[OmniOS-discuss] ZFS on iSCSI Target. OmniOS as Initiator

[Mark Harrison]

If you have the pool on the raw device (i.e. you haven't created any
slices/partitions and instructed zfs to use the whole 'disk'), and the
device suddenly appears to the OS with a larger size, then ZFS will
use all the space available. This also applies to physical drives,
where if you replace all the mirrored drives in a pool or top level
vdev with larger drives, the pool will suddenly be larger.
