[Gluster-devel] [Gluster-users] Fwd: Re: GlusterFS removal from Openstack Cinder

Tue May 30 04:43:09 UTC 2017

Hi everybody,

I suppose there will be a lot more people affected by removal of the
driver from Cinder who do not know about it. I am running production
clusters on Mitaka and Newton and did not know about the issue -
Openstack is quite a beast to keep pace with the updates.

Are there any news from dev team, Red Hat or Amye's radar?

-ps
