Hi Rutger,

> tmp/guix-build-ceph-12.0.2.drv-0/td/t-7201/dev/osd0/current
> ID 1745 gen 819598 top level 257 path
> tmp/guix-build-ceph-12.0.2.drv-0/td/t-7201/dev/osd0/snap_1

Does that mean that wiping out /tmp/guix-build-ceph-*, as happens when
build finishes, isn’t enough to get rid of those volumes?
