3.4. Saving a Configuration Change to a File
3.4. Saving a Configuration Change to a File When using the pcs command, you can use the -f option to save a configuration change to a file without affecting the active CIB. If you have previously configured a cluster and there is already an active CIB, you use the following command to save the raw xml file. For example, the following command saves the raw xml from the CIB into a file named testfile . The following command creates a resource in the file testfile but does not add that resource to the currently running cluster configuration. You can push the current content of testfile to the CIB with the following command.
pcs cluster cib filename pcs cluster cib testfile pcs -f testfile resource create VirtualIP ocf:heartbeat:IPaddr2 ip=192.168.0.120 cidr_netmask=24 op monitor interval=30s pcs cluster cib-push testfile
