<div dir="ltr">Hi all,<div><br></div><div>I'm building out the sheepdog drivers for OpenStack Nova. In order to build ephemeral volumes for VMs we need to provision a vdi and format it with a labeled filesystem. I've gotten this to work with the sheepfs client on a reasonably sized cluster (20 nodes) and for a 10G volume, the format happens <1s. But the development cluster I have in Devstack is 3 nodes with -c local. In this scenario, sheepfs takes >5 min to format the filesystem.</div>
<div><br></div><div>So I am wondering, is there a better way to format a vdi? OpenStack currently makes use of standard tools or libguestfs. Does sheepdog support either of these?</div><div><br></div><div>Thanks,</div><div>
