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.
