5.6. Adding Journals to a File System

The command is used to add journals to a GFS file system after the device
gfs_jadd
where the file system resides has been expanded. Running a
GFS file system uses space between the current end of the file system and the end of the
device where the file system resides. When the fill operation is completed, the journal index
is updated.
The command must be run on mounted file system, but it only needs to be run
gfs_jadd
on one node in the cluster. All the other nodes sense that the expansion has occurred.
