Create a RAID 1 style file system across two devices:
zpool create tank mirror /dev/sdb /dev/sdc
Create a RAIDZ2 file system with all the features:
zpool create -f tank -o ashift=12 raidz2 /dev/sda /dev/sdb /dev/sdc /dev/sdd zfs set compression=lz4 tank zfs set xattr=sa tank zfs set acltype=posixacl tank zpool set autoexpand=on tank
Add another pair of mirrored drives to create an array similar to RAID 10:
zpool add tank mirror /dev/sdd /dev/sde
Display information about the file system:
zpool status zpool list zpool list -v zfs list zfs list -t all zfs get all
Disable a drive:
zpool offline tank /dev/sdj
Replace an active drive:
zpool replace -f tank /dev/sds /dev/sdt
Scrub an array:
zpool scrub tank
Enable autoexpand for a zpool (allows growing arrays by replacing drives with larger models):
zpool set autoexpand=on tank
Enable file system compression:
zfs set compression=lz4 tank
Create a new file system:
zfs create tank/partition1
Remove a drive, even if resilvering
zpool detach tank sdc
Clear ZFS info from a drive
zpool labelclear /dev/sdt
Remove a drive from a mirror of sdc+sdd, then attach a new drive sde
zpool detach tank sdc zpool attach -f tank sdd sde
