makes no difference:
gzip -dc vm-101-disk-1.img.gz | rbd import --format=2 --size=40960 - 
kvmpool1/vm-101-disk-1
rbd: error reading file: (29) Illegal seek
Importing image: 0% complete...failed.
rbd: import failed: (29) Illegal seek

I think the problem is that ceph seeks in File when it get's zeros (not 
filled content). But seeking doesn't work on stdin. It has to read from 
stdin until there are no more zeros.
