My Zenworks 6.5 Inventory service stopped with an odd error a few days ago claiming their was no more space on the volume. In fact the volume was only half full. The volume does have disk compression turned on. Turns out that compression could be a problem so I copied the files to another part of the volume then copied them back. Now I get this message:

Storer: Database not initialized as it is being upgraded ...Will retry after 300 seconds. This has runs continuously and has for a over a week.

Looks like the DB is corrupted in some fashion. Before I generate a new one I wanted to make sure there weren't any other options.
