<div dir="ltr"><div><div><div>So, it's up and running now.<br><br></div>Next step would be to configure ovirt to use the new gluster volume.<br><br>And for backups to be moved from linode to this area instead.<br><br></div>
Please note I only allocated 1 TB to glusterlv, and 100 GB to backuplv, This leave ~700 GB untouched for allocation where we need it.<br><br></div>"It's better to grow then to show" ... I just thought of that one, I know its bad. Sorry :-D<br>
