Hello Everyone, Since the sub-LV #0 has errored, LVM will not let me activate the logical volume. Is there a way to remap the #0 sub-LV to the replaced disk or resizing the RAID6 to one less disk?

I first did a pvcreate and then a vgextend. I was using the —rebuild option because I know which physical drive is bad. In the lvmraid man page it says —repair might not know which is the correct block to use so to use —rebuild.

Also, are you sure that --rebuild is the correct operation? man 7 lvmraid suggest you might want --repair or --replace instead.
