| 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 |

| 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. |

| this option may increase the memory consumption. |

| 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 |

| 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. |
