ZPOOL-LIST(8) System Manager's Manual ZPOOL-LIST(8)

NAME

zpool-list — list information about ZFS storage pools

SYNOPSIS

zpool list [-HgLpPv] [-o property[,property]…] [-T u|d] [pool]… [interval [count]]

DESCRIPTION

Lists the given pools along with a health status and space usage. If no pools are specified, all pools in the system are listed. When given an interval, the information is printed every interval seconds until killed. If count is specified, the command exits after count reports are printed.

Display vdev GUIDs instead of the normal device names. These GUIDs can be used in place of device names for the zpool detach/offline/remove/replace commands.
Scripted mode. Do not display headers, and separate fields by a single tab instead of arbitrary space.
property
Comma-separated list of properties to display. See the zpoolprops(7) manual page for a list of valid properties. The default list is , , , , , , , , , .
Display real paths for vdevs resolving all symbolic links. This can be used to look up the current block device name regardless of the /dev/disk path used to open it.
Display numbers in parsable (exact) values.
Display full paths for vdevs instead of only the last component of the path. This can be used in conjunction with the -L flag.
u|d
Display a time stamp. Specify u for a printed representation of the internal representation of time. See time(2). Specify d for standard date format. See date(1).
Verbose statistics. Reports usage statistics for individual vdevs within the pool, in addition to the pool-wide statistics.

EXAMPLES

Example 1: Listing Available ZFS Storage Pools

The following command lists all available pools on the system. In this case, the pool zion is faulted due to a missing device. The results from this command are similar to the following:

# zpool list
NAME    SIZE  ALLOC   FREE  EXPANDSZ   FRAG    CAP  DEDUP  HEALTH  ALTROOT
rpool  19.9G  8.43G  11.4G         -    33%    42%  1.00x  ONLINE  -
tank   61.5G  20.0G  41.5G         -    48%    32%  1.00x  ONLINE  -
zion       -      -      -         -      -      -      -  FAULTED -

Example 2: Displaying expanded space on a device

The following command displays the detailed information for the pool data. This pool is comprised of a single raidz vdev where one of its devices increased its capacity by 10 GiB. In this example, the pool will not be able to utilize this extra capacity until all the devices under the raidz vdev have been expanded.

# zpool list -v data
NAME         SIZE  ALLOC   FREE  EXPANDSZ   FRAG    CAP  DEDUP  HEALTH  ALTROOT
data        23.9G  14.6G  9.30G         -    48%    61%  1.00x  ONLINE  -
  raidz1    23.9G  14.6G  9.30G         -    48%
    sda         -      -      -         -      -
    sdb         -      -      -       10G      -
    sdc         -      -      -         -      -
