Even though the messages don't contain "warning", and probably should, they are printed via DMWARN(). These warnings are a function of device-mapper now being topology-aware. This means that your LVs are likely misaligned relative to the underlying hardware. Given that you're using partitions I'd wager they are the source of the misalignment. But there could be a bug lurking somewhere. Please provide the output from the following commands: pvs -o +pe_start cat /sys/block/sda/sda6/alignment_offset cat /sys/block/sda/queue/physical_block_size cat /sys/block/sda/queue/logical_block_size If you could also provide the same info for all other PVs that are in the VG that would be appreciated.
