NAME

       gfs2_jadd - Add journals to a GFS2 filesystem

SYNOPSIS

       gfs2_jadd [OPTION]... <DEVICE|MOINTPOINT>...

DESCRIPTION

       gfs2_jadd  is  used  to  add  journals  (and a few other per-node files) to a GFS2 filesystem.  When this
       operation is complete, the journal index is updated so that machines mounting the filesystem at  a  later
       date  will  see  the newly created journals in addition to the journals already there. Machines which are
       already running in the cluster are unaffected.

       You may only run gfs2_jadd on a mounted filesystem, addition of journals to unmounted filesystems is  not
       supported.   You  only need to run gfs2_jadd on one node in the cluster. All the other nodes will see the
       expansion has occurred when required.

       You must be superuser to execute gfs2_jadd. The gfs2_jadd tool tries to prevent you from corrupting  your
       filesystem by checking as many of the likely problems as it can. When growing a filesystem, only the last
       step of updating the journal index affects the currently mounted  filesystem  and  so  failure  part  way
       through the expansion process should leave your filesystem in its original state.

OPTIONS

       -c MegaBytes
              Initial size of each journal's quota change file

       -D     Print out debugging information about the filesystem layout.

       -h     Prints out a short usage message and exits.

       -J size
              The size of the new journals in megabytes. The defaults to 32MB (the minimum size allowed is 8MB).
              If you want to add journals of different sizes to the filesystem, you'll  need  to  run  gfs2_jadd
              once for each different size of journal.

       -j num The number of new journals to add.

       -q     Be quiet.  Don't print anything.

       -V     Version. Print version information, then exit.
