|
|
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.
|
|
.Pp
|
|
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.
|
|
.Pp
|
|
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
|
|
.Nm zpool Cm remove
|
|
command initiates the removal and returns, while the evacuation continues in
|
|
the background.
|
|
The removal progress can be monitored with
|
|
.Nm zpool Cm status .
|
|
If an I/O error is encountered during the removal process it will be cancelled.
|
|
The
|
|
.Sy device_removal
|
|
feature flag must be enabled to remove a top-level vdev, see
|
|
.Xr zpool-features 7 .
|
|
.Pp
|
|
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
|
|
.Nm zpool Cm detach
|
|
command.

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.
