NAME
zpool-remove — remove devices from ZFS storage poolSYNOPSIS
| 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.
- zpool remove -s pool
- Stops and cancels an in-progress removal of a top-level vdev.
