I'm unable to complete a multi-region(eu) snapshot for a particular disk in europe-west2. It takes over an hour to timeout and then returns an "Unknown Error". I have managed to snapshot this disk in a single region.
I've been able to get a multi-region snapshots working for other disks in the same region.
I've also tried various different options:
Stopped all services umounted the disk powered off vm
none of which seem to help. Has anyone ever experienced this before?
