Now, the RBD support for primary storage knows limitations:
- It only works with KVM
- You are NOT able to snapshot RBD volumes. This is due to CloudStack
wanting to backup snapshots to the secondary storage and uses 'qemu-img
convert' for this. That doesn't work with RBD, but it's also very
inefficient.
RBD supports native snapshots inside the Ceph cluster. RBD disks also
have the potential to reach very large sizes. Disks of 1TB won't be the
exception. It would stress your network heavily. I'm thinking about
implementing "internal snapshots", but that is step #2. For now no
snapshots.
- You are able create a template from a RBD volume, but creating a new
instance with RBD storage from a template is still a hit-and-miss.
Working on that one.
I just pushed a fix for creating instances from a template. That should
work now!
