Hi,

I cannot reproduce the issue.

I do:

Node1 # sheep /home/sheep1 -p 7000
Node2 # sheep /home/sheep1 -p 7000
Node2 # sheep /home/sheep2 -p 7001

Node1 # collie cluster format -c 2
Node1 # collie vdi create test 1G

... in a Linux Guest test, I run the command 'dd if=/dev/vda
of=/dev/zero' in a loop...

Then killed sheep2 on node2, nothing panic or error happened, guest was
still responsive.

Thanks,
Yuan
