Hi,
I've seen this in 0.56. In my case I shutdown one server then bring it back. I have to run /etc/init.d/ceph -a restart to make it healthy. It doesn't impact the running VM I have in that cluster though.On Wed, Apr 3, 2013 at 8:32 PM, Martin Mailand <martin@xxxxxxxxxxxx> wrote:
Hi,
I still have this problem in v0.60.
If I stop one OSD, the OSD get set down after 20 seconds. But after 300
seconds the OSD get not set out, there for the ceph stays degraded for ever.
I can reproduce it with a fresh created cluster.
