Hi,
I'm testing multinode cluster with several cinder-volume instances. The
latter are configured with iSCSI storage (ZFSSA). To enable HA of
cinder-volume I had to specify 'host' option, otherwise volumes will be
bound to a specific host (only good for LVM driver). This works so far
but I am concerned about reported issues like race conditions:

Is Active / Passive requirement for non-local (iSCSI-like) backends
still valid? I also see 'cluster' option for A/A which still is 'not
supported':

Thanks,
