Hello,
I'm not a computer expert, so I will try to explain it as best as possible.
Here some details:
I'm using i386 current.
I've a LSI Megaraid 8x controller on which 3 physical drives are connected.
>From these 3 physical drives I have configured 3 logical drives:
$ sudo bioctl ami0

Here is my /etc/fstab:
/dev/sd0a / ffs rw 1 1
/dev/sd2a /altroot ffs xx 0 0
/dev/sd1a /tmp ffs rw,nodev,nosuid 1 2
/dev/sd0e /usr ffs rw,nodev,softdep 1 2
/dev/sd1d /usr/obj ffs rw,nodev,nosuid,softdep 1 2
/dev/sd0d /var ffs rw,softdep 1 2
/dev/sd2d /home ffs rw,nodev,nosuid,softdep 1 2
/dev/sd1e /home/sources ffs rw,nodev,nosuid,softdep 1 2
Sometimes when I boot sd2 is not mountable as the disklabels have disappeared
on the sd2 disk.
Here is a "disklabel sd2", when in single user mode and when the disklabels
have disappeared.
# /dev/rsd2c:

Here is the disklabel when everything is ok:
# Inside MBR partition 3: type A6 start 63 size 1289425032

d: 1285238784 4194304 4.2BSD 2048 16384 323 # Cyl 2048 -629605
I'm able to restore the labels with:
disklabel -R sd2 /var/backups/disklabel.sd2.current
But this is pretty scary ... as you see in fstab, one of those partitions is my
/home directory
When I shutdown the workstation, everything looks fine, it does not show me any
problems.
>From time to time at random intervals this problems appears.
I would really appreciate if someone could give me some ideas or help on how to
solve this problem.
Here is my dmesg:
