Description

System Description

Two systems as described in https://www.illumos.org/issues/4454 are using vice versa FC exported LUNs based on
ZFS ZVols. Every system has a zpool with 2 mirrored FC devices for providing NFS shares with synchronous storage backend,
both zpools are imported for active-active configuration.

Kernel panic

If the remote system dies on a kernel panic as described in issue 4454 above, the local system only coupled
by FC Luns also happened to panic.

Please see the attached crash dump file and screenshot, a full dump is also available if helpful.

Thx a lot.

Are you locally importing the volume, or only over the sd driver?

Can you provide the contents of "zpool list -v"

Thanks.

As described in #4454:

On the disk pool consisting of disks connected by dual-path SAS there are ZVOLs, exported as COMSTAR LUNs via fibre channel (emlxs in target mode).
These LUN's are imported via fcp as devices (emlxs in initiator mode), and a zpool mirror is build from one from the local exportet target, one from the remote system.
So there are two layers of ZFS in the system. All disk devices (SAS or FC) should be presented by sd.
