Hello, Have any of you tried to upgrade the Ceph cluster through the following upgrade path. Dumpling -> Firefly -> Hammer * Each version is newest. After upgrading from Dumpling, Firefly to Hammer following this: http://docs.ceph.com/docs/master/install/upgrading-ceph/ I ended up with hitting ""warnings"" reported on: http://tracker.ceph.com/issues/12715 mds.0 [ERR] bad backtrace on dir ino 600 mds.0 [ERR] bad backtrace on dir ino 601 mds.0 [ERR] bad backtrace on dir ino 602 mds.0 [ERR] bad backtrace on dir ino 603 mds.0 [ERR] bad backtrace on dir ino 604 mds.0 [ERR] bad backtrace on dir ino 605 mds.0 [ERR] bad backtrace on dir ino 606 mds.0 [ERR] bad backtrace on dir ino 607 mds.0 [ERR] bad backtrace on dir ino 608 mds.0 [ERR] bad backtrace on dir ino 609 If I've missed anything, point it out to me.
