FreeNAS does not restart when using 3ware controllers and ZFS
|Reported by:||bvowk||Owned by:|
I have several systems with 3ware SAS cards that do not reboot when they have a 3ware card and a ZFS pool. It hangs after the "Uptime: " message, and requires a hard reboot to get it to continue. If there is no ZFS pool when reboot is called, the restart happens normally. The hang only happens when we reboot a machine with a 3ware card, and an active ZFS pool. This has been verified by switching out the raid card and keeping all other variables static. This is also a problem in the most recent BETA.
This appears to be a problem in FreeBSD, which is discussed here:
Unloading the ZFS module seems to solve the issue as described.
