hammer: QEMU VM hangs talking to RBD via librbd
#6 Updated by Stefan Priebe over 4 years ago
i recompiled hammer from current hammer-backport branch which includes #15033. I just replaced librbd and kept the original 0.94.6 versions of ceph-osd running.
While doing sync inside the guest and doing afterwards a snapshot the vm still started to hang completely doing no I/O anymore.
- Is the hammer-backport incomplete?
- do i also need newer ceph-osd processes?
