| 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". | |

| 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. | |

| 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 | ||

| 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. | |

| 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. |
