ebsinit

This is a tool to quickly initialize AWS EBS.

EBS restored from a snapshot needs to be initialized for good performance. The method of using dd or fio is officially introduced as a way to initialize ESB. However, since these tools are not specialized tools for initializing EBS, there is room for improvement. EBS initialization can be achieved by reading only 512 bytes from each 512KiB block. This tool uses a high-speed system call io_submit(2) to read a small area for each 512KiB block. Using this mechanism, EBS can be initialized more quickly.
