I am expanding my raid6 array from 18x2Tb to 20x2Tb disks and after 3 weeks status shows:
Logical device Task: Logical device : 0 Task ID : 105 Current operation : Reconfiguration Status : In Progress Priority : High Percentage complete : 11 <——— !!?
I.e. I need to wait another 30 weeks for it to complete... Is there any way I can cancel expansion and revert the array to its original state?
From my past experience adding just 1 drive to the same array took only 3-4 days, I never expected that 2 drives would take that much longer.
