Can you add "debug rbd = 20" your ceph.conf, re-run the command, and provide a link to the generated librbd log messages?

Thanks,

Subject:  hammer (0.94.1) - "image must support layering(38) Function not implemented" on v2 image

Hello,

I'd like to ask about another problem I've stumbled upon..

I've got format 2 image + snapshot, and while trying to protect snapshot
I'm getting following error:

[root@vfnphav1a ~]# rbd ls -l ssd2r
NAME                            SIZE PARENT FMT PROT LOCK 
fio_test                       4096M          2           
template-win2k8-20150420      40960M          2           
template-win2k8-20150420@snap 40960M          2           

[root@vfnphav1a ~]# rbd snap protect ssd2r/template-win2k8-20150420@snap
rbd: protecting snap failed: 2015-04-20 16:47:31.587489 7f5e9e4fa760 -1 librbd: snap_protect: image must support layering(38) Function not implemented


am I doing something wrong?

thanks a lot in advance for reply

BR
