NAME

       tunegfs2 - View and manipulate gfs2 superblocks

SYNOPSIS

       tunegfs2 [OPTIONS] /dev/blockdevice

DESCRIPTION

       tunegfs2 allows viewing and manipulating the values contained in a GFS or GFS2 superblock.
       It is able to modify the UUID (on GFS2 only), label, lockproto and locktable.

       The values in the GFS2 superblock are read only on mount. Any changes on a live filesystem
       will  not  take  effect  until  the  next  time  it  is  mounted. Making changes on a live
       filesystem is not recommended for this reason.

OPTIONS

       -h

              Prints out usage information for this command.

       -l

              List contents of the filesystem superblock. Includes  the  current  values  of  the
              parameters that can be set by this program.

       -L <label>

              Change  the  filesystem  label.  Note  that  the  GFS2 filesystem label is also the
              locktable name.

       -o [lockproto=<proto>] [locktable=<table>]

              Set mount options. Currently supported options include lockproto and locktable

       -U <uuid>

              Set the filesystem UUID

       -V

              Print out the information on the version of the tool.
