A few days ago, we did an offline defrag on our exchange database. We have to make it to a new partition.

The command was:

"C:\Program Files\Exchsrvr\bin\eseutil.exe" /d /p /i "E:\Program Files\Exchsrvr\MDBDATA\priv1.edb" /t"G:\tempdfguj.edb"

We thought everything was ok. When the job was done, we copied the new files from G:\ to the original location, mounted the store and we happy... But unfortunately, to this day we can't make online backups because we got the following error message:

Information Store (6552) The streaming page read from the file "E:\Program Files\Exchsrvr\MDBDATA\priv1.STM" at offset 270336 (0x0000000000042000) for 464 (0x000001d0) bytes failed verification due to a page checksum mismatch. The expected checksum was 3052248573 (0x00000000b5ed9dfd) and the actual checksum was 2309737967 (0x0000000089abcdef). The read operation will fail with error -613 (0xfffffd9b). If this condition persists then please restore the database from a previous backup. For more information, click http://www.microsoft.com/contentredirect.asp.

So I try to read, read, and read... Try everything... eseutil /R ; / mh / k ...so everything... Now I decided to make a new defrag, but now I do it to STM file too, and I hope this new database will do the trick.

So my question is about the correct steps:

  1. Dismount store, stop services, etc.
  2. Make an offline backup
  3. Run script
  4. May I delete the transaction logs?
  5. Copy back new files to original place.
  6. Mount, start services...

Try this:

  1. Dismount store.
  2. eseutil /mh - make sure it's in clean.
  3. Move the logs somewhere else, mount the store.

if will not work, perform eseutil /p and then remove all the logs, make sure to leave the DB directory empty except edb and stm files, make sure logs are remove. That should work.

  • Before you answer, i started something else. The defrag is interrupted, so we decided we victimize our STM file. We use MAPI so we have relative small STM file. (and we have backup e-mail server with KERIO, so if something lost, than we can open the mail on this server) – holian Jan 12 '12 at 0:51
  • Very strange, but with this procedure, the EDB file grove up with almost 2 GB. Is this normal? (eseutil /p / createstm priv1.edb) – holian Jan 12 '12 at 0:53
  • What's that "createstm" is for? Don't treat the files as separate. Look at it as one entity. – Vick Vega Jan 12 '12 at 2:41
  • I separeted them 'coz i tougth eseutil only create an stm, and the edb doesn't change. Now the process ready. But now i don't know if i should mount it back or not. Coz' if i mount, and the peding mails arrive and than i should restore the original database...well, im goin crazy...I just want to fix the STM checksum issue... – holian Jan 12 '12 at 3:17
  • I would start with the database in "clean" shutdown mode. So either restore from backup or somehow get the healthy database and follow the procedure I have outlined. It would be faster than trying to repair existing condition. – Vick Vega Jan 12 '12 at 3:20
