[ceph-users] ceph-osd/bluestore using page cache

Some years ago when first switching to Bluestore, I could see that ceph-osd wasn't using the host page cache anymore. Some time later after a Ceph upgrade, I found that ceph-osd was now filling the page cache. I'm sorry I don't remember which upgrade that was. Currently I'm running pacific and reef clusters. Should ceph-osd (Bluestore) be going through the page cache? Can ceph-osd be configured to go direct? Thanks. -- - Brian
