6.4. Removing a Server from the Topology

IdM does not allow removing a server from the topology if one of the following applies:
  • the server being removed is the only server connecting other servers with the rest of the topology; this would cause the other servers to become isolated, which is not allowed
  • the server being removed is your last CA or DNS server
In these situations, the attempt fails with an error. For example, on the command line: 
$ ipa server-del
Server name: server1.example.com
Removing server1.example.com from replication topology, please wait...
ipa: ERROR: Server removal aborted:

Removal of 'server1.example.com' leads to disconnected topology in suffix 'domain':
Topology does not allow server server2.example.com to replicate with servers:
  server3.example.com
  server4.example.com
...

6.4.2. Command Line: Removing a Server from the Topology

Important

Removing a server is an irreversible action. If you remove a server, the only way to introduce it back into the topology is to install a new replica on the machine.
To remove server1.example.com:
  1. On another server, run the ipa server-del command to remove server1.example.com. The command removes all topology segments pointing to the server: 
    [user@server2 ~]$ ipa server-del
Server name: server1.example.com
Removing server1.example.com from replication topology, please wait...
----------------------------------------------------------
Deleted IPA server "server1.example.com"
----------------------------------------------------------
  2. On server1.example.com, run the ipa server-install --uninstall command to uninstall the server components from the machine. 
    [root@server1 ~]# ipa server-install --uninstall
