the ds "Primary/Primary" is in question.

It seems that DRBD  cannot work when both nodes is primary.

This doc may help you get some hint.

Also,inproper configuration might lead to this issue.

IIRC,I also got seg-fault problem for some unclear reason,which may be caused by setting up problem.

You mean ls -l /opt/local go bad, but ls -l /opt/local/* can work well?

what do you mean by work normal? ;-)
other cmd can work, except ls -l /opt/local, though seg-fault already happened?

don't worry about this.
when the previous problem done, this would go away.
