Let''s say you are paranoid and have built a pool with 40+ disks in a Thumper. Is there a way to set metadata copies=3 manually? After having built RAIDZ2 sets with 7-9 disks and then pooled these together, it just seems like a little bit of extra insurance to increase metadata copies. I don''t see a need for extra data copies which is currently the only trigger I see for that. This message posted from opensolaris.org

Take a look at dmu_get_replication_level(). - George
