Hello list, i've now patched my qemu to include the qemu cache settings for rbd. Now i can change my drive caching mode. But there are also these settings for global section in ceph.conf. rbd_cache = true rbd_cache_size = 33554432 rbd_cache_max_age = 2.0 How do they influence or replace each other? thanks Stefan
In qemu, the cache settings map to: writeback: rbd_cache = true writethrough: rbd_cache = true rbd_cache_max_dirty = 0 none: rbd_cache = false qemu's settings are overridden by any custom settings you have in a config file or on the qemu command line.
