hi, I recently upgraded a centos 6.8 realm to centos 7.2 and it almost went correctly.
Now I see some errors in /var/log/dirsrv/slapd-INSTANCENAME/errors 26/Sep/2016:13:20:15 +0200] attrlist_replace - attr_replace (nsslapd-referral, ldap://kdc03.unix.iriszorg.nl:389/o%3Dipaca) failed and according to http://www.freeipa.org/page/Troubleshooting#Replication_issues this points to a ruv problem. So let's enumerate. We had kdc01 replicating to kdc02 (both 6.8). Then I created a replica from kdc01 to kdc03 (running 7.2). And from kdc03 to kdc04 (both 7.2). kdc01 and kdc02 are decommissioned, but kdc02 still shows in both kdc03 and kdc04: $ ipa-replica-manage list kdc02.unix.iriszorg.nl: master kdc03.unix.iriszorg.nl: master kdc04.unix.iriszorg.nl: master and in $ ipa-csreplica-manage list Directory Manager password: kdc02.unix.iriszorg.nl: master kdc03.unix.iriszorg.nl: master kdc04.unix.iriszorg.nl: master >From kdc03: $ ldapsearch -Z -h kdc04.unix.iriszorg.nl -D "cn=Directory Manager" -W -b "o=ipaca" "(&(objectclass=nstombstone)(nsUniqueId=ffffffff-ffffffff-ffffffff-ffffffff))" | grep "nsds50ruv\|nsDS5ReplicaId" Enter LDAP Password: nsDS5ReplicaId: 1095 nsds50ruv: {replicageneration} 50c1015c000000600000 nsds50ruv: {replica 1095 ldap://kdc04.unix.iriszorg.nl:389} 57e4d75a0000044700 nsds50ruv: {replica 66 ldap://kdc03.unix.iriszorg.nl:389} 57e23f66000000420000 nsds50ruv: {replica 96 ldap://kdc01.unix.iriszorg.nl:7389} 50c1016c00000060000 nsds50ruv: {replica 71 ldap://kdc03.unix.iriszorg.nl:389} 57e140c7000000470000 nsds50ruv: {replica 97 ldap://kdc02.unix.iriszorg.nl:7389} 50c1016800000061000 and from kdc04: # ldapsearch -Z -h kdc04.unix.iriszorg.nl -D "cn=Directory Manager" -W -b "o=ipaca" "(&(objectclass=nstombstone)(nsUniqueId=ffffffff-ffffffff-ffffffff-ffffffff))" | grep "nsds50ruv\|nsDS5ReplicaId" Enter LDAP Password: nsDS5ReplicaId: 1095 nsds50ruv: {replicageneration} 50c1015c000000600000 nsds50ruv: {replica 1095 ldap://kdc04.unix.iriszorg.nl:389} 57e4d75a0000044700 nsds50ruv: {replica 66 ldap://kdc03.unix.iriszorg.nl:389} 57e23f66000000420000 nsds50ruv: {replica 96 ldap://kdc01.unix.iriszorg.nl:7389} 50c1016c00000060000 nsds50ruv: {replica 71 ldap://kdc03.unix.iriszorg.nl:389} 57e140c7000000470000 nsds50ruv: {replica 97 ldap://kdc02.unix.iriszorg.nl:7389} 50c1016800000061000 So now I have to run a clen ruv task like this (as seen in https://www.redhat.com/archives/freeipa-users/2016-May/msg00043.html): # ldapmodify -ZZ -D "cn=directory manager" -W -a dn: cn=clean 13, cn=cleanallruv, cn=tasks, cn=config objectclass: extensibleObject replica-base-dn: o=ipaca replica-id: 13 cn: clean 13 And in my example, the replica id would be 66, 96, 71 and 97, correct? Thanks for confirming this, never done it before. -- Groeten, natxo
