Suddenly all of my VM on one host paused with the following error :- 

vm has paused due to unknown storage error

I am using glusterfs storage with distributed replicate replica=2....my storage and compute both running on the same node...

engine logs :- http://ur1.ca/j31iu

Host logs :- http://ur1.ca/j31kk    (I grep it for one Failed VM)

Thanks,
