Hi, I have a storage system consisting of 4 bricks. All of them run CentOS-6.3, with gluster 3.3.1. Two of the servers are equipped with twelve 2-TB disks and two with twelve 1-TB disks (slightly older). I use this as a secondary, mirrored storage system, and now I would like to do two things: 1. Swap the disks in the nodes with 1-TB disks to 2 TB disks. 2. Put in infiniband on all the nodes. 3. Even though it is possible to resync all the data from the primary system I would like to save time by keeping the data on the two servers with 2-TB disks. My plan is: 1. Delete the volume. 2. Update the OS (to 6.4) on all four servers. 3. Build a new volume (this time with rdma), using two bricks with data and two without. 4. "Rsync" the missing data from the primary storage system. 5. Rebalance. Could there be issues with this approach, e.g., when building the new volume, will the data on the two underlying raids be visible?
