Property to allow sets of features to be specified; for compatibility with specific versions / releases / external systems. Influences the behavior of 'zpool upgrade' and 'zpool create'. Initial man page changes and test cases included. Brief synopsis: zpool create -o compatibility=off|legacy|file[,file...] pool vdev... compatibility = off : disable compatibility mode (enable all features) compatibility = legacy : request that no features be enabled compatibility = file[,file...] : read features from specified files. Only features present in *all* files will be enabled on the resulting pool. Filenames may be absolute, or relative to /etc/zfs/compatibility.d or /usr/share/zfs/compatibility.d (/etc checked first). Only affects zpool create, zpool upgrade and zpool status. ABI changes in libzfs: * New function "zpool_load_compat" to load and parse compat sets. * Add "zpool_compat_status_t" typedef for compatibility parse status. * Add ZPOOL_PROP_COMPATIBILITY to the pool properties enum * Add ZPOOL_STATUS_COMPATIBILITY_ERR to the pool status enum An initial set of base compatibility sets are included in cmd/zpool/compatibility.d, and the Makefile for cmd/zpool is modified to install these in $pkgdatadir/compatibility.d and to create symbolic links to a reasonable set of aliases.

|
|
Creates a new storage pool containing the virtual devices specified on the
|
|
command line.
|
|
The pool name must begin with a letter, and can only contain
|
|
alphanumeric characters as well as underscore
|
|
.Pq Qq Sy _ ,
|
|
dash
|
|
.Pq Qq Sy \&- ,
|
|
colon
|
|
.Pq Qq Sy \&: ,
|
|
space
|
|
.Pq Qq Sy \&\ ,
|
|
and period
|
|
.Pq Qq Sy \&. .
|
|
The pool names
|
|
.Sy mirror ,
|
|
.Sy raidz ,
|
|
.Sy draid ,
|
|
.Sy spare
|
|
and
|
|
.Sy log
|
|
are reserved, as are names beginning with
|
|
.Sy mirror ,
|
|
.Sy raidz ,
|
|
.Sy draid ,
|
|
.Sy spare ,
|
|
and the pattern
|
|
.Sy c[0-9] .
|
|
The
|
|
.Ar vdev
|
|
specification is described in the
|
|
.Em Virtual Devices
|
|
section of
|
|
.Xr zpoolconcepts.
|
|
.Pp
|
|
The command attempts to verify that each device specified is accessible and not
|
|
currently in use by another subsystem. However this check is not robust enough
|
|
to detect simultaneous attempts to use a new device in different pools, even if
|
|
.Sy multihost
|
|
is
|
|
.Sy enabled.
|
|
The
|
|
administrator must ensure that simultaneous invocations of any combination of
|
|
.Sy zpool replace ,
|
|
.Sy zpool create ,
|
|
.Sy zpool add ,
|
|
or
|
|
.Sy zpool labelclear ,
|
|
do not refer to the same device. Using the same device in two pools will
|
|
result in pool corruption.
|
|
.Pp
|
|
There are some uses, such as being currently mounted, or specified as the
|
|
dedicated dump device, that prevents a device from ever being used by ZFS.
|
|
Other uses, such as having a preexisting UFS file system, can be overridden with
|
|
the
|
|
.Fl f
|
|
option.
|
|
.Pp
|
|
The command also checks that the replication strategy for the pool is
|
|
consistent.
|
|
An attempt to combine redundant and non-redundant storage in a single pool, or
|
|
to mix disks and files, results in an error unless
|
|
.Fl f
|
|
is specified.
|
|
The use of differently sized devices within a single raidz or mirror group is
|
|
also flagged as an error unless
|
|
.Fl f
|
|
is specified.
|
|
.Pp
|
|
Unless the
|
|
.Fl R
|
|
option is specified, the default mount point is
|
|
.Pa / Ns Ar pool .
|
|
The mount point must not exist or must be empty, or else the root dataset
|
|
cannot be mounted.
|
|
This can be overridden with the
|
|
.Fl m
|
|
option.
|
|
.Pp
|
|
By default all supported features are enabled on the new pool. The
|
|
.Fl d
|
|
option or the
|
|
.Fl o Ar compatibility
|
|
property (eg:
|
|
.Fl o Ar compatibility=2020
|
|
) can be used to restrict the features that are enabled, so that the
|
|
pool can be imported on other releases of the ZFS software.
|
|
.Bl -tag -width Ds
|
|
.It Fl d
|
|
Do not enable any features on the new pool.
|
|
Individual features can be enabled by setting their corresponding properties to
|
|
.Sy enabled
|
|
with the
|
|
.Fl o
|
|
option.
|
|
See
|
|
.Xr zpool-features 5
|
|
for details about feature properties.
|
|
.It Fl f
|
|
Forces use of
|
|
.Ar vdev Ns s ,
|
|
even if they appear in use or specify a conflicting replication level.
|
|
Not all devices can be overridden in this manner.
|
|
.It Fl m Ar mountpoint
|
|
Sets the mount point for the root dataset.
|
|
The default mount point is
|
|
.Pa /pool
|
|
or
|
|
.Pa altroot/pool
|
|
if
|
|
.Ar altroot
|
|
is specified.
|
|
The mount point must be an absolute path,
|
|
.Sy legacy ,
|
|
or
|
|
.Sy none .
|
|
For more information on dataset mount points, see
|
|
.Xr zfs 8 .
|
|
.It Fl n
|
|
Displays the configuration that would be used without actually creating the
|
|
pool.
|
|
The actual pool creation can still fail due to insufficient privileges or
|
|
device sharing.
|
|
.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.
|
|
.It Fl o Ar compatibility Ns = Ns Ar off | legacy | file Bq , Ns Ar file Ns ...
|
|
Specifies compatibility feature sets. See
|
|
.Xr zpool-features 5
|
|
for more information about compatibility feature sets.
|
|
.It Fl o Ar feature@feature Ns = Ns Ar value
|
|
Sets the given pool feature. See the
|
|
.Xr zpool-features 5
|
|
section for a list of valid features that can be set.
|
|
Value can be either disabled or enabled.
|
|
.It Fl O Ar file-system-property Ns = Ns Ar value
|
|
Sets the given file system properties in the root file system of the pool.
|
|
See the
|
|
.Xr zfsprops 8
|
|
manual page for a list of valid properties that can be set.
|
|
.It Fl R Ar root
|
|
Equivalent to
|
|
.Fl o Sy cachefile Ns = Ns Sy none Fl o Sy altroot Ns = Ns Ar root
|
|
.It Fl t Ar tname
|
|
Sets the in-core pool name to
|
|
.Sy tname
|
|
while the on-disk name will be the name specified as the pool name
|
|
.Sy pool .
|
|
This will set the default cachefile property to none. This is intended
|
|
to handle name space collisions when creating pools for other systems,
|
|
such as virtual machines or physical machines whose pools live on network
|
|
block devices.
