[one-users] Ceph image creation works ... but disk is empty (ONE 4.6 beta)

[Jaime Melis]

Hi Stefan,

bug confirmed, and (hopefully) fixed.

Can you try with this  patch:
https://github.com/OpenNebula/one/commit/d44e5be354c8d7b3d8bf23a3875a3b08b49ee776

That should be applied on /var/lib/one/remotes/downloader.sh (and run
onehost sync).

Please let me know if after applying this patch it works for you. Great
catch, btw :)

cheers,
Jaime
