After a lot of messing about I have manually created a monmap and got the two new monitors working for a total of three. But to do that I had to delete the first monitor which for some reason was coming up with a bogus fsid after manipulated the monmap which I checked and it had the correct fsid. So I recreated it with the right fsid and after that I had three monitors with quorum. I had to manually put the keys in place on the recreated monitor too. But now all of my OSDs have disapeared! Apparently the mon I deleted was storing some special knowledge of the OSDs? The mon log says: 2016-11-03 18:31:26.612012 7f7139529700 0 mon.ceph01@0(leader).data_health(14) update_stats avail 96% total 51175 MB, used 1744 MB, avail 49430 MB 2016-11-03 18:31:26.679911 7f7138d28700 0 cephx server osd.3: couldn't find entity name: osd.3 2016-11-03 18:31:26.876589 7f7138d28700 0 cephx server osd.6: couldn't find entity name: osd.6 2016-11-03 18:31:26.996219 7f7138d28700 0 cephx server osd.14: couldn't find entity name: osd.14 2016-11-03 18:31:27.016283 7f7138d28700 0 cephx server osd.41: couldn't find entity name: osd.41 2016-11-03 18:31:27.016406 7f7138d28700 0 cephx server osd.37: couldn't find entity name: osd.37 2016-11-03 18:31:27.016606 7f7138d28700 0 cephx server osd.40: couldn't find entity name: osd.40 2016-11-03 18:31:27.017276 7f7138d28700 0 cephx server osd.48: couldn't find entity name: osd.48 2016-11-03 18:31:27.291934 7f7138d28700 0 cephx server osd.4: couldn't find entity name: osd.4 2016-11-03 18:31:27.292598 7f7138d28700 0 cephx server osd.5: couldn't find entity name: osd.5 2016-11-03 18:31:27.339803 7f7138d28700 0 cephx server osd.7: couldn't find entity name: osd.7 So how do I tell the mon about the OSDs? Any pointers are greatly appreciated. -- Tracy Reed
