I will, thanks! > What is the pool replication configuration or ec-profile? How many nodes in the cluster? We're 3/2 replication, no ec. It's a three-node (small) cluster, 8 filestore OSDs per node, with an SSD journal (wear evel 75%) We will be using samsung PM833 bluestore of the same size (4TB spinners to 3.83GB PM833 SSDs) > Are you planning to remove all disks per server at once or disk by disk? I was planning to: - first add two SSDs to each server, and gradually increase their weight - then, disk-by-disk, replace the 8 (old) spinners with the 6 remaining SSDs > Will all new drives equal or increase the disk capacity of the cluster? Approx equal yes. The aim in not to increase space. MJ
