UFS mount problem

Hi all,

ES40, 5.1 PK5

We had a system crash last night. We have a large(ish) number
of UFS filesystems (120) and after the fsck step the machine
proceeded through the reboot into multiuser mode as if all
was well. I then subsequently discovered that two of the filesystems
had not mounted. I have no copy of the console output during
the reboot (must get a laptop as my console terminal), so I
cant say whether these two filesystems were referenced anywhere,
but are there any known problems with this number of filesystems,
or with fsck'ing such a large number at once?
When I fsck'd them manually, they reported no problems and
mounted satisfactorily.

This has not happened before, but a possibly related symptom
is that one particular filesystem (not one of the two which
failed to mount) never seems to umount cleanly after a shutdown,
and always requires fsck'ing on reboot. I dont reboot very often
so have neglected to investigate this so far.

Any ideas anyone? I'm a bit bothered that something is dying
somewhere...

Cheers,
Terry.
