Memory usage is still quite high here even with a large onode cache!
Are you using erasure coding? I recently was able to reproduce a bug in
bluestore causing excessive memory usage during large writes with EC,

Indeed it shows ssd in the OSD's metadata.
"bluestore_bdev_type": "ssd",
Then I misunderstood the role of the device class in CRUSH, I expected the
OSD would actually set its settings according to the CRUSH device class.
I'll try to force the OSDs to behave like HDDs and monitor the memory
