fsck -l LOG_FILE /dev/hdxy where xy designate the partition you want to check.

thanks for your reply.

1. so you have to run file system check for each seperate partition??? you can't do it once for all ???

2. any issues with the files when we do the file system check ???? Any serious issue that might happen???

3. you have the LOG_FILE on fsck but you didn't mention about the location. how does it work????

thanks again

Check out the man pages for fsck, but I believe the -A flag will cause fsck to examine each partition in your fstab. As for question 2, if you've got damaged files, then fsck will attempt to repair them. That repair action will either succeed or fail; if it succeeds, great, if it fails, you may be SOL. I'm not sure exactly what kinds of options you might have to repair a corrupted file if fsck cannot solve them. I'd recommend searching other threads here at LQ or Googling for more info. Good luck with it. -- J.W.

Here is a link containing a script for /etc/init.d/ that runs fsck at boot.
You may want to run this script for just run level 1.

I didn't see it mentioned but you want to mount a partition readonly (ro) before running fsck.

One of the numbers at the end of the /etc/fstab entry concerns fsck checking.

You may want to use tune2fs to reduce the maximum mount count for the partitions. This will run fsck during bootup automatically more often.
