It supports 64 bit inode 14 numbers, and has automatically extending metadata groups which may 15 also make it attractive for non-clustered use. 16 17 You'll want to install the ocfs2-tools package in order to at least 18 get "mount.ocfs2". 19 20 Project web page: https://ocfs2.wiki.kernel.org/ 21 Tools web page: https://github.com/markfasheh/ocfs2-tools 22 OCFS2 mailing lists: https://subspace.kernel.org/lists.linux.dev.html 23 24 For more information on OCFS2, see the file 25 <file:Documentation/filesystems/ocfs2.rst>. 26 27config OCFS2_FS_O2CB 28 tristate "O2CB Kernelspace Clustering" 29 depends on OCFS2_FS 30 default y 31 help 32 OCFS2 includes a simple kernelspace clustering package, the OCFS2 33 Cluster Base. It only requires a very small userspace component 34 to configure it. This comes with the standard ocfs2-tools package. 35 O2CB is limited to maintaining a cluster for OCFS2 file systems. 36 It cannot manage any other cluster applications. 37 38 It is always safe to say Y here, as the clustering method is 39 run-time selectable. 40 41config OCFS2_FS_USERSPACE_CLUSTER 42 tristate "OCFS2 Userspace Clustering" 43 depends on OCFS2_FS && DLM 44 default y 45 help 46 This option will allow OCFS2 to use userspace clustering services 47 in conjunction with the DLM in fs/dlm.

Enable 77 this option for debugging only as it is likely to decrease 78 performance of the filesystem. 79
