[Fedora-directory-users] Multi-Master Replication Problems

[Wendt, Trevor]

> I'm having some significant issues getting my multi-master servers
> synchronized after a network outage this past weekend. First I was
> getting: 
> 
> error--> NSMMReplicationPlugin - agmt="cn=srv1-to-srv2" (srv2:389):
> Replica has a different generation ID than the local data.
> 
> Then after numerous attempts to clear out the change log and
> reinitialize the consumer from srv1 to srv2, and failing each time
> hitting a "ratio 0%" error (we increased server memory and
> corresponding database/cache settings to no avail): 
> 
> error--> import userRoot: Processed 48136 entries -- average rate
> 2292.2/sec, recent rate 2292.1/sec, hit ratio 0%
> 
> Finally tried a local file restore db2ldif (with -r) and ldif2db and
> one from db2bak. Upon restore on both servers, now on the "good"
> server (srv1) I see:
> 
> error--> NSMMReplicationPlugin - replica_check_for_data_reload:
> Warning: data for replica dc=<mydomain>,dc=com was reloaded and it no
> longer matches the data in the changelog (replica data > changelog).
> Recreating the changelog file. This could affect replication with
> replica's consumers in which case the consumers should be
> reinitialized.
> 
> AND 
> 
> error--> NSMMReplicationPlugin - csnplCommit: can't find csn
> 45ee0228000000010000
> error--> NSMMReplicationPlugin - ruv_update_ruv: cannot commit csn
> 45ee0228000000010000
> error--> NSMMReplicationPlugin - replica_update_ruv: unable to update
> RUV for replica dc=<mydomain>,dc=com, csn = 45ee0228000000010000
> 
> These are both after clearing the changelogdb (multiple times) and of
> course no synchronization.
> 
> At this point I am stuck and would appreciate any help in getting this
> resolved. First I need to resolve the "NSMMReplicationPlugin -
> csnplCommit: can't find csn" problems so I can try the command line
> again.
