[sheepdog-users] Cluster didn't blacklist faulty node

just had a strange problem with one of my nodes. I was still able to
ping the system and it looks like zookeeper still got updates, so the
node wasn't removed out of the cluster, but other sheepdogs were unable
to connect to the system - even SSH was unreachable.

Sheepdog was really slow - "dog vdi list" didn't complete within
minutes. I had to hard-reset the faulty node to get performance back.

Is there anything I can do to handle such problems a bit smarter?

Thanks a lot,
