It supports 64 bit inode 15 numbers, and has automatically extending metadata groups which may 16 also make it attractive for non-clustered use. 17 18 You'll want to install the ocfs2-tools package in order to at least 19 get "mount.ocfs2". 20 21 Project web page: https://ocfs2.wiki.kernel.org/ 22 Tools web page: https://github.com/markfasheh/ocfs2-tools 23 OCFS2 mailing lists: https://subspace.kernel.org/lists.linux.dev.html 24 25 For more information on OCFS2, see the file 26 <file:Documentation/filesystems/ocfs2.rst>. 27 28config OCFS2_FS_O2CB 29 tristate "O2CB Kernelspace Clustering" 30 depends on OCFS2_FS 31 default y 32 help 33 OCFS2 includes a simple kernelspace clustering package, the OCFS2 34 Cluster Base. It only requires a very small userspace component 35 to configure it. This comes with the standard ocfs2-tools package. 36 O2CB is limited to maintaining a cluster for OCFS2 file systems. 37 It cannot manage any other cluster applications. 38 39 It is always safe to say Y here, as the clustering method is 40 run-time selectable. 41 42config OCFS2_FS_USERSPACE_CLUSTER 43 tristate "OCFS2 Userspace Clustering" 44 depends on OCFS2_FS && DLM 45 default y 46 help 47 This option will allow OCFS2 to use userspace clustering services 48 in conjunction with the DLM in fs/dlm.
