SYNOPSIS

10       tunegfs2 [OPTIONS] /dev/blockdevice

DESCRIPTION

14       tunegfs2  allows viewing and manipulating the values contained in a GFS
15       or GFS2 superblock. It is able to  modify  the  UUID  (on  GFS2  only),
16       label,  lockproto  and locktable. Run without any options, this command
17       will print out information about the content of the superblock.
18
19       The values in the GFS2 superblock are read only on mount.  Any  changes
20       on  a  live  filesystem  will not take effect until the next time it is
21       mounted. Making changes on a live filesystem  is  not  recommended  for
22       this reason.
