Kindly advise
Hi Salman, You don't mention the cinder driver or anything, so I'm going to assume you are using the LVM driver with default's cinder-volumes VG (Volume Group) on the bare disk (no partition). If that's the case, you'll need an additional disk (or loopback device), create a PV (Physical Volume) on it, and add it to the cinder-volumes VG. Fortunately the LVM command that extends a VG can do the PV creation automatically, so if for example you have added /dev/sdc to your system and you want to use it for Cinder volumes you can: - First check the current status of the VG: $ sudo vgs - Add the device: $ sudo vgextend cinder-volumes /dev/sdc --debug - Confirm the VG has grown: $ sudo vgs Cheers, Gorka.
