ZPool Usage

zpool create <POOL_NAME> <RAID_LEVEL> <DEVICE>
zpool create mypool raidz da{0,1,2}
zpool destroy <poolname>
zpool destroy mypool
zpool add
zpool status -v <POOL_NAME>
zpool list

Remove a failed disk

zpool offline <POOL_NAME> /dev/gptid/00000000-0000-0000-0000-000000000000

Replace Offline disk with new

zpool replace <POOL_NAME> /dev/gptid/00000000-0000-0000-0000-000000000000 /dev/da#

Note:/dev/da# should be the new disk


io statistics

zpool iostat mypool 30

This will display the IO statistics of the pool every seconds.


ZFS Usage

Create ZVOL

zfs create -V <VOLUME_SIZE> <VOLUME_PATH>
zfs create -V 200g mypool/myvol

Grow a ZVOL

zfs set volsize=200G mypool/myvol

Note: If using FreeNAS and the ZVOL is an iSCSI extent then you need to open and re-save the extent. This reloads the configuration for the iSCSI service and makes the changes visible to the initiators (VMWare, Windows, etc...)
