Hi
I've been testing various vinum combinations to see which is best for a
mail server. The machine I'm using has 7 4gb SCSI disks with da0s1 as
the root partition and the other 6 as a striped vinum volume. I'm
getting a reproducable kernel panic when using "newfs -v
/dev/vinum/raid10". I wouldn't be surprised if it's a hardware problem -
the equipment is quite old. However, I'm not sure how to find out.
I've built a debug kernel as described in the FAQ and attached the
backtrace.
Specs follow. If anything else is needed, please ask. This machine isn't
going anywhere for a while :-)
Hardware:
Dual PII/350 cpu
256mb RAM
7 x 4gb IBM SCSI disks (4 x DDRS-34560W S97B, 3 x IBM DCAS-34330W S65A)
Adaptec aic7890/91 Ultra2 SCSI adapter

Nothing related to the crash in /var/log/messages or
