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.
39
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.
51
52config OCFS2_FS_STATS
53    bool "OCFS2 statistics"
54    depends on OCFS2_FS
55    default y
56    help
57      This option allows some fs statistics to be captured. Enabling
58      this option may increase the memory consumption.
59
60config OCFS2_DEBUG_MASKLOG
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.
69
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.
