Does an ESEUTIL defrag of an Exchange store also perform an integrity check/repair on it?
- by Bigbio2002
Earlier this morning, store.exe fuzzled up in one way or another, which necessitated a restart of our Exchange server. It came back online with no errors or problems, all the transaction logs replayed successfully, and all the stores mounted as normal. To me, it was just one of those random crashes; however, our consultant suspects it was caused by corruption in one of the stores. Perhaps he's correct, since he has far more experience than me, but that's not the point.
To fix the suspected errors, he's planinng to run an ESEUTIL defrag (via PerfectDisk) to fix them, which he claims will also fix any errors present.
From what I understand, defrag, verify, and repair are 3 separate actions, and a defrag does not imply any kind of integrity check. Is this correct? Are there any dangers of running a straight-up defrag on a database that might be corrupt?
Edit:
Here's the first error in the event log, which indicated the start of the problems we were having. Anyone know what it might indicate?
