=== Checks ===
Mounted?
zfs get mounted mainframe/iocage
Snapshots?
zfs list -t snapshot mainframe/iocage
Destroy:
zfs destroy -r mainframe/iocage
Expand zpool
Scan current SCSI devices for changes
for i in /sys/class/scsi_device/*/device/rescan; do echo "- - -" > $i; done
8MB partition at the end of the disk may be deleted (perhaps an artefact from the Solaris days?)
parted /dev/sdb rm 9
Increase ZFS partition to maximum size
growpart /dev/sdb 1
Expand the pool
zpool online -e ZPOOLNAME /dev/sdb
