Oh, and you don't have to re-create the pool in order to use the extra space. Just "zpool replace" the drives with larger ones, then "zpool export" the pool, and "zpool import" the pool, and the extra space becomes available. I did this on my home server a couple of months ago. I started with 3x 120 GB drives split into 3 slices (2 GB for use by gmirror for /, 1 GB for use as swap, rest for use by ZFS). Later I moved / onto a 2 GB USB key. A simple iteration of "zpool replace pool ad4s1 ad4" for each of the three drives, an export and import, and I had an extra 9 GB of space in my pool. -- Freddie Cash [email protected]
