Data corruption occurs on RAID 10 reshape on top of VDO with el7 kernel.
RAID 10 reshape (with both LVM and
mdadm
) on top of VDO corrupts data and can eventually trigger the raid10.c:1011 kernel bug. Stacking RAID 10 (or other RAID types) on top of VDO does not take advantage of the deduplication/compression capabilities of VDO and is not recommended. (BZ#1528466, BZ#1530776)
