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 28 config 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 42 config 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. If you are using a 49 userspace cluster manager, say Y here. 50 51 It is safe to say Y, as the clustering method is run-time 52 selectable. 53 54 config OCFS2_FS_STATS 55 bool "OCFS2 statistics" 56 depends on OCFS2_FS && DEBUG_FS 57 default y 58 help 59 This option allows some fs statistics to be captured. Enabling 60 this option may increase the memory consumption. 61 62 config OCFS2_DEBUG_MASKLOG 63 bool "OCFS2 logging support" 64 depends on OCFS2_FS 65 default y 66 help 67 The ocfs2 filesystem has an extensive logging system. The system 68 allows selection of events to log via files in /sys/o2cb/logmask/. 69 This option will enlarge your kernel, but it allows debugging of 70 ocfs2 filesystem issues. 71 72 config OCFS2_DEBUG_FS 73 bool "OCFS2 expensive checks" 74 depends on OCFS2_FS 75 default n 76 help 77 This option will enable expensive consistency checks. Enable 78 this option for debugging only as it is likely to decrease 79 performance of the filesystem.
