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

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

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

57	  This option allows some fs statistics to be captured. Enabling
58	  this option may increase the memory consumption.

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

70config OCFS2_DEBUG_FS

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