Hi Everyone, I am running a containerized pacific cluster 15.2.15 with 80 spinning disks and 20 SSD. Currently the SSDs are being used as a cach tier and holds the metadata pool for cephfs. I think we could make better use of the SSDs by moving block.wal and block.db to the SSDs and I have a few questions about this.
* How do I change my config to hold block.db and block.wal? Do I need to fail out drives and then re-create them? What is the proper procedure for this? * How do I determine the number of spinning drives that can share one SSD? * Is this a good idea? Am I likely to see a performance increase – what kinds of workflows will benefit from this change? Thanks for your help!
