If you proceed, more > disks might pop out due to errors. Well, sort of. A significant fraction of the data is now striped across 12 + 0 drives, rather than 11 + 1. There are no errors occurring on the drives, although of course an unrecoverable error could happen at any time. > It's best to backup your data, run a check on the array, fix it then The data is backed up.

The array is in good health, other than the two kicked drives. I'm not sure I understand what you mean, though. I'm asking about the two offline drives. Should I add the 13th back? It still has substantially the same data as the other 12 drives, discounting the amount that has been re-written. If so, how can I safely stop the array re-shape and re-add the drive?
