I think the AI here is, first of all, to stress test and find our current limitations. Then, we can think if we care about it or not. Allon, Isn't this a platform (lvm) limitation ? Do we have the answer for comment #1 ? (In reply to Gil Klein from comment #4) > Allon, Isn't this a platform (lvm) limitation ? There's been a world of change since RHEV 3.2 (RHEV 6.3) this was reported, both on the platform side and VDSM. We need to know the current limitations before escalating/redesigning/fixing/whatever > > Do we have the answer for comment #1 ? No, see above.
