Hi, this is Michael, I work at ClusterHQ. We don't support running Flocker with a Google persistent disk backend yet, but would like to. If you add that idea here, it will help us prioritize https://feedback.clusterhq.com/forums/305266-feedback-for-fl...

Doesn't appear to support it, but the source is on github and in theory they're just a different google-flavoured ebs.

Yep, someone would need to write a Flocker storage driver for GPD, that's all. Could be us, could be the community. We have docs on building drivers: https://docs.clusterhq.com/en/1.3.0/gettinginvolved/plugins....
