.Sh NAME
.Nm zpool-list
.Nd list information about ZFS storage pools
.Sh SYNOPSIS
.Nm zpool
.Cm list
.Op Fl HgLpPv
.Op Fl j Op Ar --json-int, --json-pool-key-guid
.Op Fl o Ar property Ns Oo , Ns Ar property Oc Ns …
.Op Fl T Sy u Ns | Ns Sy d
.Oo Ar pool Oc Ns …
.Op Ar interval Op Ar count
.
.Sh DESCRIPTION
Lists the given pools along with a health status and space usage.
If no
.Ar pool Ns s
are specified, all pools in the system are listed.
When given an
.Ar interval ,
the information is printed every
.Ar interval
seconds until killed.
If
.Ar count
is specified, the command exits after
.Ar count
reports are printed.
.Bl -tag -width Ds
.It Fl j , -json Op Ar --json-int, --json-pool-key-guid
Display the list of pools in JSON format.
Specify
.Sy --json-int
to display the numbers in integer format instead of strings.
Specify
.Sy --json-pool-key-guid
to set pool GUID as key for pool objects instead of pool names.
.It Fl g
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.
.It Fl H
Scripted mode.
Do not display headers, and separate fields by a single tab instead of arbitrary
space.
.It Fl o Ar property
Comma-separated list of properties to display.
See the
.Xr zpoolprops 7
manual page for a list of valid properties.
The default list is
.Sy name , size , allocated , free , checkpoint, expandsize , fragmentation ,
.Sy capacity , dedupratio , health , altroot .
.It Fl L
Display real paths for vdevs resolving all symbolic links.
This can be used to look up the current block device name regardless of the
.Pa /dev/disk
path used to open it.
.It Fl p
Display numbers in parsable
.Pq exact
values.
.It Fl P
Display full paths for vdevs instead of only the last component of
the path.
This can be used in conjunction with the
.Fl L
flag.
.It Fl T Sy u Ns | Ns Sy d
Display a time stamp.
Specify
.Sy u
for a printed representation of the internal representation of time.
See
.Xr time 1 .
Specify
.Sy d
for standard date format.
See
.Xr date 1 .
.It Fl v
Verbose statistics.
Reports usage statistics for individual vdevs within the pool, in addition to
the pool-wide statistics.

.Sh EXAMPLES
.\" These are, respectively, examples 6, 15 from zpool.8
.\" Make sure to update them bidirectionally
.Ss Example 1 : No Listing Available ZFS Storage Pools
The following command lists all available pools on the system.
In this case, the pool
.Ar zion
is faulted due to a missing device.
The results from this command are similar to the following:
.Bd -literal -compact -offset Ds
.No # Nm zpool Cm 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 -
.Ed
.
.Ss Example 2 : No Displaying expanded space on a device
The following command displays the detailed information for the pool
.Ar 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.
