Users on LOUIE DB3_1 are currently unable to access their mailboxes due to a hardware level issue with the storage device. The database was a temporary database used as a temporary holding spot for mailboxes that were moving from DB3 which was being phased out on LOUIE. Unfortunately since this was a temporary database there was no anticipated need to make multiple database copies available as the extra over head could cause production performance issues. To rectify the issue we’ve been running a hardware RAID level resync to ensure all data is in the best state possible. We do anticipate the issue being resolved before the start of business on Monday.
As a reminder, partners are able to use LiveArchive (https://livearchive.exchangedefender.com) to access their live running mail during the outage
Update 9:07 AM: We are currently running an eseutil integrity check on the log files for DB3_1. This check will ensure that all the data that is present on the database is correct and true, as well as any uncommitted data can be finally committed. This process is expected to take up to two hours to complete. If the replay and check complete without error we will then be able to safely mount the database. All mail that hasn’t been delivered is still queued and waiting for delivery.
Update 5:30 PM: The database was successfully mounted after the integrity check completed. In order to prevent this from reoccurring we are adding a database copy to this database. Please keep in mind that this database was a transitional database, used temporarily to move users from DB3 which was in the process of being phased out. We’re extremely sorry for the inconvenience this has caused and we will include transitional databases in DAG setups going forward.
