Hi, I know Itamar explained that the notion of master storage domain will disappear in some releases. But now, with a 3.4 I'm installing, I was wondering : - on my other oVirt setups, I started with one big (iSCSI) LUN, which is the master, and stored as many VMs I could - when space came to miss, I added another LUN, the another... - when I have to do some maintenance (grow, disable, other...) on a LUN, I can move my VM disks amongst the normal storage domains. When Empty, I can switch them off, add others, and so on The only one I can not play with is the master one. I came to think that I had no benefice storing anything on the master storage domain, and use only the normal storage domains. And then, I came to think I had no reason to dedicate a huge LUN for the master. Ok, but according to you, what is the minimum reasonable size for a master storage domain? -- Nicolas Ecarnot
