You accidentally added 4 & 5 without mirroring. Not true. 4 & 5 may have been added initially as a mirror, then 5 detached from the mirror and later added as a single drive (rather than reattached to 4 as a mirror again). It can be easy to confuse "add" and "attach" commands. > The only > way to fix it is to (a) add redundancy to both 4 & 5 Yes, attach 2 new disks, one to each of 4 and 5, to turn those vdevs (back) into mirrors. >, or (b) destroy and > recreate the pool, and this time be very careful that you mirror 4&5. Unfortunately, yes, if you can't attach more disks, this is necessary, since it's not currently possible to remove a top-level vdev. -- Dan. pgpBxFtuuWR4L.pgp Description: PGP signature ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

An easy way to tell is taking a look at the zpool history command for this pool.

You accidentally added 4 & 5 without mirroring. The only way to fix it is to (a) add redundancy to both 4 & 5, or (b) destroy and recreate the pool, and this time be very careful that you mirror 4 & 5. ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
