Most subcommands got their own manpages (e.g. create). Some related commands grouped into a single manpage and symlinks created (e.g. set, get, and inherit). I did this when topics were either too short to warrant their own file or so interrelated that a user would want to refer between commands in the same file. Corrected .Sx internal references to .Xr cross refs; lots of .Sx references from when text was all in zfs.8 needed to be changed to .Xr zfs-$SUBCOMMAND 8 cross references. Divided subcommand list in zfs(8) into sections of related functionality. This required writing new descriptions for some commands. Preserved ".Os Linux", `.Os` macro parsing behavior differs between mandoc from the "BSD" mandoc package (available on Ubuntu) and man from Ubuntu's man-db package, which calls groff to format the manpages. Groff handles the `.Os` macro differently and wrongly, defaulting it to "BSD" in `/usr/share/groff/*/tmac/mdoc/doc-common`, instead of getting the default from `uname`. A future set of changes will introduce build-time preprocessing of manpages for platform-specific documentation and can insert the correct operating system name. Added SEE ALSO sections, the newly-divided zfs-*.8 subcommand man pages needed their own SEE ALSO sections pointing to related subcommands and, in some cases, documentation from other packages (e.g. zfs-share.8).

|
|
Creates a new ZFS file system.
|
|
The file system is automatically mounted according to the
|
|
.Sy mountpoint
|
|
property inherited from the parent.
|
|
.Bl -tag -width "-o"
|
|
.It Fl o Ar property Ns = Ns Ar value
|
|
Sets the specified property as if the command
|
|
.Nm zfs Cm set Ar property Ns = Ns Ar value
|
|
was invoked at the same time the dataset was created.
|
|
Any editable ZFS property can also be set at creation time.
|
|
Multiple
|
|
.Fl o
|
|
options can be specified.
|
|
An error results if the same property is specified in multiple
|
|
.Fl o
|
|
options.
|
|
.It Fl p
|
|
Creates all the non-existing parent datasets.
|
|
Datasets created in this manner are automatically mounted according to the
|
|
.Sy mountpoint
|
|
property inherited from their parent.
|
|
Any property specified on the command line using the
|
|
.Fl o
|
|
option is ignored.
|
|
If the target filesystem already exists, the operation completes successfully.
|
|
.It Fl n
|
|
Do a dry-run
|
|
.Pq Qq No-op
|
|
creation.
|
|
No datasets will be created.
|
|
This is useful in conjunction with the
|
|
.Fl v
|
|
or
|
|
.Fl P
|
|
flags to validate properties that are passed via
|
|
.Fl o
|
|
options and those implied by other options.
|
|
The actual dataset creation can still fail due to insufficient privileges or
|
|
available capacity.
|
|
.It Fl P
|
|
Print machine-parsable verbose information about the created dataset.
|
|
Each line of output contains a key and one or two values, all separated by tabs.
|
|
The
|
|
.Sy create_ancestors
|
|
and
|
|
.Sy create
|
|
keys have
|
|
.Em filesystem
|
|
as their only value.
|
|
The
|
|
.Sy create_ancestors
|
|
key only appears if the
|
|
.Fl p
|
|
option is used.
|
|
The
|
|
.Sy property
|
|
key has two values, a property name that property's value.
|
|
The
|
|
.Sy property
|
|
key may appear zero or more times, once for each property that will be set local
|
|
to

|
|
due to the use of the

.Xc
|
|
Creates a volume of the given size.
|
|
The volume is exported as a block device in
|
|
.Pa /dev/zvol/path ,
|
|
where
|
|
.Em path
|
|
is the name of the volume in the ZFS namespace.
|
|
The size represents the logical size as exported by the device.
|
|
By default, a reservation of equal size is created.
|
|
.Pp
|

.Ar size
|
|
is automatically rounded up to the nearest 128 Kbytes to ensure that the volume
|
|
has an integral number of blocks regardless of

Equivalent to

the resulting behavior is undefined.

.Ss ZFS Volumes as Swap
|
|
ZFS volumes may be used as swap devices. After creating the volume with the

.Xr mkswap 8
|
|
and
|
|
.Xr swapon 8
|
|
commands. Do not swap to a file on a ZFS file system. A ZFS swap file
|
