Ok, so mirrors resilver faster. But, it is not uncommon that another disk shows problem during resilver (for instance r/w errors), this scenario would mean your entire raid is gone, right? If you are using mirrors, and one disk crashes and you start resilver. Then the other disk shows r/w errors because of the increased load - then you are screwed? Because large disks take long time to resilver, possibly weeks?
In that case, it would be preferable to use mirrors with 3 disks in each vdev. Trimorrs. Each vdev should be one raidz3. -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
