Bare Metal CoreOS - Installing on multipath

[Andreas Krüger]

Hi all,

I have a complete HP 3par SAN storage system with 14 HP blades connected to it. Each blade has multiple fiber channels where the LUN are exposed, so the blade has multiple ways to read/write from or to the SAN.

So I've been playing around with installing CoreOS on our SAN using multipath, but it seems not to work for me. First of all, the coreos-install script checks the disk type for either disk|loop|lvm . But when you use a multipath device, this type is mpath.

Second, if I add the mpath to that check, the installer fails when it wants to notify about the partitions.

So. I was wondering if any has installed CoreOS on baremetal with multipath support or if it's even supported?

I'm facing the exact same issue - our hardware setup is extremely similar to the situation described by Andreas above (Blade machines with no internal HDD's, booted from a SAN target).

Containers provide excellent isolation, so I want to avoid adding any additional overhead in the form of a hypervisor (that could handle the mpath device) if there is a better way.

Thanks!
