New issue 1056 by [email protected]: gnt-backup with RBD, export config only
https://code.google.com/p/ganeti/issues/detail?id=1056

What software version are you running? Please provide the output of "gnt-
cluster --version", "gnt-cluster version", and "hspace --version".

2.12.1

What distribution are you using?
Debian Jessie

What steps will reproduce the problem?

See:
https://groups.google.com/forum/#!topic/ganeti/-ZcsTLnE3nk

What is the expected output? What do you see instead?

Please provide any additional information below.

Aside from having RBD correctly supported with gnt-backup (even in a limited fashion), there is a more generic feature request that would help with this and similar unsupported (non-LVM) storage systems.

As per the thread above, add a switch to export to just generate the "config.ini" file for the instance in question. That file is human readable and easily edited, so the name of a manually created disk copy can be entered.

However for this to work fully, the import part of gnt-backup will also need a switch to NOT expect a LVM snapshot but something like a full image dump. Alternatively, being able to specify an already populated image (in the case of RBD having exported it and imported it manually) instead of backup would be also quite helpful. And probably handy in other use cases.
