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.
pcs cluster cib filename
For example, the following command saves the raw xml from the CIB into a file named testfile.
# pcs cluster cib testfile
The following command creates a resource in the file testfile but does not add that resource to the currently running cluster configuration.
# pcs -f testfile resource create VirtualIP ocf:heartbeat:IPaddr2 ip= cidr_netmask=24 op monitor interval=30s
You can push the current content of testfile to the CIB with the following command.
# pcs cluster cib-push testfile
