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". 17 18 Project web page: http://oss.oracle.com/projects/ocfs2 19 Tools web page: http://oss.oracle.com/projects/ocfs2-tools 20 OCFS2 mailing lists: http://oss.oracle.com/projects/ocfs2/mailman/ 21 22 For more information on OCFS2, see the file 23 <file:Documentation/filesystems/ocfs2.txt>. 24 25config OCFS2_FS_O2CB 26 tristate "O2CB Kernelspace Clustering" 27 depends on OCFS2_FS 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. 38 39config OCFS2_FS_USERSPACE_CLUSTER 40 tristate "OCFS2 Userspace Clustering" 41 depends on OCFS2_FS && DLM 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.
