ZFS Cheatsheet

This is a zfs cheatsheet that I’ll be able to keep it for future reference. The cheatsheet will be divided into two parts, zpool comands and zfs commands.

Zpool related

To create a mirror ( min two devices )
zpool create mpool mirror   

To create a stripe ( min 1 device )
zpool create spool   

To create raidz (min 3 devices )
zpool create raidzpool raidz    

Obtain all properties from a zpool
zpool get all pool_name

ZFS related

To create normal zfs filesystem
zfs create -o mountpoint=/path/to/mount testpool/example1

To create a snapshot
zfs create snapshot testpool/example1@snap_name

To create a recursive snapshot
zfs create -r snapshot testpool/example1@snap_name

To delete a snapshot
zfs delete testpool/example1@snap_name

To delete recursively snapshot
zfs delete -r testpool@snap_name 

To send a snapshot to another host.
zfs send testpool/dataset@snap_name |ssh remote_host zfs recv testpool2/new_dataset@snapshot

To send a dataset and all of it's descendants datasets with options
zfs send -vR testpool@backup |zfs receive -vd -F test2pool

Defining several option while creating a zfs dataset.
zfs create -o quota=10G -o recordsize=8k -o mountpoint=/mnt/test,compression=on,dedup=on rpool/test_ds

Obtain all the properties for a zfs dataset
zfs get all pool_name/dataset

 
NOTE: While creating a new dataset with options, the ones that require numbers like quota and recordsize need to have separate -o.
