[Starlingx-discuss] cinder-volumes and nova-local on same disk throws an error?

[Marcel Schaible]

Hi,

when I try to setup our duplex config with the cinder-volumes and nova-local on the same nvm drive
I'll get the following error:

[root at controller-0 ~(keystone_admin)]# system host-pv-add controller-0 nova-local  d79a7560-d92a-4544-9788-1caab390cc66
Cannot use this partition. A partition (/dev/disk/by-path/pci-0000:0b:00.0-nvme-1-part1) on this disk is already in use by cinder-volumes.

[root at controller-0 ~(keystone_admin)]# system host-pv-list controller-0
