Greetings all -
I've got a completely reproducible panic when issuing a
'gmirror status' command on a recently deactivated gmirror.
NOTE: This only happens on a machine with more than 1 CPU.
I filed a bug report on it:
http://www.freebsd.org/cgi/query-pr.cgi?pr=184985
Script to reproduce the panic:
(assumes /dev/ada0p3 is a scratch partition)
while :
do
gmirror label -v scratch /dev/ada0p3
newfs /dev/mirror/scratch
mount /dev/mirror/scratch /mnt
umount -f /mnt
gmirror deactivate scratch /dev/ada0p3
gmirror status scratch
done
I've attached the core.txt.0 file from the crash under 10.0-RC2.
Probably stripped by the mailing list. A copy is at
