6 ccs - Cluster Configuration System
7
9 ccs [-h hostname | -f filename] [options]
10
12 ccs allows an administrator to create, modify and view a cluster con‐
13 figuration file on a remote node through ricci or on a local file sys‐
14 tem. Using ccs an administrator can also start and stop the cluster
15 services on one or all of the nodes in a configured cluster.
16
18 Generally all command lines must specify either a hostname or filename
19 to act upon.
20 MAIN OPTIONS
22 --help Display this help and exit
23 -h, --host host
25 Cluster node to perform actions on
26 -f, --file file

29 -p, --password
31 Ricci user password for node running ricci
32 --getconf
34 Print current cluster.conf file
35 --setconf
37 Use the file specified by '-f' to send to the host specified
38 with '-h'
39 --checkconf
41 If file is specified, verify that all the nodes in the file have
42 the same cluster.conf as the file. If a host is specified then
43 verify that all nodes in the host's cluster.conf file have the
44 identical
45 --sync Sync config file to all nodes
47 --activate
49 Activate config on node (use this option with --sync to activate
50 config on all nodes)
51 --debug
53 Display debugging information to help troubleshoot connection
54 issues with ricci
