file table corrupt

[MikeL_4]

We had a case today where a bdf command came back with no display. Upon looking into it the mnttab file had a zero "0" size to it.
I first tried the mount command to mount file systems, but it came back with message: file system table may be corrupt.
I rebooted to get out of this, but is there anything else that could of been done, or any idea as to what could of caused this ??

Thanks

rebooting may have caused an fsck to be run on the filesystems, if marked as corrupt.

If so, you can run manually on a non-mounted system

fsck /dev/xxx

options such as -y, -o full could be recommended.

If any files were salvaged, they will be in each file systems lost+found directory. Take a look, if there are files there, they are missing from the fs. ( if you can tell what they are, you can put them back)

Normally it means that the /etc/mnttab file is corrupt. What you have to do is this:

# mv /etc/mnttab /etc/mnttab.org
# mount -v -a

Lots of thigns can cause it.

Here is how to fix it.

A script:

#!/usr/bin/sh

fsck -F vxfs -o full -y $1

$1 is the character device. /dev/vg00/rlvol2
