2 tristate "OCFS2 file system support"
3 depends on NET && SYSFS && CONFIGFS_FS
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.
15 You'll want to install the ocfs2-tools package in order to at least

26 tristate "O2CB Kernelspace Clustering"
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.
36 It is always safe to say Y here, as the clustering method is
39 config OCFS2_FS_USERSPACE_CLUSTER
40 tristate "OCFS2 Userspace Clustering"
41 depends on OCFS2_FS && DLM
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.
48 It is safe to say Y, as the clustering method is run-time
52 bool "OCFS2 statistics"
53 depends on OCFS2_FS && DEBUG_FS
56 This option allows some fs statistics to be captured. Enabling
57 this option may increase the memory consumption.
59 config OCFS2_DEBUG_MASKLOG
60 bool "OCFS2 logging support"
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.
70 bool "OCFS2 expensive checks"
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.
