Problem recover replica

[Manel Gimeno Zaragozá]

Hello agin,



Is there any option to check the integrity of the replica information? I
 mean, some command or script to run and validate that Master and 
Replica have the same information.



Regards.

I've been trying sync_client -r -f log-PID and it works. All the missing changes are applied 
without problem, I should do some script that controls this files and apply them.
anyway the log-PID is not deleted when its processed. I guess we should control the processed log-PIDs manually and move or delete them, am i right?

"sync_client -r" and "sync_server" are initiated. In my test machines I 
should run manually them each time I start cyrus-imapd, I though that it
 could be automatic one I start the service cyrus-imapd, but it is not.
