0011 OCFS2 is a general purpose extent based shared disk cluster file
0012 system with many similarities to ext3. It supports 64 bit inode
0013 numbers, and has automatically extending metadata groups which may
0014 also make it attractive for non-clustered use.
0015
0016 You'll want to install the ocfs2-tools package in order to at least
0017 get "mount.ocfs2".

0028 depends on OCFS2_FS
0029 default y
0030 help
0031 OCFS2 includes a simple kernelspace clustering package, the OCFS2
0032 Cluster Base. It only requires a very small userspace component
0033 to configure it. This comes with the standard ocfs2-tools package.
0034 O2CB is limited to maintaining a cluster for OCFS2 file systems.
0035 It cannot manage any other cluster applications.
0036
0037 It is always safe to say Y here, as the clustering method is
0038 run-time selectable.

0044 help
0045 This option will allow OCFS2 to use userspace clustering services
0046 in conjunction with the DLM in fs/dlm. If you are using a
0047 userspace cluster manager, say Y here.
0048
0049 It is safe to say Y, as the clustering method is run-time

0065 The ocfs2 filesystem has an extensive logging system. The system
0066 allows selection of events to log via files in /sys/o2cb/logmask/.
0067 This option will enlarge your kernel, but it allows debugging of
0068 ocfs2 filesystem issues.

0075 This option will enable expensive consistency checks. Enable
0076 this option for debugging only as it is likely to decrease
0077 performance of the filesystem.
