Well, there are two ways to run Ceph on btrfs. One is to give it a raw partition and tell it to set up the partition itself. I'm not sure how difficult it would be to enable these features under that situation, although I think it would be pretty simple. The other way is to just create a btrfs filesystem and point the OSD at a directory on that filesystem as its backend storage. In that scenario you can set whatever mount options etc that you like. I'm not personally that familiar with btrfs but I imagine this should let you enable whatever options you like. :) -Greg -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
