Hi Amudhan, Please go through the following that would clarify up-gradation concerns from DHT to RIO in 4.0 1. RIO would not deprecate DHT. Both DHT and RIO would co-exist. 2. DHT volumes would not be migrated to RIO. DHT volumes would still be using DHT code. 3. The new volume creat

if doing an upgrade from 3.10.1 to 4.0 or 4.1, will I be able to access volume without any challenge? I am asking this because 4.0 comes with DHT2? On Thu, Nov 2, 2017 at 2:26 PM, Kaushal M wrote: > We're fast approaching the time for Gluster-4.0. And we would like to > set out the expected

Just so I am clear the upgrade process will be as follows: upgrade all clients to 4.0 rolling upgrade all servers to 4.0 (with GD1) kill all GD1 daemons on all servers and run upgrade script (new clients unable to connect at this point) start GD2 ( necessary or does the upgrade script do this?)
