Hi,
thanks for the confirmation. In this case, you can fix the issue with the
following procedure:
To fix the master that was missing the "cn=changelog5,cn=config" entry
follow these steps:
[1] Remove the directory /var/lib/dirsrv/slapd-XXX/cldb
[2] Use ldapmodify and add this entry
dn: cn=changelog5,cn=config
changetype: add
objectclass: top
objectclass: extensibleObject
cn: changelog5
nsslapd-changelogdir: /var/lib/dirsrv/slapd-XXX/cldb
nsslapd-changelogmaxage: 30d
[3] Reinitialize this master from another "good" master, as this
master is most likely out of date now.
Don't forget to replace the slapd-XXX with your actual instance name.
HTH,
flo

Hi Florence -
Thank you for your response. So to answer your question -
1) the directory does exist on the master
2) the cn=changelog5,cn=config entry is missing in the dse.ldif file.
Thanks.

Hi,
the error looks similar to
https://bugzilla.redhat.com/show_bug.cgi?id=1590974
Most of the comments are private in this BZ because they refer to customer
deployments, but the issue can happen if cn=changelog5,cn=config is missing
on the master AND the changelog directory is present.
Can you check on the master if there is a directory:
/var/lib/dirsrv/slapd-XXX/cldb and if there is an entry
cn=changelog5,cn=config in /etc/dirsrv/slapd-XXX/dse.ldif?
