Subject: [dm-crypt] Alignment issue with 4K disk

Hi,
I'm trying to setup an encrypted volume on an external disk which has 4k
physical sector size (with 512b logical sector size).
I've used various parted option (-a none / minimal / optimal) and various --
align-payload options to cryptsetup, but everytime I luksOpen the container, I
get a kernel log with:
janv. 04 22:25:04 scapa kernel: device-mapper: table: 253:4: adding target device sdb1 caused an alignment inconsistency: physical_block_size=4096, logical_block_size=512, alignment_offset=0, start=4194304
(argument for start= changes for different values of the --align-payload)
I'm not sure it's really serious, but any idea how to fix that?
Regards,
--
Yves-Alexis
