Backport #17445

Updated by Nathan Cutler almost 7 years ago

https://github.com/ceph/ceph/pull/16355 In our ceph cluster some rbd images (create by openstack) make rbd segfault. This is on a ubuntu 14.04 with mitaka cloud archive. There are some Xenial (16.04) machines in the cluster with the same Ceph version. On these machines rbd also segfaults.

  NOTE: a copy of the executable, or `objdump -rdS <executable>` is needed to interpret this. 


 Objdump is to large for this bug tracker. I can provide this by email. The full segfault message is attached to this issue.
