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.

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 .Em filesystem due to the use of the .Fl o option. +.It Fl u +Do not mount the newly created file system. .It Fl v Print verbose information about the created dataset. .El .It Xo .Nm zfs .Cm create .Op Fl ps .Op Fl b Ar blocksize .Oo Fl o Ar property Ns = Ns Ar value Oc Ns ... .Fl V Ar size Ar volume .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 multiple of the .Sy blocksize . .Bl -tag -width "-b" .It Fl b Ar blocksize Equivalent to .Fl o Sy volblocksize Ns = Ns Ar blocksize . If this option is specified in conjunction with .Fl o Sy volblocksize , the resulting behavior is undefined. .It Fl o Ar property Ns = Ns Ar value Sets the specified property as if the .Nm zfs Cm set Ar property Ns = Ns Ar value command 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 s Creates a sparse volume with no reservation. See .Sy volsize in the .Em Native Properties section of .Xr zfsprops 8 for more information about sparse volumes. .It Fl n Do a dry-run .Pq Qq No-op creation. No datasets will be created.
