When I started using zfs a while back, I got the impression that setting my home server up with mirror sets rather than some kind of zraid would offer the most reliable setup for my data.
My data is just what you'd expect on a home lan... no real commercial value involved. I've since created 2 zpools beyond rpool each with a single mirror set. I happened to notice someones' config posted here recently where a single zpool was made up of several mirror sets.

My needs are small, and the zfs server acts mostly as NAS for home lan. I've been thinking the mirrors on the zfs server were the final stopping place for my backups. I'm thinking the mirrors are reliable enough that I don't do even more backups of the backup zpools. I mean other than auto snapshots. I'm thinking a crippled mirror can be recovered rather than needing a backup of it. And that short of 2 mirrored disks dieing at the same time. I'm in pretty good shape. Am I way wrong on this, and further I'm curious if it would make more versatile use of the space if I were to put the mirrored pairs into one big pool containing 3 mirrored pairs (6 discs) So where they had been separate pools, where one might fill up while another stayed fairly empty, if they were all in a single pool none would fill up until they all filled up. _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
