Hi,
We have exchange 2010 SP3 , 4 mailbox servers in DAG. From last 2-3 days for some of the databases the protection status is showing as synchronizing for more than 30 hours. I tried to cancel running job for one of the databases and manually ran express full backup again. But again its getting stuck on synchronizing state. After few hours data transfer also remains constant. As a result of this logs are not getting truncating and have to increase log drive size constantly.
Request some one to please help to troubleshoot this.
