Disk size does not match at all (ubuntu/VMWare)
Solution 1:
Well I managed to get it to extend the LV with
lvextend -l+100%FREE /dev/mapper/ubuntu--vg-ubuntu--lv -A n
:)
It was the autobackup that blocked the LV to extend because it was so full. So -A n
sets the autobackup to no in case somebody encounters the same problem.
