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...)
