Hi, we're using rbd for VM disk images and want to make consistent backups of groups of them. I know I can create a group and make consistent snapshots of all of them: # rbd --version ceph version 14.2.9 (581f22da52345dba46ee232b73b990f06029a2a0) nautilus (stable) # rbd create test_foo --size 1M # rbd create test_bar --size 1M # rbd group create test # rbd group image add test test_foo # rbd group image add test test_bar # rbd group snap create test@1 But how can I export the individual image snapshots? I tried different ways of addressing them, but nothing worked: # rbd export test_foo@1 - error setting snapshot context: (2) No such file or directory # rbd export test_foo@test/1 - rbd: error opening pool 'test_foo@test': (2) No such file or directory # rbd export rbd/test_foo@test/1 - error setting snapshot context: (2) No such file or directory # rbd export test@1/test_foo - rbd: error opening pool 'test@1': (2) No such file or directory # rbd export rbd/test@1/test_foo - rbd: error opening image test: (2) No such file or directory Am I missing something?
