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.
