It appears you have discovered a bug in librbd that occurs when a child's parent image is missing or corrupt. I have opened the following ticket for this issue: http://tracker.ceph.com/issues/10030.
For the OSD failure, can you start a new email thread with the supporting details of that issue?

Subject: RBD command crash & can't delete volume!
# rbd -p volumes info volume-e110b0a5-5116-46f2-99c7-84bb546f15c2
# rbd -p volumes rm volume-e110b0a5-5116-46f2-99c7-84bb546f15c2
PS: This problem makes me unable to start an osd too. (If i star this osd, it die few minutes after that. I retried many times but got the same result.)
Thank you!
