hi,

we are having some trouble with our rhel 7 to rhel 8 migration and after checking some things, it became apparent the replication is mostly broken among the idm servers

I see in the errors:

`agmt=%s(%s:%d): Can't locate CSN %s in the changelog (DB rc=%d). The consumer may need to be reinitialized`

According to this:

https://access.redhat.com/documentation/en-us/red_hat_directory_server/11/html/administration_guide/managing_replication-troubleshooting_replication_related_problems

Reason: Most likely the changelog was recreated because of the disk is full or the server ungracefully shutdown.

/var/log on this hosts was full recently, so this could have caused this indeed.

I also see:

ERR - NSMMReplicationPlugin - send_updates - .... : data required to update replica has been purged from the changelog, if the error persists the replica must be reinitialized.

This is pretty clear.

So this server is the ca master.

The domain level is 1.

The rhel version is right now 7.9.

If I reinitialize this server with the ca role (master), with other server, will it overwrite the CA?

Regards,

natxo
