No, the issue is probably dom_md/ids accessed by sanlock, but removing files
accessed by sanlock will not help, an open file will remain open until sanlock
close the file.

Did you try to reboot the host before installing it again? If you did and you
still have these issues, you probably need to remove the previous installation
properly before installing again.

Adding Simone to help with uninstalling and reinstalling hosted engine.
