 preferred_slot=0(*)     During mount, try to use this filesystem slot first. If
                         it is in use by another node, the first empty one found
                         will be chosen. Invalid values will be ignored.
+commit=nrsec    (*)     Ocfs2 can be told to sync all its data and metadata
+                        every 'nrsec' seconds. The default value is 5 seconds.
+                        This means that if you lose your power, you will lose
+                        as much as the latest 5 seconds of work (your

+localalloc=8(*)         Allows custom localalloc size in MB. If the value is too
+                        large, the fs will silently revert it to the default.
