to fix.


Please help me. Is there any way I can mount the /sprod directory or at least is there any data recovery software or what ever by using which I can recover those data from that directory?

What is the OS level ("instfix -i | grep "AIX_ML") and the filesystem you are using (JFS or JFS2)? If JFS2 are you using an inline log or an external log volume?

You have obviuously followed the tip of Martin Trcka here and i wonder if it was 100% applicable to you: JFS and JFS2 are somewhat different.
