CoreOS - Raid1 /var/lib/data wont boot after boot

Excellent. It would appear that zeroing the superblock did the trick, and that creating the partition in some other way may have caused a problem.
Glad you have it solved.

yes, i think that was the problem, stoked to have it resolved :sweat_smile:

thanks so much for the assistance, yours and others suggestions were essential to getting everything working. Fedora community rocks! :metal:

Now everything is up I am loving how simple CoreOS is as a home server… I have a single, simple yaml file that describes a bare-metal install of a server with 2 raid arrays plus other storage, which will start a docker-compose described list of containerised services… installed within minutes from scratch… so awesome!
