Moved subcommand topics into individual manpages. Reordered and grouped the list of subcommands by topic. Moved concepts overview to `zpoolconcepts.8` and the long list of available pool properties to `zpoolprops.8`. Internal cross-references copied from `zpool.8` needed to be converted to `.Xr` external references to new subcommand manual pages. Move `autotrim` into lexical order, autotrim tacked onto the end of a list. Now it is in alphabetical order. Clarify attach/detach description. Description was too specific to command syntax. Overview clarifies reason for attaching or detaching a device. Clarify replace description, don't refer to subcommand arguments. Clarify split command description, say what split actually does and why you'd want to do it. Clarify description of upgrade, and simplify the zpool.8 wording of the zpool-upgrade(8) description. Clarify description of import, detail what zpool-import(8) actually does. Add appropriate SEE ALSO sections. Divided zpool subcommand manual pages need their own SEE ALSO sections. Also modified fsck.zfs.8 to point directly to zfs-scrub.8 and zed.8.in to include a direct reference to zfs-events.8 Reviewed-by: Matt Ahrens <matt@delphix.com> Reviewed-by: Kjeld Schouten <kjeld@schouten-lebbing.nl> Reviewed-by: Brian Behlendorf <behlendorf1@llnl.gov> Signed-off-by: Ross Williams <ross@ross-williams.net> Closes #9564

|
|
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.
|
|
When the primary pool storage includes a top-level raidz vdev only hot spare,
|
|
cache, and log devices can be removed.
|
|
.sp
|
|
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 IO 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 5 .
|
|
.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.
|
|
.Bl -tag -width Ds
|
|
.It Fl 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.
|
|
.El

|
.Bl -tag -width Ds
