Exchange 2010 Stretched DAG Copy Fails
Posted on 2013-06-06
We've got Exchange 2010 SP3 in a 2 node active/active DAG stretched across 2 locations (350 miles apart, connected by 100 meg link) and every time I add a database copy, on any of our 20 databases, it fails with either "a log file missing on the active copy" or a "source-side 0xfffffae7" error.
If I run Update-MailboxDatabaseCopy -DeleteExistingFiles it will work, but only directly after a backup has run...if I try to seed a copy the next day, it fails.
Any clues as to why my window of opportunity is right after a backup?
