Whether removing device_health_metrics pool is ok or not
Hi, Could you tell me whether it's ok to remove device_health_metrics pool after disabling device monitoring feature? I don't use device monitoring feature because I capture hardware information from other way. However, after disabling this feature, device_health_metrics pool stll exists. I don't want to concern HEALTH_WARN caused by problems in PGs of this pool. As a result of reading the source code of device monitoring module, it seems to be safe to remove this pool. Is my understanding correct? Thanks, Satoru

On my Octopus cluster I was running with a broken device_health_metrics pool (due to PG issues) for over a month with no other obvious ill effects. I finally removed and recreated it to make ceph stop complaining about it. Since then I have not seen any data written to the pool. I know this doesn't answer your question directly, but in my case removing the pool temporarily did not cause any harm. --Mike

Thank you for your quick response!
