5.6. Adding Journals to a File System
The
gfs_jadd
command is used to add journals to a GFS file system after the device
where the file system resides has been expanded. Running a
gfs_jadd
command on 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
gfs_jadd
command must be run on mounted file system, but it only needs to be run
on one node in the cluster. All the other nodes sense that the expansion has occurred.
