lost log files of passive DAG copy
Hello All,
We have two exchange servers 2010 SP3 with DAG setup. Each server contains two mailbox database as primary and two as secondary. We got notified that one server is facing a hardware raid problem. So we activated all four databases on the good one to find out the problem of the faulty server. All database are mounted on one server. After troubleshooting the faulty server, we found out the array relating to log files only is lost but database files and operating system are functioning. We have a backup of lost log partition 4 days ago using exchange backup "networker"
Now the status is all clients are connected to one good server contains all databases while other server has copy status "servicedown". I checked the services of replication and found they are down.
I read about replay log files from good server to faulty server and another solution about reseed the database from good one. Which is better solution and what we need to be considered before creating another partition for log files on the faulty server in terms of manual backup, etc.?

Dear Simon,
Thank you for your reply. How about the option of index catalog ? and do I need to backup the DAG mailbox db of the faulty server before reseeding.

This solution is only available to members.
To access this solution, you must be a member of Experts Exchange.
Pretty straight forward process - in most cases Exchange will do all of the work for you.
The backup you have is useless - just reseed. Anything else will confuse Exchange.
