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

Tools web page: https://github.com/markfasheh/ocfs2-tools
OCFS2 mailing lists: https://subspace.kernel.org/lists.linux.dev.html
For more information on OCFS2, see the file
<file:Documentation/filesystems/ocfs2.rst>.
config OCFS2_FS_O2CB
tristate "O2CB Kernelspace Clustering"
depends on OCFS2_FS
default y
help
OCFS2 includes a simple kernelspace clustering package, the OCFS2
Cluster Base. It only requires a very small userspace component
to configure it. This comes with the standard ocfs2-tools package.
O2CB is limited to maintaining a cluster for OCFS2 file systems.
It cannot manage any other cluster applications.
It is always safe to say Y here, as the clustering method is
run-time selectable.
config OCFS2_FS_USERSPACE_CLUSTER
tristate "OCFS2 Userspace Clustering"
depends on OCFS2_FS && DLM
default y
help
This option will allow OCFS2 to use userspace clustering services
in conjunction with the DLM in fs/dlm. If you are using a
userspace cluster manager, say Y here.
It is safe to say Y, as the clustering method is run-time
selectable.
config OCFS2_FS_STATS
bool "OCFS2 statistics"
depends on OCFS2_FS && DEBUG_FS
default y
help
This option allows some fs statistics to be captured. Enabling
this option may increase the memory consumption.
config OCFS2_DEBUG_MASKLOG
bool "OCFS2 logging support"
depends on OCFS2_FS
default y
help
The ocfs2 filesystem has an extensive logging system. The system
allows selection of events to log via files in /sys/o2cb/logmask/.
This option will enlarge your kernel, but it allows debugging of
ocfs2 filesystem issues.
config OCFS2_DEBUG_FS
bool "OCFS2 expensive checks"
depends on OCFS2_FS
default n
help
This option will enable expensive consistency checks. Enable
this option for debugging only as it is likely to decrease
performance of the filesystem.
