I am investigating the cause of the 2153 error right now to see if that will also fix the log truncation issue. I have seen outdated backup software wreak havoc on Exchange 2010 because it isn't compatible thus breaking the replication every time it tried to backup the databases.

It's not until all those errors add up that we see an issue and by that time it's usually to late for a quick fix. The tool is from Microsoft and it is specifically addressing similar performance issues, tool name is SQLIO script and its free. What's more, here is a thread for your reference.

Outlook Web Access If the user was using OWA, they may be prompted with this error during failover but OWA then recovers without needing to log out and back in: DAG Databases are switchingto single server in DAG.

If the log file is lost, the database copy will need to be reseeded using Update-MailboxDatabaseCopy. Continuous Replication - Block Mode Encountered An Unexpected Communication Error Ok, now we have confirmed that our DAG is in a healthy state before we go ahead and test it (break it?), we can begin with our first test. Also check if there are any latest patches updated on all the copies (both windows and Exchange) Also check if there are any third party softwares(antispam,antivirus) performing any scan during that visit This could indicate a failing or corrupt DB, in which case you would need to determine which one (the last command above should help with this) then make a new DB,
Our backup schedule of exchange daily is 21:30PM ,For the antivirus ,this problem is happening if antivirusis installed or after uninstalling the node32 antivirus . Update-mailboxdatabasecopy Outlook 2016 Outlook in online mode may become unresponsive and you may see the warning below. Log truncation will occur automatically on the passive copies after that log file is copied.

Or Creating a few new and moving mailboxes. Get-mailboxdatabasecopystatus But over 50 I would recommend multiple DB's. Also check for any DC/GC connectivity errors in the active node application logs Please mark as helpful if you find my contribution useful or as an answer if it does answer
Next time I'll run that on the 2nd Exchange server before rebooting that in order to move things back over to the primary. You just got me back up and running again!ReplyDeleteAnonymousJuly 14, 2014 at 8:04 AMThis is impressive and also great information. The passive database copy has been suspended. Doesn't really give me much to go on... is it a Virtual machine?

The only thing that I disabled was unchecking the option for the consistency check in the scheduled job as the datastores are so large that the backup takes about 16 hrs This can be beneficial to other community members reading the thread. The communication error was: An error occurred while communicating with server 'server2'. I am going through this issue now and enabled circular logging to clear the logs and am going to run the DB backup tonight.
SQLIOcan simulate the issue becuase itsend to the stroage high R/W which cuased in our case exchange DB auto failover .
