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".

26config OCFS2_FS_O2CB
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.

40config OCFS2_FS_USERSPACE_CLUSTER
41 tristate "OCFS2 Userspace Clustering"
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.

52config OCFS2_FS_STATS

55 default y
56 help
57 This option allows some fs statistics to be captured. Enabling
58 this option may increase the memory consumption.

61 bool "OCFS2 logging support"
62 depends on OCFS2_FS
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
71 bool "OCFS2 expensive checks"
72 depends on OCFS2_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.
