Hi Everyone. I'm "new" to Ceph, only been administrating a cluster for about a year now, so there is a lot more for me to learn about the subject. The latest concept I've been looking into is Cache Tiering. I added it to my home cluster without a problem and didn't see a degradation in performance, and it seemed just to work. The documentation is pretty straightforward to follow. First, add a hot pool and then enable the tier and overlay for that hot pool. Then configure a bunch of values, and it will do its thing. In our production environment, we are running the hot pool, a lot of NVME disks with low latency. But as we work with a lot of archival data, it would be nice to move it over to spinning disks for a long time archive. How do I add cold storage to a running cluster without disrupting the current operation? Thank you for reading my email.
