Comment 11 for bug 1459781

from request of Eugene Bogdanov
Clear steps to reproduce and expected result vs actual result
Run Rally scenario create_and_attach_volume rally scenario

Rough estimate of the probability of user facing the issue
Low. It happens in Rally but could not be reproduced in the mod-linux lab. The issue is that if it fails once in Rally, there is no retry logic at the Cinder level.

What is the real user facing impact / severity and is there a workaround available?

IMPACT: Connection to Ceph hangs and users can not attach volumes to VMs.
WORKAROUND: Restart Cinder services

Can we deliver the fix later and apply it easy on running env?
yes, add retry logic
