Hi Lars,
the output of those commands:
root@nas3:/# cat /sys/block/sdb/queue/physical_block_size
4096
root@nas3:/# cat /sys/block/md0/queue/physical_block_size
4096
root@nas3:/#
The strange thing here is that dmesg is not poluted with sata errors
like it is usual when a hard disk has bad sectors or some other
hardware problem. the only thing in dmesg that hints to why reading
the md volume fails are from dm itself.
Cheers
Pedro

Hi Pedro,
maybe an issue with the logical/physical blocksize?
What tell these commands:
cat /sys/block/sdb/queue/physical_block_size
cat /sys/block/md0/queue/physical_block_size
Seagate says there are 4096 bytes/sector on this devices.
Lars
