>>Thanks Alexandre, so you are confirming that this exact case misbehaves? The rbd_cache value from ceph.conf always override the cache value from qemu.

I don't known what happen in a live migration for example, if rbd_cache in ceph.conf is different on source and target host ? ----- Mail original ----- De: "Andrey Korolyov" <andrey@xxxxxxx> À: "aderumier" <aderumier@xxxxxxxxx> Cc: "Jason Dillaman" <dillaman@xxxxxxxxxx>, "ceph-users" <ceph-users@xxxxxxxxxxxxxx> Envoyé: Mardi 9 Juin 2015 10:36:09 Objet: Re: rbd cache + libvirt On Tue, Jun 9, 2015 at 7:59 AM, Alexandre DERUMIER <aderumier@xxxxxxxxx> wrote: > host conf : rbd_cache=true : guest cache=none : result : cache (wrong) Thanks Alexandre, so you are confirming that this exact case misbehaves? _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
