Hi All,

I have a question about cinder.
Can I run cinder-volume and cinder-backup on a same host?

I use a cinder driver that uses iscsi protocol.
I afraid that iscsi operations will be conflicted between cinder-volume and cinder-backup.

e.g.(Caution: This is just a forecast.)
If cinder-backup execute "iscsiadm -rescan" while cinder-volume is terminating connection,
the iscsi connection will remain unexpectedly.

Is there a model architecture?
Please share knowledge if you have it.
