Now I am confused by a strange issue, seems the issue has been asked before by google but no a clear answer for it. The specific details as below-- in the client side, I want to create a rbd image, so I run the commands: root@~# ceph osd pool create mypool 100 100 pool 'mypool' created root@~# rbd ls -p mypool odm-kvm-img root@~# rbd --image odm-kvm-img info rbd: error opening image 2013-04-24 10:43:42.800917 7fdb47d76780 -1 librbd::ImageCtx: error finding header: (2) No such file or directoryodm-kvm-img: (2) No such file or directory So I tried those steps followed according the goolged: root@~# rados ls -p mypool odm-kvm-img.rbd rbd_directory root@~# rbd info odm-kvm-img.rbd rbd: error opening image 2013-04-24 10:54:19.468770 7f8332dea780 -1 librbd::ImageCtx: error finding header: (2) No such file or directory odm-kvm-img.rbd: (2) No such file or directory odm-kvm-img.rbd is showed by 'rados ls' command and it's there, but why I get an error when run the 'rbd info' command upon odm-kvm-img.rbd? does anybody can be help about this?
