This doesn't get the ctdb code fully working in Samba4, it just gets it building and not breaking non-clustered use of Samba. It will take a bit longer to update some of the calling ctdb_cluster.c code to make it work correctly in Samba4. Note also that Samba4 now only links to the client portion of ctdb. For the moment I am leaving the ctdbd as a separate daemon, which you install separately from http://ctdb.samba.org/.

.SH "DESCRIPTION"
|
|
.PP
|
|
onnode is a utility to run commands on a specific node of a CTDB cluster, or on all nodes.
|
|
.PP
|
|
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'.
|
|
.PP
|
|
The COMMAND can be any shell command. The onnode utility uses ssh or rsh to connect to the remote nodes and run the command.
|
|
.PP
|
|
If the COMMAND starts with a /, then the command is run via the 'at' service. Otherwise the command is run in the foreground.
