Re: Infinite degraded objects

Hello,

I cannot tell what was the previous version since I used the one installed on ubuntu 15.04. Now 16.04.

But what I can tell is that I get errors from ceph osd and mon from time to time. The mon problems are scaring since I have to wipe the monitor and then reinstall a new one. I cannot really understand what's going on. I have never so many problems like after updating.

Should I open a bug report?

like it's been fixed a week or so ago:

Hello,

Since we upgraded ceph cluster we are facing a lot of problems. Most of them
due to osd crashing. What can cause this?
