......@@ -23,6 +23,15 @@ resize=value Resize the volume to <value> blocks. JFS only supports
read-write. The resize keyword with no value will grow
the volume to the full size of the partition.
nointegrity Do not write to the journal. The primary use of this option
is to allow for higher performance when restoring a volume
from backup media. The integrity of the volume is not
guaranteed if the system abnormally abends.
integrity Default. Commit metadata changes to the journal. Use this
option to remount a volume where the nointegrity option was
previously specified in order to restore normal behavior.
