6 Verify that an IP address can be added to a node using 'ctdb addip'.
8 This test goes to some trouble to figure out which IP address to add
9 but assumes a 24-bit subnet mask. It does not handle IPv6. It does
10 not do any network level checks that the new IP address is reachable
11 but simply trusts 'ctdb ip' that the address has been added. There is
12 also an extra prerequisite that the node being added to already has
13 public addresses - this is difficult to avoid if the extra address is
14 to be sensibly chosen.
18 * An active CTDB cluster with at least 2 active nodes.
22 1. Verify that the status on all of the ctdb nodes is 'OK'.
23 2. Use 'ctdb ip' on one of the nodes to list the IP addresses being
25 3. Add an additional public address to be served by the node, using
27 4. Verify that this IP address has been added to the list of IP
28 addresses being served by the node, using the 'ctdb ip' command.
32 * 'ctdb ip' adds an IP address to the list of public IP addresses
33 being served by a node.
