2.4. 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 a file.

pcs cluster cib filename

pcs cluster cib filename

For example, the following command saves the raw xml from the CIB into a file name testfile.

pcs cluster cib testfile

pcs cluster cib testfile

Copy to Clipboard

Toggle word wrap

The following command creates a resource in the file testfile1 but does not add that resource to the currently running cluster configuration.

pcs -f testfile1 resource create VirtualIP ocf:heartbeat:IPaddr2 ip=192.168.0.120 cidr_netmask=24 op monitor interval=30s

# pcs -f testfile1 resource create VirtualIP ocf:heartbeat:IPaddr2 ip=192.168.0.120 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 filename

pcs cluster cib-push filename
