Hello Greg,
Well, unfortunately I wasn't able to find the dot files you mention in the
documentation under /usr/src/sys/modules/vinum/.gdb*
I've tried this particular configuration under FreeBSD 5.2.1-REL and
5.2-CURRENT and have the same problems under both. I'm using this exact config
on FreeBSD 4.9 without problems. I have not made changes to the system source.
My vinum list output is as follows:
2 drives:
D d1 State: up /dev/ad1s1d A: 258/37122 MB (0%)
D d0 State: up /dev/ad0s1d A: 258/37122 MB (0%)
4 volumes:
V rootvol State: up Plexes: 2 Size: 2048 MB
V usrvol State: up Plexes: 2 Size: 12 GB
V varvol State: up Plexes: 2 Size: 10 GB
V datavol State: up Plexes: 2 Size: 12 GB
8 plexes:
P rootvol.p1 C State: up Subdisks: 1 Size: 2048 MB
P usrvol.p1 C State: up Subdisks: 1 Size: 12 GB
P varvol.p1 C State: up Subdisks: 1 Size: 10 GB
P datavol.p1 C State: up Subdisks: 1 Size: 12 GB
P rootvol.p0 C State: up Subdisks: 1 Size: 2048 MB
P usrvol.p0 C State: up Subdisks: 1 Size: 12 GB
P varvol.p0 C State: up Subdisks: 1 Size: 10 GB
P datavol.p0 C State: up Subdisks: 1 Size: 12 GB
I've tried to also detach individual plexes to see if it would eliminate the
problem, without luck.
Unfortunately my vinum history and /var/log/messages has no error messages or
anything out of the ordinary for vinum or any other errors for that matter.
Since I have not yet setup the remote debug the details of the crash are as
follows.
Right before the crash I see a message stating, configuration already read
from d1.
Crash is Fatal trap 12: page fault while in kernel mode
fault virtual address 0x60
fault code: supervisor read, page not present
inst ptr: 0x08:0xc050ebd6
stack ptr: 0x10:0xe06c29c4
frame ptr: 0x10:0xe06c29c4
code segment: base 0x0 limit 0xfffff type 0x1b
DPL 0, pres 1, def32 1, gran 1
processor eflags: interupt enabled, resume, IOPL=0
current process: 91 (vinum)
kernel type 12 trap, code 0
Stopped at devsw+0x6: cmpl $0,0x60(%eax)
running where in the debugger gives me the last few func calls:
devsw
initdrive
read_drive_label
check_drive
vinum_scandisk
vinum_super_ioctl
vinum_ioctl
...
-thanks!
George
