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
...

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.

:
- 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" ----------------------------------------------------------
- On
