This version - covers how ocfs2 uses distributed locking between cluster - nodes. - - The protocol version has a major and minor number. Two - cluster nodes can interoperate if they have an identical - major number and an overlapping minor number - thus, - a node with version 1.10 can interoperate with a node - sporting version 1.8, as long as both use the 1.8 protocol. - - Reading from this file returns a single line, the major - number and minor number joined by a period, eg "1.10". - - This file is read-only. The value is compiled into the - driver. - -What: /sys/fs/ocfs2/loaded_cluster_plugins -Date: April 2008 -Contact: ocfs2-devel@oss.oracle.com -Description: - The /sys/fs/ocfs2/loaded_cluster_plugins file describes - the available plugins to support ocfs2 cluster operation. - A cluster plugin is required to use ocfs2 in a cluster. - There are currently two available plugins: - - * 'o2cb' - The classic o2cb cluster stack that ocfs2 has - used since its inception. - * 'user' - A plugin supporting userspace cluster software - in conjunction with fs/dlm. - - Reading from this file returns the names of all loaded - plugins, one per line. - - This file is read-only. Its contents may change as - plugins are loaded or removed. - -What: /sys/fs/ocfs2/active_cluster_plugin -Date: April 2008 -Contact: ocfs2-devel@oss.oracle.com -Description: - The /sys/fs/ocfs2/active_cluster_plugin displays which - cluster plugin is currently in use by the filesystem. - The active plugin will appear in the loaded_cluster_plugins - file as well. Only one plugin can be used at a time. - - Reading from this file returns the name of the active plugin - on a single line. - - This file is read-only. Which plugin is active depends on - the cluster stack in use. The contents may change - when all filesystems are unmounted and the cluster stack - is changed. - -What: /sys/fs/ocfs2/cluster_stack -Date: April 2008 -Contact: ocfs2-devel@oss.oracle.com -Description: - The /sys/fs/ocfs2/cluster_stack file contains the name - of current ocfs2 cluster stack. This value is set by - userspace tools when bringing the cluster stack online. - - Cluster stack names are 4 characters in length. - - When the 'o2cb' cluster stack is used, the 'o2cb' cluster - plugin is active. All other cluster stacks use the 'user' - cluster plugin. - - Reading from this file returns the name of the current - cluster stack on a single line. - - Writing a new stack name to this file changes the current - cluster stack unless there are mounted ocfs2 filesystems. - If there are mounted filesystems, attempts to change the - stack return an error. - -Users: - ocfs2-tools <ocfs2-tools-devel@oss.oracle.com> |
