I would like to reduce the size of a zpool, but am unsure if it is possible, or if it is how to go about doing so safely. The set-up: 1) 75GB SATA internal drive 1 /dev/dsk/c1d0s0 is in use for live upgrade /. /dev/dsk/c1d0s1 is currently used by swap. /dev/dsk/c1d0s3 is currently mounted on /. /dev/dsk/c1d0s7 is part of active ZFS pool A
2) 75GB SATA internal drive 2 /dev/dsk/c2d0s7 is part of active ZFS pool A 3) external 250GB firewire drive 7 /dev/dsk/c7t0d0s0 is part of active ZFS pool B I need to enlarge the boot slices on drive 1, but to do so I must reduce c1d0s7 size which is part of zpool A (I'd like to do the entire drive 1 ZFS boot, but can wait on trying that). My plan was to: 1) send snapshots of the zpool A file systems to drive 7, then 2) destroy zpool A 3) reformat drive 1 and reinstall the OS, either on zfs or ufs 4) create a new zpool AA using only drive 2 5) import the saved zpool A file systems into zpool AA My main question is, can I import zpool A filesystems into zpool AA even though zpool AA will be smaller than zpool A was when the filesystems were sent? The actual zpool A filesystems are currently using only a small fraction of the entire zpool A and would use only a fraction of the new zpool AA size as well.
