Luis, I have experienced the same problems, what helped was to 'fence' the other node by forcing it into a reboot. I don't quite know why it worked (worrying) but I found that if I fenced the other node, I was not getting any more time-outs on the drbd block device, which I think is what you describe.
I am using HP servers with iLO3 and RHEL/CentOS, so I used the fence_ipmi script included with the CentOS 6.1 distribution (do not forget to attach your fence devices to the correct nodes). Hope it helps! Robert On 13-1-2012 10:59, Luis M.
