This is strange, because it seem to be fixed a long time ago(I have seen some redhat bugzilla from 2011 about it) But I don't have hardware to test it :( I'll look in my archives tomorrow ;) ----- Mail original ----- De: "Dietmar Maurer" <[email protected]> À: "Alexandre DERUMIER" <[email protected]>, [email protected] Envoyé: Jeudi 8 Novembre 2012 17:50:58 Objet: RE: [pve-devel] new cache benchmark results > Note : with shared storage, with writeback, I generally see big spike (faster > than cache=none), but after big slowdown (near zero) during 5-10s. > So I think this is when the host need to flush the datas, it add more > overhead. (maybe network latency have an impact...) Another problem with cache=none is that it does not work with 4K sector drives. User reported problems with 4K iscsi and 4K local disks. Any idea how to solve that? _______________________________________________ pve-devel mailing list [email protected] http://pve.proxmox.com/cgi-bin/mailman/listinfo/pve-devel
