fsck failes after crash

[MoshiachNow]

Hi,

URGENT !!!!

What can be done with a filesystem that after a crash shows repeatadly in fsck:
fsck -y /dataVolumes/SMP.7.0


** Checking /dev/rslv7.0 (/dataV)
** Phase 0 - Check Log
log redo processing for /dev/rslv7.0
** Phase 1 - Check Blocks and Sizes
Block 719329392: invalid Inode=0 fragment=55c030e
Block 0: duplicate Inode=0 fragment=0
Block 131072: duplicate Inode=0 fragment=4000
Block 0: duplicate Inode=0 fragment=0
Block 0: duplicate Inode=0 fragment=0
Block 0: duplicate Inode=0 fragment=0
Block 256: duplicate Inode=0 fragment=20
Block 0: duplicate Inode=0 fragment=0
Block 8: duplicate Inode=0 fragment=1
Block 0: duplicate Inode=0 fragment=0
Block 0: duplicate Inode=0 fragment=0
Excessive duplicate blocks Inode=0 (CONTINUED) "Long live king Moshiach !"

I think the Filesystem is defragmented.

defragfs Command will help jo to defrag your FS.
How much you have run fsck ?
Did you have run fsck with "-p"
I think to recreate the Superblock will not halp to fix the Problem.

HI,

The FS is corrupted AFTER crash,not defragmented.

I'm running fsck -y,which is even better. "Long live king Moshiach !"

Just a point; `fsck -y` is not necessarily better, it will fix every problem and when you answer yes to inodes it may delete them. `fsck -p` is a safer approach.

As for the filesystem having the fsck errors, it is because the box is crashing and causing the errors. You need to find the source of the crash and correct it and the fsck errors will go away.

How would you start to trace the source of a crash like this?

Hello levw,

1) If you have a valid dump - let IBM look at dump to see why system crashed.
2) boot the system from CD rom(aix 433) then go into the system and start shell without mounting file system and run fsck.
3) What level of AIX runing.

Thanks,guys

ALl I was looking for is the way to recover the specific FS after this specific crash - fsdb or something alike.
I know excatly why and how it happened - was just looking for an exotic way to recover. "Long live king Moshiach !"
