FYI
I just resized copr-be storage for DNF repos from 4TB to 6TB.
It was as easy as:
umount /var/lib/copr/public_html
systemctl stop var-lib-copr-public_html.mount
copr-backend-service stop
systemctls stop lighttpd.service
in openstack dashboard, detach the volume, click "enlarge volume", set it to 6000GB.
attach it back.
Again:
umount /var/lib/copr/public_html
systemctl stop var-lib-copr-public_html.mount
parted
