MOUNT_HAMMER2(8)       DragonFly System Manager's Manual      MOUNT_HAMMER2(8)

NAME
     mount_hammer2 - mount a HAMMER2 file system

SYNOPSIS
     mount_hammer2 [-o options] special[@label] node
     mount_hammer2 [-o options] @label node
     mount_hammer2 -u [-o options] node

DESCRIPTION
     The mount_hammer2 utility mounts a HAMMER2 file system backed by special
     file at mount point node.  PFS label is mounted.

     @label (no special) is a short form, which mounts label from an already
     mounted HAMMER2 filesystem.  If there are multiple mounts with the same
     label, the first one mounted takes precedence over others.

     Default value for label is based on partition of special: `a' defaults to
     "BOOT" , `d' defaults to "ROOT", and any other partition defaults to
     "DATA".

     The options are as follows:

     -o options
             Options are specified with a -o flag followed by a comma
             separated string of options.  See the mount(8) man page for
             possible options and their meanings.  The following HAMMER2
             specific options are also available:

             local   Disable PFS clustering.

     -u      Update the mount point.  This is used to upgrade a mount to read-
             write.

EXIT STATUS
     The mount_hammer2 utility exits 0 on success, and >0 if an error occurs.

EXAMPLES
     Mount a HAMMER2 file system on /mnt, PFS "ROOT" is mounted:

           mount_hammer2 /dev/da0s1d /mnt

     A corresponding fstab(5) entry is:

           /dev/da0s1d /mnt hammer2

     Mount PFS "TEST" from same filesystem:

           mount_hammer2 @TEST /mnt2
