ZPOOL-REMOVE(8)         FreeBSD System Manager's Manual        ZPOOL-REMOVE(8)

NAME
     zpool-remove - remove devices from ZFS storage pool

SYNOPSIS
     zpool remove [-npw] pool device<?>
     zpool remove -s pool

DESCRIPTION
     zpool remove [-npw] pool device<?>
             Removes the specified device from the pool.  This command
             supports removing hot spare, cache, log, and both mirrored and
             non-redundant primary top-level vdevs, including dedup and
             special vdevs.

             Top-level vdevs can only be removed if the primary pool storage
             does not contain a top-level raidz vdev, all top-level vdevs have
             the same sector size, and the keys for all encrypted datasets are
             loaded.

             Removing a top-level vdev reduces the total amount of space in
             the storage pool.  The specified device will be evacuated by
             copying all allocated space from it to the other devices in the
             pool.  In this case, the zpool remove command initiates the
             removal and returns, while the evacuation continues in the
             background.  The removal progress can be monitored with zpool
             status.  If an IO error is encountered during the removal process
             it will be cancelled.  The device_removal feature flag must be
             enabled to remove a top-level vdev, see zpool-features(7).

             A mirrored top-level device (log or data) can be removed by
             specifying the top-level mirror for the same.  Non-log devices or
             data devices that are part of a mirrored configuration can be
             removed using the zpool detach command.

             -n      Do not actually perform the removal ("No-op").  Instead,
                     print the estimated amount of memory that will be used by
                     the mapping table after the removal completes.  This is
                     nonzero only for top-level vdevs.

             -p      Used in conjunction with the -n flag, displays numbers as
                     parsable (exact) values.

             -w      Waits until the removal has completed before returning.

     zpool remove -s pool
             Stops and cancels an in-progress removal of a top-level vdev.
