but the mailboxes in the server manager would not mount.. The error said DB was corrupted. I ran the eseutil /r and a bunch of other /minor/ stuff, all of them failed.. saying http://forums.msexchange.org/How_to_fix_%26quot%3Bbad_checksums%26quot%3B_after_I_ran_Eseutil%25exe_%2Fk/m_150575500/tm.htm there were erorros, checksum problems and more. I tried to restore my DB from a symantec backup, that didn't work. Great.. said the backup was 0 size, and just say there.. wouldn't restore. (Using backup exec 2012) So I did what I didn't want to do... ran the eseutil.exe /p to do a full repair. It is running now... it just hit the second phase of https://community.spiceworks.com/topic/302087-corrupt-exchange-db-help 'rebuilding the MYsysObjects and I am curious as to if I am doing this right, and how long it would take?

Lost Exchange DB store   22 Replies Mace OP Jay6111 Feb 12, 2013 at 2:58 UTC As for time it will take, that depends on the size of the DB and the speed of the disk. In my experience, anything over 20gig and on 7200 disks will more than likely crap out and fail before it finishes and will take up to 8 hours or more. Moving the DB to faster disk and running the utility has worked for me if that happens. There is a chance as always when using the higher level switches in eseutil of data loss.

How did this mount issue occur, i.e. did it just dismount on its own, was there a hardware issue, power failureor ?? 2. How large is the EDB in question. 3. How many logs do you have in terms of #'s and total size of all logs in the folder. 4. How large are the respective drives where the EDB and LOGS are located and how much dis
Exchange TeamMay 1, 20159 0 0 0 The database repair process is often used as a last ditch effort to recover an Exchange database when no other means of recovery is available. The process should only be followed at the advice of Microsoft Support and after determining that all other recovery options have been exhausted. For many years in many versions of Exchange, the repair process has largely been the same. However, that process is changing, based on information Microsoft has gathered from an extensive analysis of support cases. In short, Microsoft is changing the support policy for databases that have had a repair operation performed on them. Originally a database was supported if the repair was performed using ESEUTIL and ISINTEG/repair cmdlets. Under the new support policy, any database where the repair count is greater than 0 will need to be evacuated – all mailboxes on such a database will need to be moved to a new database. Existing Repair Process The process consists of three steps: Repair the database at the page level Defragmentation of the database to restructure and recreate the database Repair of the logical structures within the database Step 1 of the repair process is accomplished by using ESEUTIL /p. This is typically performed when there is page level corruption in the database - for example, a -1018 JET error, or when a database is left in dirty shutdown state as the result of not having the necessary log files to bring the database to a clean shutdown state. After executing ESEUTIL /p you are prompted to confirm that data loss may result. Selecting OK is required to continue.
