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

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
