(ITS#6489) Incomplete Master/Slave Replication
Full_Name: Frank Offermanns
Version: 2.4.21
OS: Windwos
URL: ftp://ftp.openldap.org/incoming/
Submission from: (NULL) (217.6.189.242)
I am running LDAP from Head with BDB 4.8.26 as backend on windows. I am testing
master/slave replication while adding 10000 users with 10 filled attributes.
I am not using a specific time synchronization. Standard windows time
synchronization in domains is active. But as far as I understood, a microsecond
time synchronisation is only needed for master-master, which I am not testing.
My problem is, that not every user and/or every attribute is replicated from my
master to my slave.
If the replicationmode is refreshAndPersist more entries are incorrect on the
slave.
When doing refreshOnly (every 5 mins) fewer entries have this problem.
Switching to delta-syncrepl changes this behaviour.
With delta-syncrepl once the intial content load has run, the replication seems
to work 100%.
But when I add entries while the inital content load (empty slave database) is
running, a few complete users are missing (seems to be always a few in a row).
But every written user has all attributes, so no missing attributes in this
case.
I will post my configuration (for refreshAndPersist replication).
If you need any other info please let me known.
Here my configurations:
