README

Warm an EBS volume by reading all its bytes.

This is a small wrapper over the dd command found here.

The wrapper manages backgrounding the dd process and repeatedly sending SIGUSER1 to read its progress. The progress is then output in a nicer format that includes estimated time remaining.

Installation

There is a pre-built binary for 64 bit Linux:

 https://s3.amazonaws.com/com.codeclimate.tools/ebs-warmer-0.1.0.0-linux-x86_64 > ebs-warmer
d +x ebs-warmer
 mv ebs-warmer /usr/local/bin

Usage

e: ebs-warmer [-i|--interval SECONDS] DEVICE
rm an attached EBS volume by reading all its bytes

lable options:
,--help                Show this help text
,--interval SECONDS    Interval on which to print progress information
VICE                   Block device to read, e.g. /dev/sda1
