Corruption In Filesystem

[rajeshbahl]

We met with this problem a few days back:-

Our server having three hard disks,one eight port specialix serial controller card and 96MB RAM runs on SCO openserver 5.Suddenly the following message appeared:-
Error log overflow
Serial:Garbage or loose cables on dev8, port shutdown.

After this the server hanged.As there was no other way, we had to reboot the machine.After rebooting we found the two volumes located on third hard disk did not mount,instead the following message came while mounting them:
NO TRANSACTIONS PENDING
could not mount /dev/forkdata, possible damaged filesystem

and a similar message for the second filesystem.

We tried to run fsck and then fsck -ofull on these filesystems.Absolutely no error appeared. We ran fsck -d -ofull and got the following mesage:-

sync log ino 5
sync log size 32768
saving stale offset 0
skipping offset 0
Slog header:cksum 0000e4e8 tstamp 00046772 p stamp 00000000 size 3184
Slog entry:ino 10 off 678864 len 3120 origlen3120 reclen 3184 time 3c899e68
writing sync log entry ino 10 off 678864 len 3120

We tried to mount the filesystem again. The foolowing message came:-

possibly damaged filesystem,mount failed:No space left on device (error 28)

We again tried another method.Scoadmin----filesystems----filesystem manager---check and repair the required filesystem

This checked the filesystem and at the end said: filesystem is dirty

Nothing seems to work.
Any one having idea about this trouble,please help !


Thanks In Advance

Sounds like a hardware problem- bad controller most likely. The message from the serial card was probably unrelated, but I'd pull it temporarily just to be sure it isn't cauing problems with other hardware.

If everything checks out, you probably have to remake those fs's and restore from backup. Tony Lawrence
