All, We've just discovered an issue that impacts some users running any of the "ceph osd pool set" family of commands while some of their monitors are running Dumpling and some are running Emperor. Doing so can result in the commands being interpreted incorrectly and your cluster being accidentally misconfigured (eg, accidentally setting extremely large pg_num values). The solution is simple: don't run "ceph osd pool set" commands while your monitors are running different versions. We will have a point release out in the next few days to resolve this issue. For more information, you can refer to http://tracker.ceph.com/issues/6796. Relatedly, I'm proud to announce this issue was discovered by our automated upgrade testing and we have not seen reports of it from any users. Thank you to our dedicated Q/A developers and testers! :) -Greg Software Engineer #42 @ http://inktank.com | http://ceph.com _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
