ESM "Database is unavailable at this time" after upgrade to 11.2.1
After testing an upgrade from 10.3.4 to 11.2.1, the web interface is never available giving a "Database is unavailable at this time" error. After installing the 11.2.1 upgrade and reboot, the drivesetup script runs and fails. The error is "/ has unexpectedly changed". It appears the script detects the new drive space is twice that of the old drive space, exiting the script and not starting any of the additional services including cpservice.
I edited the script and commented out that fail condition and rebooted. The web interface now comes up and everything appears to be working correctly.
I haven't been able to determine why the drivesetup script is detecting a change in the drive space. I did not change any settings on the VM prior to or after the upgrade. Is this a known problem and is there a more official procedure to prevent or address this error?
