NAME

     zfs-create — create ZFS dataset

SYNOPSIS

     zfs create [-Pnpuv] [-o property=value]… filesystem
     zfs create [-ps] [-b blocksize] [-o property=value]… -V size volume

DESCRIPTION

     zfs create [-Pnpuv] [-o property=value]… filesystem
       Creates a new ZFS file system.  The file system is automatically mounted according to the mountpoint
       property inherited from the parent, unless the -u option is used.

       -o property=value
           Sets the specified property as if the command zfs set property=value was invoked at the same time the
           dataset was created.  Any editable ZFS property can also be set at creation time.  Multiple -o
           options can be specified.  An error results if the same property is specified in multiple -o options.

       -p  Creates all the non-existing parent datasets.  Datasets created in this manner are automatically
           mounted according to the mountpoint property inherited from their parent.  Any property specified on
           the command line using the -o option is ignored.  If the target filesystem already exists, the
           operation completes successfully.

       -n  Do a dry-run ("No-op") creation.  No datasets will be created.  This is useful in conjunction with
           the -v or -P flags to validate properties that are passed via -o options and those implied by other
           options.  The actual dataset creation can still fail due to insufficient privileges or available
           capacity.

       -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 create_ancestors and create keys have
           filesystem as their only value.  The create_ancestors key only appears if the -p option is used.  The
           property key has two values, a property name that property's value.  The property key may appear zero
           or more times, once for each property that will be set local to filesystem due to the use of the -o
           option.

       -u  Do not mount the newly created file system.

       -v  Print verbose information about the created dataset.

     zfs create [-ps] [-b blocksize] [-o property=value]… -V size volume
       Creates a volume of the given size.  The volume is exported as a block device in /dev/zvol/path, where
       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.

       size is automatically rounded up to the nearest multiple of the blocksize.

       -b blocksize
           Equivalent to -o volblocksize=blocksize.  If this option is specified in conjunction with -o
           volblocksize, the resulting behavior is undefined.

       -o property=value
           Sets the specified property as if the zfs set property=value command was invoked at the same time the
           dataset was created.  Any editable ZFS property can also be set at creation time.  Multiple -o
           options can be specified.  An error results if the same property is specified in multiple -o options.

       -p  Creates all the non-existing parent datasets.  Datasets created in this manner are automatically
           mounted according to the mountpoint property inherited from their parent.  Any property specified on
           the command line using the -o option is ignored.  If the target filesystem already exists, the
           operation completes successfully.

       -s  Creates a sparse volume with no reservation.  See volsize in the Native Properties section of
           zfsprops(7) for more information about sparse volumes.

       -n  Do a dry-run ("No-op") creation.  No datasets will be created.  This is useful in conjunction with
           the -v or -P flags to validate properties that are passed via -o options and those implied by other
           options.  The actual dataset creation can still fail due to insufficient privileges or available
           capacity.

       -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 create_ancestors and create keys have volume
           as their only value.  The create_ancestors key only appears if the -p option is used.  The property
           key has two values, a property name that property's value.  The property key may appear zero or more
           times, once for each property that will be set local to volume due to the use of the -b or -o
           options, as well as refreservation if the volume is not sparse.

       -v  Print verbose information about the created dataset.

   ZFS Volumes as Swap
     ZFS volumes may be used as swap devices.  After creating the volume with the zfs create -V enable the swap
     area using the swapon(8) command.  Swapping to files on ZFS filesystems is not supported.
