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

25config OCFS2_FS_O2CB
26	tristate "O2CB Kernelspace Clustering"
27	depends on OCFS2_FS
28	default y
29	help
30	  OCFS2 includes a simple kernelspace clustering package, the OCFS2
31	  Cluster Base.  It only requires a very small userspace component
32	  to configure it. This comes with the standard ocfs2-tools package.
33	  O2CB is limited to maintaining a cluster for OCFS2 file systems.
34	  It cannot manage any other cluster applications.
35
36	  It is always safe to say Y here, as the clustering method is
37	  run-time selectable.
38
39config OCFS2_FS_USERSPACE_CLUSTER
40	tristate "OCFS2 Userspace Clustering"
41	depends on OCFS2_FS && DLM
42	default y
43	help
44	  This option will allow OCFS2 to use userspace clustering services
45	  in conjunction with the DLM in fs/dlm.  If you are using a
46	  userspace cluster manager, say Y here.
47
48	  It is safe to say Y, as the clustering method is run-time
49	  selectable.

51config OCFS2_FS_STATS
52	bool "OCFS2 statistics"
53	depends on OCFS2_FS && DEBUG_FS
54	default y
55	help
56	  This option allows some fs statistics to be captured. Enabling
57	  this option may increase the memory consumption.
58
59config OCFS2_DEBUG_MASKLOG
60	bool "OCFS2 logging support"
61	depends on OCFS2_FS
62	default y
63	help
64	  The ocfs2 filesystem has an extensive logging system.  The system
65	  allows selection of events to log via files in /sys/o2cb/logmask/.
66	  This option will enlarge your kernel, but it allows debugging of
67	  ocfs2 filesystem issues.
68
69config OCFS2_DEBUG_FS
70	bool "OCFS2 expensive checks"
71	depends on OCFS2_FS
72	default n
73	help
74	  This option will enable expensive consistency checks. Enable
75	  this option for debugging only as it is likely to decrease
76	  performance of the filesystem.
