JFS intent log recovery-

[galenr]

Ladies and Gents-
An ugly scene... yikes !!! Question is: After a system crash, how does one replay transactions in a jfs intent log in order to restore file system metadata to a consistent state ?

THANX in ADVANCE

Galen,

It's done by fsck during reboot.

Do a full fsck if the system prompts you for that .. for example ..
# fsck -F vxfs -o full /dev/vg01/rlvol2
That would bring it back to a consistent state.

Here's my script.

# fsck -F vxfs -o full -y /dev/vg01/rsag
# fsck -F vxfs -o full -y /dev/vg01/rorcl_pgm
# mount /sag
# mount /orcl_pgm


I kind of forget what the -y is for. Its not in the manual, but this script is production which means it worked.

Much Obliged... Thank you all for your promt response.

Hi SEP,

-y option is 'go ahead' option.

when the prompt 'OK to clear log?' appears, automatically the option y is chosen and it proceeds to clear log.

I had replied to the other question with no question there.

Arrg, missed out on some points.

This is normally automatically done at boot time by fsck with no intervention needed.
