[ceph-users] Nautilus block-db resize - ceph-bluestore-tool

Hello, Based on other discussions in this list I have concluded that I need to add NVMe to my OSD nodes and expand the NVMe (DB/WAL) for each OSD. Is there a way to do this without destroying and rebuilding each OSD (after safe removal from the cluster, of course)? Is there a way to use ceph-bluestore-tool for this? Is it as simple as lvextend? Why more NVMe? Frequent DB spillovers, and the recommendation that the NVMe should be 40GB for every TB of HDD. When I did my initial setup I thought that 124GB of NVMe for a 12TB HDD would be sufficient, but by the above metric it should be more like 480GB of NVMe. Thanks. -Dave -- Dave Hall Binghamton University kdhall@binghamton.edu
