Hi Christoph,

bad news. So to summarize, you have a procedure to cleanup your env, but once you restart the master the ghosts are back.


I really want to find out where they are coming from, so If you have to restart your server, could you please lookup these data, after the server is stopped:

dbscan -f /var/lib/dirsrv/slapd-<INSTANCE>s/db/userRoot/nsuniqueid.db -k =ffffffff-ffffffff-ffffffff-ffffffff -r
=ffffffff-ffffffff-ffffffff-ffffffff
    3
this gives you the RUVID and you can look it up in the database
[root@elkris scripts]# dbscan -f /var/lib/dirsrv/slapd-<INSTANCE>/db/userRoot/id2entry.db -K <RUVID>
id 3
    rdn: nsuniqueid=ffffffff-ffffffff-ffffffff-ffffffff
    nsUniqueId: ffffffff-ffffffff-ffffffff-ffffffff
    objectClass: top
    objectClass: nsTombstone
    objectClass: extensibleobject
    nsds50ruv: {replicageneration} 51dc3bac000000640000
nsds50ruv: {replica 100 ldap://localhost:30522} 557fd541000000640000 557fd9d30
     00000640000
nsds50ruv: {replica 200 ldap://localhost:4945} 557fd6e6000000c80000 557fda0e00
......

then check the contents of the changelog:
[root@elkris scripts]# dbscan -f /var/lib/dirsrv/slapd-<INSTANCE>/changelogdb/ec450682-7c0a11e2-aa0e8005-8430f734_51dc3bac000000640000.db | more

the first entries contain th ruv data:
dbid: 0000006f000000000000
    entry count: 307

dbid: 000000de000000000000
    purge ruv:
        {replicageneration} 51dc3bac000000640000
        {replica 100 ldap://localhost:30522}
        {replica 200 ldap://localhost:30522}

dbid: 0000014d000000000000
    max ruv:
        {replicageneration} 51dc3bac000000640000
        {replica 100} 557fd541000000640000 557fd9d3000000640000
        {replica 200} 557fd6e6000000c80000 557fda0e000000c80000

I've been too early pleased :/ After ipactl restart of our first master (where we re-initialize from) are the 'ghost' rids again there...

I think there is something like a fs backup for dirsrv (changelog?) but where?
