I've been experiencing problems with a exchange database after removing and readding it to a passive node. After a total reseed which also deleted the old files i ran into an error telling me that one of the transaction logs wasn't present any more.
After a lot of googling and reading on technet I found the answer to be in doing the Update-MailboxDatabaseCopy -CatalogOnly command on the failed database. However, the DB have now been stuck in "Reinitializing" for a good two hours. I understand that this is probably quite normal on a 100-300Gb database with ~8Gb of CatalogData.
So, I still can't help to wonder - is it normal for the resynchronization to take this long. If yes - what is a reasonable time estimate for the resynchronization?
