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 16 You'll want to install the ocfs2-tools package in order to at least 17 get "mount.ocfs2". 18 19 Project web page: http://oss.oracle.com/projects/ocfs2 20 Tools web page: http://oss.oracle.com/projects/ocfs2-tools 21 OCFS2 mailing lists: http://oss.oracle.com/projects/ocfs2/mailman/ 22 23 For more information on OCFS2, see the file 24 <file:Documentation/filesystems/ocfs2.txt>. 25 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. 39 40config OCFS2_FS_USERSPACE_CLUSTER 41 tristate "OCFS2 Userspace Clustering" 42 depends on OCFS2_FS && DLM 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.
