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


This does not work but:
rbd snap create kvmpool1/vm-113-disk-1@BACKUP

works fine. Thanks!

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?


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.

I don't have access to a running Ceph cluster now to verify this.
