Re: VDP disk expansion in VDP 6.1.2 failing.

Hi

I also have similar issue , the issue got resolved by changing configuration file

1. Use Vi to open file under /usr/local/vdr/etc/vdr-configuration.xml
2. Edit that file and changed <numberOfDisk>3</numberOfDisk> to <numberOfDisk>6</numberOfDisk> ( If you expanding from 4TB change 3 to 6, if you are expanding 6TB change same 9) 
3. Try to expand the appliance again.
