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

  25config OCFS2_FS_O2CB
  26        tristate "O2CB Kernelspace Clustering"

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

  39config OCFS2_FS_USERSPACE_CLUSTER

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

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

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

  69config OCFS2_DEBUG_FS
  70        bool "OCFS2 expensive checks"

  72        default n
  73        help
  74          This option will enable expensive consistency checks. Enable
  75          this option for debugging only as it is likely to decrease
  76          performance of the filesystem.
