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. Run without any options, this command
       will print out information about the content of the superblock.

       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 infomration for this command.

       -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.
