Can't Mount Databases in the Recovery Storage Group in Exchange 2003

Question

After restoring some mail stores, mounting them in the recovery storage group errors out. So far a repair with eseutil (which the log says was successful) and a server reboot has been tried. A defrag is currently running on the mail store

I need to go through this again to post the exact error codes, so I will be updating this question. But I thought someone who does this a lot might have a "More times than not..." answer in the meantime.

An Internal Processing Error has occurented. Try restart the exchange ... (Nothing more useful here)

Answer 1

When you restored the EDB, did you restore the log chain and STM (as joeqwerty points out) as well? I'm not 100% positive on how NetBackup does it's backups, but it probably uses VSS, which means that when the backup is taken, the EDB is in an inconsistent state. A VSS backup will flush the cache to disk, but it doesn't roll the logs into the database. When you're setting up the RSG and trying to mount the database, make sure that you have the EDB, STM, and logs from the same backup timestamp. When you mount the database, the logs will be rolled into the EDB, bringing it to a consistent state, and it should mount.

Answer 2

EventID.net suggests that the problem might be a missing streaming file (.stm) for the DB in question.

Answer 3

Use following steps to run Soft and Hard Recovery.

Run Soft Recovery

• First check log files should be in a Clean state:

  Eseutil /ml “Path of the log files\log prefix”

• If the log files are healthy, then perform the Soft recovery:

  Eseutil/r /l “Path of the log files” /d “Path of the database”

  Once the command completes then mount the database

Run HARD RECOVERY:

• If log files are not in clean state or missing, then perform Hard recovery.

  eseutil /p “D:\Exchsrvr\Mailbox Store (SERVER).edb”

• Run OFFLINE DEFRAG: Once hard recovery finishes, you need to defrag the databases, for this, You must have space for hard disk equal to 110% size of the database that you want to defragment.

  eseutil /d “D:\Exchsrvr\Mailbox Store (SERVER).edb”

• Once defragment done, Mount & the Dismount the store immediately then perform below steps:

Run ISINTEG:

isinteg -s (SERVER) -fix -test alltests
