If the .Fl d or .Fl c options are not specified, this command searches for devices using libblkid on Linux and geom on .Fx . The .Fl d option can be specified multiple times, and all directories are searched. If the device appears to be part of an exported pool, this command displays a summary of the pool with the name of the pool, a numeric identifier, as well as the vdev layout and current health of the device for each device or file. Destroyed pools, pools that were previously destroyed with the .Nm zpool Cm destroy command, are not listed unless the .Fl D option is specified. .Pp The numeric identifier is unique, and can be used instead of the pool name when multiple exported pools of the same name are available. .Bl -tag -width Ds .It Fl c Ar cachefile Reads configuration from the given .Ar cachefile that was created with the .Sy cachefile pool property.

This option is ignored if the pool is importable or already imported. .It Fl l Indicates that this command will request encryption keys for all encrypted datasets it attempts to mount as it is bringing the pool online. Note that if any datasets have a .Sy keylocation of .Sy prompt this command will block waiting for the keys to be entered. Without this flag encrypted datasets will be left unavailable until the keys are loaded. .It Fl m Allows a pool to import when there is a missing log device.

Once the pool is imported with this flag there is no way to undo the rewind. All changes and data that were written after the checkpoint are lost! The only exception is when the .Sy readonly mounting option is enabled. In this case, the checkpointed state of the pool is opened and an administrator can see how the pool would look like if they were to fully rewind. .It Fl s Scan using the default search path, the libblkid cache will not be consulted.

A storage pool is a collection of devices that provides physical storage and data replication for ZFS datasets. All datasets within a storage pool share the same space. See .Xr zfs 8 for information on managing datasets. .Pp For an overview of creating and managing ZFS storage pools see the .Xr zpoolconcepts 7 manual page. . .Sh SUBCOMMANDS All subcommands that modify state are logged persistently to the pool in their original form. .Pp The .Nm command provides subcommands to create and destroy storage pools, add capacity to storage pools, and provide information about the storage pools. The following subcommands are supported: .Bl -tag -width Ds .It Xo .Nm .Fl ?\& .Xc Displays a help message. .It Xo .Nm .Fl V , -version .Xc .It Xo .Nm .Cm version .Xc Displays the software version of the .Nm userland utility and the ZFS kernel module. .El . .Ss Creation .Bl -tag -width Ds .It Xr zpool-create 8 Creates a new storage pool containing the virtual devices specified on the command line. .It Xr zpool-initialize 8 Begins initializing by writing to all unallocated regions on the specified devices, or all eligible devices in the pool if no individual devices are specified. .El . .Ss Destruction .Bl -tag -width Ds .It Xr zpool-destroy 8 Destroys the given pool, freeing up any devices for other use. .It Xr zpool-labelclear 8 Removes ZFS label information from the specified .Ar device . .El . .Ss Virtual Devices .Bl -tag -width Ds .It Xo .Xr zpool-attach 8 Ns / Ns Xr zpool-detach 8 .Xc Increases or decreases redundancy by .Cm attach Ns ing or .Cm detach Ns ing a device on an existing vdev (virtual device). .It Xo .Xr zpool-add 8 Ns / Ns Xr zpool-remove 8 .Xc Adds the specified virtual devices to the given pool, or removes the specified device from the pool. .It Xr zpool-replace 8 Replaces an existing device (which may be faulted) with a new one. .It Xr zpool-split 8 Creates a new pool by splitting all mirrors in an existing pool (which decreases its redundancy). .El . .Ss Properties Available pool properties listed in the .Xr zpoolprops 7 manual page. .Bl -tag -width Ds .It Xr zpool-list 8 Lists the given pools along with a health status and space usage. .It Xo .Xr zpool-get 8 Ns / Ns Xr zpool-set 8 .Xc Retrieves the given list of properties .Po or all properties if .Sy all is used .Pc for the specified storage pool(s). .El . .Ss Monitoring .Bl -tag -width Ds .It Xr zpool-status 8 Displays the detailed health status for the given pools. .It Xr zpool-iostat 8 Displays logical I/O statistics for the given pools/vdevs. Physical I/O operations may be observed via .Xr iostat 1 . .It Xr zpool-events 8 Lists all recent events generated by the ZFS kernel modules. These events are consumed by the .Xr zed 8 and used to automate administrative tasks such as replacing a failed device with a hot spare. That manual page also describes the subclasses and event payloads that can be generated. .It Xr zpool-history 8 Displays the command history of the specified pool(s) or all pools if no pool is specified. .El . .Ss Maintenance .Bl -tag -width Ds .It Xr zpool-scrub 8 Begins a scrub or resumes a paused scrub. .It Xr zpool-checkpoint 8 Checkpoints the current state of .Ar pool , which can be later restored by .Nm zpool Cm import Fl -rewind-to-checkpoint . .It Xr zpool-trim 8 Initiates an immediate on-demand TRIM operation for all of the free space in a pool. This operation informs the underlying storage devices of all blocks in the pool which are no longer allocated and allows thinly provisioned devices to reclaim the space. .It Xr zpool-sync 8 This command forces all in-core dirty data to be written to the primary pool storage and not the ZIL. It will also update administrative information including quota reporting. Without arguments, .Nm zpool Cm sync will sync all pools on the system. Otherwise, it will sync only the specified pool(s). .It Xr zpool-upgrade 8 Manage the on-disk format version of storage pools. .It Xr zpool-wait 8 Waits until all background activity of the given types has ceased in the given pool. .El . .Ss Fault Resolution .Bl -tag -width Ds .It Xo .Xr zpool-offline 8 Ns / Ns Xr zpool-online 8 .Xc Takes the specified physical device offline or brings it online. .It Xr zpool-resilver 8 Starts a resilver.
