Create Volume from Image Failing on non-LVM Configuration

[Joe T]

Hello,

I'm currently using Folsom. I haven't tested if this still exists in Grizzly.

I was able to successfully create a volume from a Glance image by using the standard LVM Cinder configuration. However, it fails immediately in my other environment which uses the NetApp iSCSI driver:

I'm not sure why it's trying to reach the volume under /dev/mapper -- it sounds like Cinder is falling back to a default function?

Please let me know if you need further information.

Thanks,
Joe

Hey Joe,

In Folsom this currently only works on LVM and Ceph. Hoping to have a backport for the general iSCSI case soon.

Hi John,

Thanks for the quick reply. If there are plans for a backport, then is it safe to assume this is fixed in Grizzly?

Thanks,
Joe
