remove
[-npw]
pool deviceâ¦
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
command initiates the removal and returns, while the evacuation continues in
the background.
The removal progress can be monitored with
zpool.
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
command.
