I'm confused. Since devmapper always uses 512 byte sectors, what does the sector size of the underlying physical disk have to do with anything ( other than alignment )? We're only dealing with devmapper. > + *start *= (part->disk->dev->sector_size / > PED_SECTOR_SIZE_DEFAULT); + *length *= > (part->disk->dev->sector_size / PED_SECTOR_SIZE_DEFAULT); Since the sector size reported by device mapper is always 512 bytes, these statements are effectively no-ops ( 512 / 512 is always 1 ). -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.17 (MingW32) iQEcBAEBAgAGBQJU1OS0AAoJENRVrw2cjl5Rbg4IAJ89Abv8kPJGqjLXTsmOe38C Idkyi7dzo9C7+XvTbZ7SxHkyJ3htmdzPhD6eyq311YKSOdbqsPErFtxPWGFshyA2 aaFvRtaUKrA01tqyUwoLaVhBIOh2Z5tB0+GDgvR8/5qFwEifszq4TGuI8Zca78KS dGqXesGV4Jxcu4+RFXvJW1sOfxTOIzoR70iVyiJTud5J2zrxFWt0c7iKpKq/ET8f lMGCui3c8rNwmQYWJoWAf/78rw1ugUpUxO8/MfVPtVV4EId8QxSOrXfI6ICuACzt Ap0yYjWRQgajX6PutJOYzY7AlKX37NE/cE9fkO9JhvS2KEkA+MM6bVo6J/VS3Ks= =n52R -----END PGP SIGNATURE-----
