[zfs-discuss] How to set ZFS metadata copies=3?
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.

Take a look at dmu_get_replication_level(). - George ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
