Gasp, I suspect the problem seems to be here. In the agreements I see dn: cn=it 2--\3E1,cn=replica,cn=c\3Dit,cn=mapping tree,cn=config objectClass: top objectClass: nsds5replicationagreement cn: it 2-->1 cn: it 2--\>1 nsDS5ReplicaRoot: c=it description: it 2-->1 nsDS5ReplicaHost: srv1.example.com nsDS5ReplicaPort: 389 nsDS5ReplicaBindMethod: simple nsDS5ReplicaTransportInfo: LDAP nsDS5ReplicaBindDN: cn=replication manager,cn=config nsds50ruv: {replicageneration} 60704f730000c3500000 nsds50ruv: {replica 50001 ldap://srv1.example.com:389} 607424dd0000c3510 000 60ba18fb0000c3510000 nsds50ruv: {replica 50000 ldap://srv.example.com:389} 6074264a0000c3500000 6 0ba190f0000c3500000 nsds50ruv: {replica 50002 ldap://srv2.example.com:389} 607426410000c3520 000 60ba19050000c3520000 nsruvReplicaLastModified: {replica 50001 ldap://srv1.example.com:389} 00 000000 nsruvReplicaLastModified: {replica 50000 ldap://srv.example.com:389} 0000000 0 nsruvReplicaLastModified: {replica 50002 ldap://srv2.example.com:389} 00 000000 nsds5replicareapactive: 0 nsds5replicaLastUpdateStart: 20210604124542Z nsds5replicaLastUpdateEnd: 20210604124542Z nsds5replicaChangesSentSinceStartup:: NTAwMDI6NC8wIA== The replica ID 50000 corresponds to the server srv3.example.com, the first host installed in a set of three multimaster servers. The balancer host is srv.example.com. As suggested by dscreate I put the balancer host in the parameter "full_machine_name" for all LDAP servers. For a reason which I don't know the full_machine_name (the load balancer host) has been written in the ruv in place of the fqdn of the machine host containing the dirsrv installation. In this case, srv.example.com in place of srv3.example.com. I suspect that if I reinstall all servers with their hostname in "full_machine_name" I resolve my issue. Any idea?
