I know that this shouldn't happen frequently, but not having access to
uptodate data is certainly unwanted and there should be a way to prevent it.

DRBD is quite prone to demote failures, especially when filesystem can
not be umounted for some reason. Blocked process for example can't be
killed and filesystems accessed by it can't be unmounted. This problem
is causing 90% of fencing for me.
