gfs2_jadd - Add journals to a GFS2 filesystem
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
- Print out debugging information about the filesystem layout.
- Prints out a short usage message and exits.
- -J size
- The size of the new journals in megabytes. The defaults to 32MB (theminimum size allowed is 8MB). If you want to add journals of differentsizes to the filesystem, you'll need to run gfs2_jadd once for eachdifferent size of journal.
- -j num
- The number of new journals to add.
- Be quiet. Don't print anything.
- Version. Print version information, then exit.
