Hi, Devs: We all know how (anti)-host affinity group works in CloudStack, I am wondering if there is a similar concept for (anti)-storage affinity group?
The use case is as this: in a setup with just one (somewhat) unreliable primary storage, if the primary storage is off line, then all VM instances would be impacted. Now if we have two primary storage volumes for the cluster, then when one of them goes offline, only half of VM instances would be impacted (assuming the VM instances are evenly distributed between the two primary storage volumes). Thus, the (anti)-storage affinity groups would make sure that instance’s disk volumes are distributed among available primary storage volumes just like (anti)-host affinity groups would distribute instances among hosts. Does anyone else see the benefits of anti-storage affinity groups? Yiping
