Hi!
I've been testing ZFS, and would like to use it on SAN attached disks in
our production environment, where multiple machines can see the same
zpools. I'm having some concerns about importing/exporting pools on
possible failure situations. If box that was using some zpool crashes

Thanks for the fast reply. :) We'll have look into the Cluster solution.

realize that the pool is now in use by the other host. That leads to two
systems using the same zpool which is not nice.
Is there any solution to this problem, or do I have to get Sun Cluster 3.2 if
I want to serve same zpools from many hosts? We may try Sun
You could use SAN zoning of the affected LUN's to keep multiple hosts
from seeing the zpool. When failover time comes, you change the zoning
to make the LUN's visible to the new host, then import. When the old
host reboots, it won't find any zpool. Better safe than sorry
Or change the
