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". Project web page: https://ocfs2.wiki.kernel.org/ 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.
