[Openstack] [Cinder] Cinder snapshots

2012-11-08 Thread Avishay Traeger
Hi all, I had a few questions about snapshot support in Cinder: 1) a. Why is a snapshot a fundamentally different entity than a volume? b. Is it because some back-ends don't support the same set of operations on snapshots? c. Is this what the snapshot-to-volume operation was meant to achieve

[Openstack] Potential security issue with CHAP

2012-11-29 Thread Avishay Traeger
Hi all, Currently, CHAP secrets are managed by Cinder, and passed to Nova for use when attaching volumes. This means that unless the communication is encrypted, or a separate trusted network is used, CHAP secrets can be sniffed on the wire. Opinions? Thanks, Avishay ___

Re: [Openstack] Error while creating cinder volume

2013-01-20 Thread Avishay Traeger
Vibhu, What Cinder did here is: 1) Downloaded the qcow2 file to /tmp 2) Tried to convert the qcow2 file to raw (reading from /tmp and writing to the logical volume) The problem is that your image takes more space with raw format, and that is why it is failing. Basically, qcow2 does not allocate s

-1 I'm sorry to do that, and it really has nothing to do with Ollie or his work (which I appreciate very much). The main reason is that right now Cinder core has 8 members: 1. Avishay Traeger (IBM) 2. Duncan Thomas (HP) 3. Eric Harney (RedHat) 4. Huang Zhiteng (Intel) 5. John Griffith (Soli
