[Re-adding the list.] When the OSDs crash they will print out to their log a short description of what happened, with a bunch of function names. Unfortunately the problem you've run into is probably non-trivial to solve as you've introduced a bit of a weird situation into the permanent record that your OSDs need to process. I've created a bug (http://tracker.ceph.com/issues/4699), you can follow that. :) -Greg Software Engineer #42 @ http://inktank.com | http://ceph.com On Wednesday, April 10, 2013 at 8:57 AM, Witalij Poljatchek wrote: > there are no data. > > Plain OSDs > > > What you mean backtrace ? strace of ceph-osd process ? > > > is easy to reproduce. > > setup plain cluster > > and then set: > > ceph osd pool set rbd size 0 > > after minute set: > > ceph osd pool set rbd size 2 > > that all. > > > > > > > On 04/10/2013 05:24 PM, Gregory Farnum wrote: > > Sounds like they aren't handling the transition very well when trying to calculate old OSDs which might have held the PG.
