Open Stack

Hallo Khanh Nguyen,

Thank you very much for taking the time to give me an answer.

So if I understand you correctly I can mount an iSCSI or NFS export from an external storage device into the cinder host and let cinder use that to create its own iscsi block device which can then be exported further.

Is it also possible that this cinder iscsi block device can also be imported by a host that I did not create with openstack, let's say an existing ubuntu physical host which I already have for two years? If yes, how would I go about that.

High regards,

Randy

Hi Randy,
Openstack’s operations bases on the installed hypervisor. First, you need to know exactly your hypervisor that is supporting which types  of back-end storage.  After that, you can select one  back-end storage system corresponds to your system. Cinder is just an front-end to help vms can connect to an back-end storage behind. Cinder supports so much driver to connect to back-end storage system such as: NFS, Ceph, GlusterFS, LVM ,… If you have a back-end storage which cinder hasn’t supported yet driver to connect to, you can create a middle mount-point by using  NFS, ISCSI to help cinder can operate on them J.

Subject: [openstack-community] usage of openstack information Hi all, I have been reading up on openstack as I am completely new to this. I have set up some test systems according to manuals found here and there.Now, I have a question about the possible use of openstack storage.I have seen that the normal provisioning of storage is meant to be for vm's created within openstack itself. This can then be block storage (cinder) or object storage. Can somebody tell me if it is possible to use openstack to provision the same kind of storage to physical servers which are otherwise in no way connected to openstack or virtual machines created in systems like vmware? I hope somebody can asnwer me this and maybe point me the way to test something like this. Thanks in advance, Rgds, Randy
