Hello,

I'm planning to use cinder as glance store.
And, I'll setup cinder to connect storage by iSCSI multipath.

In this case, can I run glance-api and cinder-volume on the same node?

In my understanding, glance-api will attach a volume to own node and
write a uploaded image to the volume if glance backend is cinder.
I afraid that the race condition of cinder-volume's iSCSI operations
and glance-api's iSCSI operations.
Is there possibility of occurring it?
