I was asked a few interesting questions by a fellow co-worker regarding ZFS and after much google-bombing, still can't find answers. I've seen several people try to ask these questions, but only to have been answered indirectly.
If I have a pool that consists of a raidz-1 w/ three 500gb disks and I go to the store and buy a fourth 500gb disk and add it to the pool as the second vdev, what happens when that fourth disk has a hardware failure? The second question is lets say I have two disks and I create a non-parity pool [2 vdevs creating /tank] with a single child filesystem [/tank/fscopies2/] in the pool with the copies=2 attribute. If I lose one of these disks, will I still have access to my files? If you were to add a third disk to this filesystem as a third vdev at a future point in time, would there be any scenario where a hardware failure would cause the rest of the pool to be unreadable? -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
