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?
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.
