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-nodefiles) to a GFS2 filesystem. When this operation is complete, thejournal index is updated so that machines mounting the filesystem at alater date will see the newly created journals in addition to thejournals already there. Machines which are already running in thecluster are unaffected.

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

You must be superuser to execute gfs2_jadd. The gfs2_jaddtool tries to prevent you from corrupting your filesystem by checkingas many of the likely problems as it can. When growing a filesystem,only the last step of updating the journal index affects the currentlymounted filesystem and so failure part way through the expansionprocess should leave your filesystem in its original state.

-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.
