Hi,
I hit the following Bug. My Setup is very simple I have two osd (osd1
and osd2) and one monitor.
On the fourth machine I mount ceph via the rbd device and I use the rbd
device for a qemu instance.
When I reboot one of the two osds I hit reproducible this bug.
On all machine I use the kernel version 3.1.0-rc5 and ceph version
0.34-1natty from the newdream repro.
Regards,
martin
