|  | 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". |

|  | 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. |

|  | 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. | 
|  |  |

|  | 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. |

|  | performance of the filesystem. |
