Hello list,
i tried to create a snapshot of my disk vm-113-disk-1:
[: ~]# rbd -p kvmpool1 ls
vm-113-disk-1
[: ~]# rbd -p kvmpool1 snap create BACKUP vm-113-disk-1
rbd: extraneous parameter vm-113-disk-1
[: ~]# rbd -p kvmpool1 snap create vm-113-disk-1 BACKUP
rbd: extraneous parameter BACKUP
What's wrong here?
Stefan

Use:
$ rbd -p kvmpool1 snap create --image vm-113-disk-1 BACKUP
"rbd -h" also tells:
<image-name>, <snap-name> are [pool/]name[@snap], or you may specify
individual pieces of names with -p/--pool, --image, and/or --snap.
Never tried it, but you might be able to use:
$ rbd -p kvmpool1 snap create vm-113-disk-1@BACKUP
I don't have access to a running Ceph cluster now to verify this.

This does not work but:
rbd snap create kvmpool1/vm-113-disk-1@BACKUP
works fine. Thanks!
