If that non-redundant vdev dies, you lose the entire pool. Are you willing to take that risk, if one of the new drives is already DoA? -- Freddie Cash fjwc...@gmail.com ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

Without the -f zpool will stop and warn you that you have a "mismatch" in reliability.

[zfs-discuss] Question: adding a single drive to a mirrored zpool
Hello, I have a zpool consisting of several mirrored vdevs. I was in the middle of adding another mirrored vdev today, but found out one of the new drives is bad. I will be receiving the replacement drive in a few days. In the mean time, I need the additional storage on my zpool. Is the command to add a single drive to a mirrored zpool: zpool add -f tank drive1? Does the -f command cause any issues? I realize that there will be no redundancy on that drive for a few days, and I can live with that as long as the rest of my zpool remains intact.
