I'm using vinum in a RAID 5 setup. I have an SCA encloser that holds 6
disks. I have a pair of 4GB system disks (One has /, swap and /usr. /var is
in /usr under /usr/var. The other disk is laid out the same and I use tar
to back up the primary disk.) and 4 34GB disks that were mounted in /raid.
I was using vinum to do raid 5 across all 4 of the 34GB disks and all was
working great. I decided I wanted to upgrade to 4.3-20010502-STABLE, that's
when things went wrong. I presumed that swapping da0 and da1 (the 2 4GB
disks) would allow me to do a fresh install on the backup disk. This worked
and I proceeded to copy the important config files and recompile my kernel
and such. I attempted to mount the vinum disk and realized that I needed to
remake the devices in the /dev directory so I initiated the "vinum makedev"
command, no problem. I then did a list of the config and all looked good.
When I tried to start the I got error messages. I decided to back out and
reboot the system swapping disks thus reverting the system back to
4.1-RELEASE. I'm still having problems. I have a subdisk now that is
saying it's crashed. I was wondering if anyone you might have a recommend
fix for this with out data loss.
I have all the output from DMESG, /var/log/messages, vinum l, vinum_history
and such for the old and the new systems. I can forward it to any
individual who would be willing to take a look off the list. (it's rather
long)
Anything might help.
Thanks!
