 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
+                       filesystem will not be damaged though, thanks to the

+                       will hurt performance, but it's good for data-safety.

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