| 11 | OCFS2 is a general purpose extent based shared disk cluster file |
| 12 | system with many similarities to ext3. It supports 64 bit inode |
| 13 | numbers, and has automatically extending metadata groups which may |
| 14 | also make it attractive for non-clustered use. |
| 15 | |
| 16 | You'll want to install the ocfs2-tools package in order to at least |
| 17 | get "mount.ocfs2". |

| 27 | tristate "O2CB Kernelspace Clustering" |
| 28 | depends on OCFS2_FS |
| 29 | default y |
| 30 | help |
| 31 | OCFS2 includes a simple kernelspace clustering package, the OCFS2 |
| 32 | Cluster Base. It only requires a very small userspace component |
| 33 | to configure it. This comes with the standard ocfs2-tools package. |
| 34 | O2CB is limited to maintaining a cluster for OCFS2 file systems. |
| 35 | It cannot manage any other cluster applications. |
| 36 | |
| 37 | It is always safe to say Y here, as the clustering method is |
| 38 | run-time selectable. |

| 43 | default y |
| 44 | help |
| 45 | This option will allow OCFS2 to use userspace clustering services |
| 46 | in conjunction with the DLM in fs/dlm. If you are using a |
| 47 | userspace cluster manager, say Y here. |
| 48 | |
| 49 | It is safe to say Y, as the clustering method is run-time |

| 65 | The ocfs2 filesystem has an extensive logging system. The system |
| 66 | allows selection of events to log via files in /sys/o2cb/logmask/. |
| 67 | This option will enlarge your kernel, but it allows debugging of |
| 68 | ocfs2 filesystem issues. |

| 75 | This option will enable expensive consistency checks. Enable |
| 76 | this option for debugging only as it is likely to decrease |
| 77 | performance of the filesystem. |
