Ah, you're right — I don't think that doc has been correct since before argonaut, but prior to ~v0.55 it wouldn't complain on non-UUID values. The basic "ceph osd create" call simply allocates a new OSD ID and bumps the max allowed, and returns the new ID back to the caller. If you also specify the UUID, then it will check and see if that UUID already exists and simply return the allocated ID if it does (otherwise, create a new one as before). In argonaut, there's a bug that will silently ignore any non-UUID extra arguments, which is what was happening with those IDs. John, can you fix this in the docs please? :) -Greg (All this is assuming I've got my commit dates right; if not there might be a bit of variation about when which version took effect.) > I've already added osd.61,62,63 and 64 to ceph.conf > > Greets, > Stefan > Am 12.12.2012 22:41, schrieb Gregory Farnum: >> >> Yeah; 61 is not a valid UUID and you can't specify anything else on that >> line. >> >> On Wed, Dec 12, 2012 at 1:38 PM, Stefan Priebe <[email protected]> >> wrote: >>> >>> HI Greg, >>> >>> sorry just a copy & paste error. >>> >>> [cloud1-ceph1: ~]# ceph osd create 61 >>> (22) Invalid argument >>> >>> >>>> Read those two lines again.
