onnode 1 onnode run commands on ctdb nodes onnode NODE COMMAND ... onnode is a utility to run commands on a specific node of a CTDB cluster, or on all nodes. The NODE option specifies which node to run a command on. You can specify a numeric node number (from 0 to N-1) or the special node 'all'. The COMMAND can be any shell command. The onnode utility uses ssh or rsh to connect to the remote nodes and run the command. If the COMMAND starts with a /, then the command is run via the 'at' service. Otherwise the command is run in the foreground. The following command would show the process ID of ctdb on all nodes onnode all pidof ctdbd The following command would show the last 5 lines of log on each node, preceded by the nodes hostname onnode all "hostname; tail -5 /var/log/log.ctdb" The following command would restart the ctdb service on all nodes. onnode all service ctdb restart ctdbd(1), ctdb(1), Copyright (C) Andrew Tridgell 2007 Copyright (C) Ronnie sahlberg 2007 This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 3 of the License, or (at your option) any later version.
