If with raid6 a disk fails, a automatic recovery is done with one
missing disk. With raid6 two disk may fail and the raid can be
recovered. If you add a good disk, after the recovery a resync is done
with state UUU_. Only after this resync it will get into state UUUU
again. This resync should generate a warning.
