ReadyNAS 424 XRAID Not Expanding
I was running 4x10TB (XRAID/RAID 5). I replaced two disk with 14TB so that the configuration is 2x10TB and 2x14TB. Resync completed, but volume size is the same as before installing the larger disks at 27TB. I expected 31TB after expansion. Logs indicate that it tried to expand but the only error I see is:
ERROR: sdd sectors < 0 (-22)
after which, it tries to expand again but no errors.
Any ideas?
Thx.

If it's already on, partitions.log may also be helpful.
