Hi, We went the „long“ way.
- first emptied osd node by node (for each pool), purged all OSDs - moved the OS from centos 7 to ubuntu 20 (reinstalled every node) - removed the cache pool and cleaned up some config - installed all OSDs and moved the data back - upgraded ceph nautilus to octopus (containered) and now we are moving to pacific/quincy. This worked (slow - lot’s of data) without any bigger outage or problems. The only thing was, that a pool of NVMe nodes was flooding other nodes while backfilling :) … … so start with low backfill values and CHECK before you carrie on with other pools or nodes. Best .
