Bug Description

After activation of additional disks in the raid controller Fuel shows a wrong disk setup and cannot be changed.


1.) Setup a compute node with storage (lvm). Only 2 disk are active (300gb)
2.) Activate additional disks (6.5TB)
3.) The shown disk layout for the node changed. It looks like that the newly added disks are used for LVM.

But this is not the case:

# lvm vgs
  VG #PV #LV #SN Attr VSize VFree
  cinder 1 1 0 wz--n- 112.41g 111.41g
  image 1 1 0 wz--n- 112.41g 32.00m

You activated disk after node was provisioned?

I think if you will re-provision node with all disks activated before provisioning - the will be no such problem.
But i understand that this may be not an option.

Yep, at the end we had to reprovision the whole environment.

But anyway, the bug is about displaying the wrong disk setup in the web interface. So we see all logical disks been used but in reality it's just using the first raid.

Our current solution here is to disable update of disk info in nailgun after deployment. In future we will think how to deal with hardware changes in a better way.
