Hi.
We have a one master and 8 slaves. From time to time replication has
broken and data has stopped to update on slaves. In logs i see next:
There is no dependence with slaves or versions:
- master has 2.4.50
- slaves have different versions: 2.4.50, 2.4.55, 2.4.57.
All of slaves can breake. We use next configuration:
syncrepl rid=000
provider=ldaps://ldap-master.domain.com
type=refreshAndPersist
retry="5 5 300 +"
searchbase="dc=staff,dc=com"
attrs="*,+"
bindmethod=simple
binddn="cn=slapd-slave,ou=services,dc=staff,dc=com"
We can't try newer version, because use Oracle solaris and there are only
2.4.X versions.
Hello,
OpenLDAP 2.4 is a historic release. I would note that 2.4.59 was the final
2.4 release, and numerous replication bugs were fixed throughout the entire
release series
(<https://git.openldap.org/openldap/openldap/-/blob/OPENLDAP_REL_ENG_2_4/CHANGES>).
Generally I would advise using delta-sync replication with the 2.4 series
given the known problems with standard syncrepl in that release series.
There have also been significant changes made to how sync replication works
in the 2.5 release that could not be done in the 2.4 series that make
standard syncrepl viable.
Finally, I would note that there is nothing that prevents one from
compiling OpenLDAP 2.5 (or later) on Solaris.
Regards,
Quanah
