- 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".

- 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

- 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.
