You need to increase the size of the device before doing gfs_jadd. Don't make the mistake of running gfs_grow immediately because that will consume your new storage for file system space and still leave you no room for any new journals. Only run gfs_grow after you've added the journals you need. We eliminated the problem in GFS2, so another option would be to use gfs2_convert to convert the file system to GFS2 and then use gfs2_jadd. Of course, GFS2 and gfs2_convert are still pretty new, so they carry a certain amount of risk, as with all new software. Some old versions of gfs2_convert had bad problems, so if you want to go this route, make sure you make a current backup before you do anything. Second, make sure you gfs_fsck before you convert so that your file system is consistent before running gfs2_convert. Third, make sure you have the latest and greatest gfs2_convert, so if you're on RHEL5.3, for example, make sure you've got all the latest z-stream updates. If you build from source, make sure you compile from the most recent source code.
