Hi,
I also have a similar problem, after a bad failover in a EV cluster some indexes started to give me errors in the event log:
Event Type: Error
Event Source: Enterprise Vault
Event Category: Index Server
Event ID: 7292
Date: 17.11.2009
Time: 5:29:53
User: N/A
Computer: Machinename
Description:
The index volume has been marked as failed.
Index Volume: 15A3407290727264C8A139148C5DF188F1110000Machinename/Volume:72 (archivename)
Index Volume Path: E:\Indexing\Index01\15A3407290727264C8A139148C5DF188F1110000machinename
Reference: Makestable
Due to errors accessing the index volume it has been marked as 'failed' to prevent further errors. The index volume will remain inaccessible until it has been repaired.

There are no checksum.dat in those folders and when i tried to update index via admin console, it started to rebuild automaticly
EV version is 2007-SP3
Thanks in advance
