can't initialize OpenStack storage driver in CoreOS

[scotthz]

When initializing the OpenStack storage driver, REX-Ray tries to execute /usr/sbin/dmidecode, which is not available in CoreOS. As a result,

DEBU[0000] error initializing driver                     driverName=Openstack error.provider=Openstack 
error.cmd.Path="/usr/sbin/dmidecode" error.cmd.Args=[/usr/sbin/dmidecode] error.cmd.Out=[]

CoreOS version:

DISTRIB_ID=CoreOS
DISTRIB_RELEASE=835.9.0
DISTRIB_CODENAME="Red Dog"
DISTRIB_DESCRIPTION="CoreOS 835.9.0"

Is there a more cloud-friendly way of getting the OpenStack instance id?

[clintkitson]

Great question. Going to have to do some research on this one. Worst case
an option could be added for the driver that allows you to bypass
introspection and specify the instance id manually.

@scotthz Have you found any more information related? I spent a few minutes but have not come up with a better answer so far. I wonder if dmidecode is something that could be installed in another location?

[scotthz]

@clintonskitson I looked briefly for another method to find openstack id but didn't find anything. Worked around it for now to meet my current need.

Post-cloud-init, /bin, /sbin, /usr/bin, usr/sbin are all on a read-only filesystem in CoreOS. It occurred to me that they might be writeable during cloud-init. If so, it dmidecode could be written to usr/sbin when the VM is created. But that would probably break down when CoreOS updates itself.

/etc is writeable, but rexray would know to look there in the event that it finds itself running on coreos or /usr/sbin/dmidecode doesn't exist.

Or maybe the coreos people could add dmidecode to their distributions.

Hi @clintonskitson, I have similar issue. Any workaround on this?

Thanks

[clintkitson]

@CBR09 Marking this as an enhancement request. We will look at making the bin file configurable. For now you could checkout ff03583 and modify the path and build.

[CBR09]

Thanks @clintonskitson, Allow changing bin file config is good, now, I've build rexray in container and it works

@clintonskitson: Impossible for me to build ff03583, I get this error

Could you provide me with more details in order to get rid of this bug...

I am not familiar with go compilation. I tried to follow build-reference but with no success.
I you have any ressources that could help me.

Thanks by advance
Bertrand

[clintkitson]

It looks like you go version is likely not 1.5.x?

[bretif]

@clintonskitson You are right I was using a go version < 1.5

I just tried with go 1.6.1, but I stil get an error:

Closing due to inactivity. OpenStack can be revisited if new openstack driver is merged via https://github.com/codedellemc/libstorage/issues/182
