In some situations, you might have a problem with the vSphere Auto Deploy database. The most efficient recovery option is to replace the existing database file with the most recent backup.
This problem happens only with hosts that are provisioned with vSphere Auto Deploy.
- Stop the vSphere Auto Deploy server service.
- Find the vSphere Auto Deploy log by going to the vSphere Auto Deploy page in the vSphere Client.
- Check the logs for the following message:
DatabaseError: database disk image is malformed.
If you see the message, replace the existing database with the most recent backup.
- Go to the vSphere Auto Deploy data directory at /var/lib/rbd.
The directory contains a file named db, and backup files named db- yyy- mm- dd.
- Rename the current db file.
VMware Support might ask for that file if you call for assistance.
- Rename the most recent backup to db.
- Restart the vSphere Auto Deploy server service.
- If the message still appears in the log, repeat the steps to use the next recent backup until vSphere Auto Deploy works without database errors.
