I have a filesystem on a box running SuSE 8.0 (2.4.18) which shares a couple
of large filesystems via NFS. It's been behaving itself quite nicely for the
last 273 days. Suddenly, weird things are happening on one of these
filesystems - it suddenly becomes unwritable because it's mounted read-only.
Attempting to do mount -o remount,rw FILESYSTEM fails with a message
that the filesystem is write protected and hence is being mounted read-only.
The easy enough fix is to stop the NFS server, umount the filesystem , mount
the filesystem and start the NFS server again, which doesn't bother the
clients a whole lot (although VMWare 'doze instances on clients get
temporarily VERY sad) but I'm wondering what the hell causes this. ls -lu on
/bin/mount shows that it hasn't been used for hours, so it's not a wayward
script or something.
