InvalidBlockDeviceMapping => snapshotId can only be modified on EBS devices (Fog::Compute::AWS::Error)

[David Kerr]

Howdy.

I'm trying to take a snapshot of the volumes on one instance and move them
to a new instance that I'm creating.

(think cloning a database server to a new environment for testing)

I get the snapshots created ok. but when I try to attach them to the new
instance I get the above error.

I've attempted to go the reverse route and attach the volumes after the
instance is created, and that sort of worked
(I got 1 volume out of the 3 i tried to attach) but I'd much rather have it
get created with the volumes.


@mysnapshot = Array.new

loop through snapshots{
if y['deviceName'] !~ /sda1/ # because i don't want the root device.
snap = $ec2.snapshots.new
snap.description = "hello"
snap.volume_id = y['volumeId']
snap.save
snap.reload
@mysnapshot.push({ 'DeviceName' => y['deviceName'], 'Ebs.SnapshotId'
=> snap.id , 'Ebs.DeleteOnTermination' => true })
end
}

server = $ec2.servers.create(
:image_id => 'ami-xxxxxxx',
:flavor_id => 'm1.large',
:ebs_optimized => 'true',
:block_device_mapping => @mysnapshot
[other stuff])

I suspect that my block_device_mapping is clobbering my root partition.
does that sound correct? assuming that i solve that does this look right?

Thanks

Could you open an issue at: https://github.com/fog/fog/issues?state=open

I think that will help me to get the right people pointed at it.

Thanks!

Do you have any instance store volumes mounted? Those are not EBS so trying to do anything EBS related with them will blow up

Hmm, I'm not positive about the root partition but that's the one i'm
skipping with !~ /sda1/

The other 3 are most definitely EBS.

I'm going to move this over to the github per Wes's suggestion.

Thanks!
