NAME

       cmsync - Synchronize files or directories on multiple Serviceguard nodes.

SYNOPSIS

       cmsync [-rv] [[-n node_name]...]  [src_node:]src_file [...]

DESCRIPTION

       cmsync copies files and/or directories to multiple Serviceguard nodes.

       cmsync  is  limited  in several ways. cmsync is best suited for situations where other remote copy facilities are not available. For a more
       full featured tool for copying files between Serviceguard nodes, see ccp(1m) provided by Distributed Systems Administration Utilities.

       To use this command, the local user must have the root access role on each of the involved nodes.  For  more  information  on  Serviceguard
       access control policies, see the manual, Managing Serviceguard.

       To  use	the  cmsync command without specifying -n options, the local node must be configured into a Serviceguard cluster. If no -n options
       are specified, the files will be copied to all available nodes in the cluster.

       Paths may be relative to the current working directory or specified absolutely.	Copies between two remote hosts are permitted.

       If a file or directory already exists on a destination node, the destination node's copy will be overwritten with no prompting.

       The cmsync command is not suited for large files or large numbers of files and may result in a heavy load on the command  and  Serviceguard
       daemons. Other tools such as ccp should be considered for these purposes.

   Options And Arguments
	      -r   Recursively copy entire directories.

	      -v   Verbose output will be displayed.

	      -n node_name
		   Serviceguard  node to copy file to. If no -n options are specified, default is to copy to all nodes within the configured clus-
		   ter.

	      src_node
		   Serviceguard node to retrieve the file from. Defaults to the local node.

	      src_file
		   Path to source file on src_node.

RETURN VALUE

       cmsync returns the following values:

	       0   Successful completion.
	       1   Command failed.

EXAMPLES

       Copy the local file /etc/hosts to remote nodes node1 and node2

	      cmsync -n node1 -n node2 /etc/hosts

       Distribute the remote file /etc/passwd  to all nodes in the cluster.

	      cmsync node1:/etc/passwd
