Build. Align partition

When using parted to create disk partions you may recieve the following warning message

Warning: The resulting partition is not properly aligned for best performance

Th parameters required to align the partition should be found in the physical disk device files.

The parameters for the block device sdb, can be retrieved with the following commands

cat /sys/block/sdb/queue/optimal_io_size

cat /sys/block/sdb/queue/minimum_io_size

cat /sys/block/sdb/queue/physical_block_size

cat /sys/block/sdb/alignment_offset

To calculate the sector on which to align the partition

optimal_io_size + alignment_offset / physical_block_size

For example, an SD card with a 512 byte block size

512 + 0 / 512 = 1

The parted command to create the partition using all available space, is then 

mkpart primary 512s 100%
