[ale] mtab inconsistancies

[Lightner, Jeff]

I've seen devices that have problems get mounted read only when they
should be read/write.   However, I've not bothered to look at mtab to
see if it was reporting differently than mount.  Usually the issue has
been that there was a disk or filesystem issue that caused the
filesystem to mount read only to prevent further damage. 

I've not seen it with an NFS mount though.  I'm wondering if perhaps the
issue is that your fstab is trying to mount it read write and it is
being exported read only or vice versa?

Speaking of mtab...

Has anyone seen this and know what could cause it and better how to
prevent it? (make careful not of the RO vs RW atributes)

mount reports
/dev/hda2 on /var type xfs (ro)

cat /etc/mtab and cat /proc/mounts report
/dev/hda2 /var xfs rw 0 0

(results above are simulated)

The mount is no longer writable until a mount -o remount,rw.
Also the mount was recently remounted thru NFS on a different mount
point. Two other mounts are unaffected.

I'm baffled.
