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

			journaling).  This default value (or any low value)

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

			Setting it to 0 will have the same effect as leaving

			it at the default (5 seconds).

			Setting it to very large values will improve

			performance.

localalloc=8(*)		Allows custom localalloc size in MB. If the value is too

			large, the fs will silently revert it to the default.

			Localalloc is not enabled for local mounts.

localflocks		This disables cluster aware flock.
