Hi, We are currently in the process of evaluating sheepdog to use as a backend storage for our virtual environement. But right now I am facing really poor performances on unallocated bloc. It litterraly takes hours to convert a 5G file. So I am mounting the partition with different option without any luck /dev/sdd1 on /var/lib/sheepdog type ext4 (rw,noatime,user_xattr,barrier=0,data=writeback,nobh) Started sheepdog with sheep -p 7000 -l 0 /var/lib/sheepdog When I issues qemu-img convert /images/debian60-64bits.qed -O raw sheepdog:debian60-64bits It takes hours to finish altought it is just 5G img. The performance from within the virtual machine is then fine. and close to raw performances. Is there something I am doing wrong ?
