  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. You'll want to install the ocfs2-tools package in order to at least
  16. get "mount.ocfs2".

  26. help
  27. OCFS2 includes a simple kernelspace clustering package, the OCFS2
  28. Cluster Base. It only requires a very small userspace component
  29. to configure it. This comes with the standard ocfs2-tools package.
  30. O2CB is limited to maintaining a cluster for OCFS2 file systems.
  31. It cannot manage any other cluster applications.
  32. It is always safe to say Y here, as the clustering method is
  33. run-time selectable.

  38. help
  39. This option will allow OCFS2 to use userspace clustering services
  40. in conjunction with the DLM in fs/dlm. If you are using a
  41. userspace cluster manager, say Y here.
  42. It is safe to say Y, as the clustering method is run-time
  43. selectable.

  49. This option allows some fs statistics to be captured. Enabling
  50. this option may increase the memory consumption.

  56. The ocfs2 filesystem has an extensive logging system. The system
  57. allows selection of events to log via files in /sys/o2cb/logmask/.
  58. This option will enlarge your kernel, but it allows debugging of
  59. ocfs2 filesystem issues.

  64. help
  65. This option will enable expensive consistency checks. Enable
  66. this option for debugging only as it is likely to decrease
  67. performance of the filesystem.
