 13           OCFS2 is a general purpose extent based shared disk cluster file
 14           system with many similarities to ext3. It supports 64 bit inode
 15           numbers, and has automatically extending metadata groups which may
 16           also make it attractive for non-clustered use.
 17 
 18           You'll want to install the ocfs2-tools package in order to at least
 19           get "mount.ocfs2".

 28 config OCFS2_FS_O2CB
 29         tristate "O2CB Kernelspace Clustering"
 30         depends on OCFS2_FS
 31         default y
 32         help
 33           OCFS2 includes a simple kernelspace clustering package, the OCFS2
 34           Cluster Base.  It only requires a very small userspace component
 35           to configure it. This comes with the standard ocfs2-tools package.
 36           O2CB is limited to maintaining a cluster for OCFS2 file systems.
 37           It cannot manage any other cluster applications.
 38 
 39           It is always safe to say Y here, as the clustering method is
 40           run-time selectable.
 41 
 42 config OCFS2_FS_USERSPACE_CLUSTER
 43         tristate "OCFS2 Userspace Clustering"

 45         default y
 46         help
 47           This option will allow OCFS2 to use userspace clustering services
 48           in conjunction with the DLM in fs/dlm.  If you are using a
 49           userspace cluster manager, say Y here.
 50 
 51           It is safe to say Y, as the clustering method is run-time
 52           selectable.

 54 config OCFS2_FS_STATS
 55         bool "OCFS2 statistics"
 56         depends on OCFS2_FS && DEBUG_FS
 57         default y
 58         help
 59           This option allows some fs statistics to be captured. Enabling
 60           this option may increase the memory consumption.
 61 
 62 config OCFS2_DEBUG_MASKLOG
 63         bool "OCFS2 logging support"
 64         depends on OCFS2_FS
 65         default y
 66         help
 67           The ocfs2 filesystem has an extensive logging system.  The system
 68           allows selection of events to log via files in /sys/o2cb/logmask/.
 69           This option will enlarge your kernel, but it allows debugging of
 70           ocfs2 filesystem issues.
 71 
 72 config OCFS2_DEBUG_FS
 73         bool "OCFS2 expensive checks"
 74         depends on OCFS2_FS
 75         default n
 76         help
 77           This option will enable expensive consistency checks. Enable
 78           this option for debugging only as it is likely to decrease
 79           performance of the filesystem.
