zpool

Manage ZFS pools.

• Show the configuration and status of all ZFS zpools:

zpool status

• Check a ZFS pool for errors (verifies the checksum of EVERY block). Very CPU and disk intensive:

zpool scrub {{pool_name}}

• List zpools available for import:

zpool import

• Import a zpool:

zpool import {{pool_name}}

• Export a zpool (unmount all filesystems):

zpool export {{pool_name}}

• Show the history of all pool operations:

zpool history {{pool_name}}

• Create a mirrored pool:

zpool create {{pool_name}} mirror {{disk1}} {{disk2}} mirror {{disk3}} {{disk4}}

• Add a cache (L2ARC) device to a zpool:

zpool add {{pool_name}} cache {{cache_disk}}
