Hi Stefan, This is not a Gluster4 series, it is a design choice. This is the same behavior in 3.x series also. When you restore a volume, we cannot use the old path. Because we are not sure about the path at time when we restore the volume. I will explain with an example. Let's say you have 1*3

Re: [Gluster-users] Tiering and sharding for VM workload

Yes, you are correct. On a sharded volume, the hot and cold would be based on sharded chunks. I'm stressing the point which Krutika mentioned in her mail that we haven't tested the use case in depth. Regards Rafi KC On 09/06/2016 06:38 PM, Krutika Dhananjay wrote: > Theoretically whatever you
