the weird thing is that I have some volumes that were created from a snapshot, that actually boot (they complain about not being able to connect to the metadataserver (which I guess is a totally different problem) but in the end, they come up.
I haven't been able to see the difference between the volumes…. I re-snapshotted the instance whose volume wouldn't boot, and made a volume out of it, and this instance booted nicely from the volume. weirder and weirder… /jc -- SWITCH Jens-Christian Fischer, Peta Solutions Werdstrasse 2, P.O.
