Trying to figure out error in file system check


Hi,

I am seeing a [FAILED] message as my RHAS3 is booting, and I get dropped into a shell to repair the filesystem.

However, it's not clear to me where the error is. I've used fsck for all the partitions (/usr, /export/home, /boot, /tmp), I ran fsck -n on the root parition, and they all seem okay. I get a 'Bad magic number in super-block' message if I try to run fsck on the swap partition, but running fsck on a swap partition doesn't make sense (right?). Apart from all that the only other partition is a zero-length extended partition.

Anyways, I'd be grateful for any pointers with this problem.

Regards,
Colm.

Hi coolmmagoo,
You are right. The swap and extended partitions are not fsck'able. The only way I know to identify the partition in error is to stay attempt to the procedure. During the "boot fsck" it displays the partition it is checking. Until today I couldn't see any register in the system log about a file system with problems at boot, even because the system is not fully up.
The right way to check for confidence is to use another media to boot, for example, your rescue cd, then fsck each linux or reiserfs partition using -f to force the check even if the system thinks it is ok. It is not applicable to any windows partition also.
In spite of the modern partitions as ext3 are journaled, the docs recommend us to check the partitions periodically. So, I suggest you to boot your cd, enter 'rescue' mode, enter 'fdisk -l' at the prompt to identify the linux partitions, and enter "e2fsck -f -y <partition>" for each one.
