Listing Basic ZFS Information
You can list basic dataset information by using the zfs list command with no options. This command displays the names of all datasets on the system including their used, available, referenced, and mountpoint properties. For more information about these properties, see Introducing ZFS Properties.
For example:
# zfs list NAME USED AVAIL REFER MOUNTPOINT pool 476K 16.5G 21K /pool pool/clone 18K 16.5G 18K /pool/clone pool/home 296K 16.5G 19K /pool/home pool/home/marks 277K 16.5G 277K /pool/home/marks pool/home/marks@snap 0 - 277K - pool/test 18K 16.5G 18K /test |
You can also use this command to display specific datasets by providing the dataset name on the command line. Additionally, use the -r option to recursively display all descendents of that dataset. For example:
# zfs list -r pool/home/marks NAME USED AVAIL REFER MOUNTPOINT pool/home/marks 277K 16.5G 277K /pool/home/marks pool/home/marks@snap 0 - 277K - |
You can use the zfs list command with the mount point of a file system. For example:
# zfs list /pool/home/marks NAME USED AVAIL REFER MOUNTPOINT pool/home/marks 277K 16.5G 277K /pool/home/marks |
The following example shows how to display tank/home/chua and all of its descendent datasets.
# zfs list -r tank/home/chua NAME USED AVAIL REFER MOUNTPOINT tank/home/chua 26.0K 4.81G 10.0K /tank/home/chua tank/home/chua/projects 16K 4.81G 9.0K /tank/home/chua/projects tank/home/chua/projects/fs1 8K 4.81G 8K /tank/home/chua/projects/fs1 tank/home/chua/projects/fs2 8K 4.81G 8K /tank/home/chua/projects/fs2 |
