Subject: difference between qemu cache settings and ceph.conf rbd cache settings?
Date: Tue, 19 Jun 2012 08:37:41 +0200	[thread overview]
Message-ID: <4FE01E35.1080002@profihost.ag> (raw)

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
