9.6. 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 can only be run on a 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.
To verify that the changes were successful, you can use the
gfs_jadd
command with the
-T
(test) and
-v
(verbose) flags. Running the command with those flags displays the current state of the mounted
GFS file system.
