hi,all now, rbd can only use erasure code pool with cache tier. If we want to use rbd + ec, without cache tier, that means all rbd operations should be rollback, after trace the rbd code, there are many tmap\omap ops which not supported by ec. can i replace the omap operations to xattr, does it works? and for rbd kernel module,what should be done to support rbd +ec? By the way, what's main difference between xattr and omap? bc the omap performance is better when storing larger bytes? -- thanks huangjun -- 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
