[zfs-discuss] possible to remove a mirror pair from a zpool?
Suppose the requirements for storage shrink ( it can happen ) is it possible to remove a mirror set from a zpool? Given this : # zpool status array03 pool: array03 state: ONLINE status: The pool is formatted using an older on-disk format. The pool can still be used, but some features are unavailable. action: Upgrade the pool using 'zpool upgrade'. Once this is done, the pool will no longer be accessible on older software versions. scrub: resilver completed after 0h41m with 0 errors on Sat Jan 9 22:54:11 2010 config: NAME STATE READ WRITE CKSUM array03 ONLINE 0 0 0 mirror ONLINE 0 0 0 c2t16d0 ONLINE 0 0 0 c5t0d0 ONLINE 0 0 0 mirror ONLINE 0 0 0 c5t1d0 ONLINE 0 0 0 c2t17d0 ONLINE 0 0 0 mirror ONLINE 0 0 0 c5t2d0 ONLINE 0 0 0 c2t18d0 ONLINE 0 0 0 mirror ONLINE 0 0 0 c2t20d0 ONLINE 0 0 0 c5t4d0 ONLINE 0 0 0 mirror ONLINE 0 0 0 c2t21d0 ONLINE 0 0 0 c5t6d0 ONLINE 0 0 0 mirror ONLINE 0 0 0 c2t19d0 ONLINE 0 0 0 c5t5d0 ONLINE 0 0 0 spares c2t22d0AVAIL errors: No known data errors Suppose I want to power down the disks c2t19d0 and c5t5d0 because they are not needed.
