Okay, so it's a feature, neat.  I didn't realize that drbd would handle it
that way; it's a little confusing to see your Syntarget being promoted to

Any ideas about this?  I see other complaints about this on the list.  My
volumes are large-ish, each about 3TB and when they are syncing things get
slow enough for the timeouts to be hit.
