 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.
 14 
 15           You'll want to install the ocfs2-tools package in order to at least
 16           get "mount.ocfs2".

 25 config OCFS2_FS_O2CB

 29         help
 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.
 35 
 36           It is always safe to say Y here, as the clustering method is
 37           run-time selectable.

 39 config OCFS2_FS_USERSPACE_CLUSTER
 40         tristate "OCFS2 Userspace Clustering"

 42         default y
 43         help
 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.
 47 
 48           It is safe to say Y, as the clustering method is run-time
 49           selectable.

 51 config OCFS2_FS_STATS

 55         help
 56           This option allows some fs statistics to be captured. Enabling
 57           this option may increase the memory consumption.

 62         default y
 63         help
 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.
 68 
 69 config OCFS2_DEBUG_FS
 70         bool "OCFS2 expensive checks"
 71         depends on OCFS2_FS
 72         default n
 73         help
 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.
