Resolve parted partition when the resulting partition is not properly aligned for best performance alarm

The operating system's SDB and SDC need to be expanded to the original partition in an LVM manner, and since it is a 3T disk, Fdisk is no longer available and can only be made in GPT format with parted.

Parted/dev/sdb

Mklabel GPT

When using the Mkpart command, there is an alarm:

The resulting partition is not a properly aligned for best performance

Google a little bit, find a solution, mark.

# cat/sys/block/sdb/queue/optimal_io_size1048576

# cat/sys/block/sdb/alignment_offset0

(1048576 + 0)/ 2048

Use this formula to derive 2048

So you can create it with this command.

Mkpart Primary 2048s 100%
