Hi,
[client] rbd cache = false rbd cache writethrough until flush = false
this is the rbd client's config, not the global MON config you're reading here:
# ceph --admin-daemon `find /var/run/ceph -name 'ceph-mon*'` config show |grep rbd_cache "rbd_cache": "true",
If you want to change the global "rbd_cache" setting you have to change that in the [global] (or maybe [mon]) section. But I'm not sure which effect this will have.
If you want to change global (librbd) settings, please use "rbd config global set ..." (which is just a wrapper around "ceph config set global ..."). The conf files only apply to the single host where they exist.

Zitat von Philip Brown <pbrown@medata.com>:
Oops.. sent this to the "wrong" list previously. (lists.ceph.com) Lets try the proper one this time :-/
not sure if this an actual bug or I'm doing something else wrong. but in Octopus, I have on the master node
# ceph --version ceph version 15.2.7 (88e41c6c49beb18add4fdb6b4326ca466d931db8) octopus (stable) # tail -3 /etc/ceph/ceph.conf [client] rbd cache = false rbd cache writethrough until flush = false
but I have restarted ALL nodes.. and yet rbd cache is still on.
# ceph --admin-daemon `find /var/run/ceph -name 'ceph-mon*'` config show |grep rbd_cache "rbd_cache": "true",
What else am I supposed to do???
