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

|
|

|

|

|
.Op Fl fw

|
.Op Fl o Ar property Ns = Ns Ar value
|
|
.Ar pool Ar device Op Ar new_device
|
|
.Xc
|
|
Replaces
|
|
.Ar old_device
|
|
with
|
|
.Ar new_device .
|
|
This is equivalent to attaching
|
|
.Ar new_device ,
|
|
waiting for it to resilver, and then detaching
|
|
.Ar old_device .
|
|
.Pp
|
|
The size of
|
|
.Ar new_device
|
|
must be greater than or equal to the minimum size of all the devices in a mirror
|
|
or raidz configuration.
|
|
.Pp
|
|
.Ar new_device
|
|
is required if the pool is not redundant.
|
|
If
|
|
.Ar new_device
|
|
is not specified, it defaults to
|
|
.Ar old_device .
|
|
This form of replacement is useful after an existing disk has failed and has
|
|
been physically replaced.
|
|
In this case, the new disk may have the same
|
|
.Pa /dev
|
|
path as the old device, even though it is actually a different disk.
|
|
ZFS recognizes this.
|
|
.Bl -tag -width Ds
|
|
.It Fl f
|
|
Forces use of
|
|
.Ar new_device ,
|
|
even if it appears to be in use.
|
|
Not all devices can be overridden in this manner.
|
|
.It Fl o Ar property Ns = Ns Ar value
|
|
Sets the given pool properties. See the
|
|
.Xr zpoolprops
|
|
manual page for a list of valid properties that can be set.
|
|
The only property supported at the moment is
|
|
.Sy ashift .
|
|
.It Fl w
|
|
Waits until the replacement has completed before returning.
