12	  OCFS2 is a general purpose extent based shared disk cluster file
13	  system with many similarities to ext3. It supports 64 bit inode
14	  numbers, and has automatically extending metadata groups which may
15	  also make it attractive for non-clustered use.
16
17	  You'll want to install the ocfs2-tools package in order to at least
18	  get "mount.ocfs2".

29	depends on OCFS2_FS
30	default y
31	help
32	  OCFS2 includes a simple kernelspace clustering package, the OCFS2
33	  Cluster Base.  It only requires a very small userspace component
34	  to configure it. This comes with the standard ocfs2-tools package.
35	  O2CB is limited to maintaining a cluster for OCFS2 file systems.
36	  It cannot manage any other cluster applications.
37
38	  It is always safe to say Y here, as the clustering method is
39	  run-time selectable.

43	depends on OCFS2_FS && DLM
44	default y
45	help
46	  This option will allow OCFS2 to use userspace clustering services
47	  in conjunction with the DLM in fs/dlm.  If you are using a
48	  userspace cluster manager, say Y here.
49
50	  It is safe to say Y, as the clustering method is run-time
51	  selectable.

59	  this option may increase the memory consumption.

64	default y
65	help
66	  The ocfs2 filesystem has an extensive logging system.  The system
67	  allows selection of events to log via files in /sys/o2cb/logmask/.
68	  This option will enlarge your kernel, but it allows debugging of
69	  ocfs2 filesystem issues.

74	default n
75	help
76	  This option will enable expensive consistency checks. Enable
77	  this option for debugging only as it is likely to decrease
78	  performance of the filesystem.
