红帽全球峰会27.14. Removing obsolete RUV records
If you remove a server from the IdM topology without properly removing its replication agreements, obsolete replica update vector (RUV) records will remain on one or more remaining servers in the topology. This can happen, for example, due to automation. These servers will then expect to receive updates from the now removed server. In this case, you need to clean the obsolete RUV records from the remaining servers.
Prerequisites
- You have the IdM administrator credentials.
- You know which replicas are corrupted or have been improperly removed.
Procedure
List the details about RUVs using the
ipa-replica-manage list-ruvcommand. The command displays the replica IDs:$ ipa-replica-manage list-ruv server1.example.com:389: 6 server2.example.com:389: 5 server3.example.com:389: 4 server4.example.com:389: 12重要The
ipa-replica-manage list-ruvcommand lists ALL replicas in the topology, not only the malfunctioning or improperly removed ones.Remove obsolete RUVs associated with a specified replica using the
ipa-replica-manage clean-ruvcommand. Repeat the command for every replica ID with obsolete RUVs. For example, if you knowserver1.example.comandserver2.example.comare the malfunctioning or improperly removed replicas:ipa-replica-manage clean-ruv 6 ipa-replica-manage clean-ruv 5警告Proceed with extreme caution when using
ipa-replica-manage clean-ruv. Running the command against a valid replica ID will corrupt all the data associated with that replica in the replication database.If this happens, re-initialize the replica from another replica using
$ ipa-replica-manage re-initialize --from server1.example.com.
Verification
-
Run
ipa-replica-manage list-ruvagain. If the command no longer displays any corrupt RUVs, the records have been successfully cleaned. If the command still displays corrupt RUVs, clear them manually using this task:
