Re: [cinder] setting `rbd_exclusive_cinder_pool = True` with multiple cinder-volume writing to the same pool

Hi,

Just doing a quick sanity check - I can set `rbd_exclusive_cinder_pool = True` (in pike, where the change landed first) even if more than one cinder-volume is writing to the same Ceph pool, right? Assuming nothing writes to the pool outside of cinder, we should be good as far as I understand the code.

Hi Chris, It's best not to share your pools, but your assessment is correct regarding the rbd_exclusive_cinder_pool configuration option. The code ruled by that option will work as expected even when sharing the pool between different cinder-volume services. Cheers, Gorka.
