  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.

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

  26config OCFS2_FS_O2CB
  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.

  40config OCFS2_FS_USERSPACE_CLUSTER
  41        tristate "OCFS2 Userspace Clustering"

  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
  50          selectable.

  52config OCFS2_FS_STATS

  56        help
  57          This option allows some fs statistics to be captured. Enabling
  58          this option may increase the memory consumption.

  64        help
  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.

  70config OCFS2_DEBUG_FS
  71        bool "OCFS2 expensive checks"

  73        default n
  74        help
  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.
