使用AWS将单个Amazon卷从gp2迁移到gp3

Question

如何使用AWS将现有卷从gp2修改为gp3？

我想试试剧本，

#! /bin/bash

region='us-east-1'

# Find all gp2 volumes within the given region
volume_ids=$(/usr/bin/aws ec2 describe-volumes --region "${region}" --filters Name=volume-type,Values=gp2 | jq -r '.Volumes[].VolumeId')

# Iterate all gp2 volumes and change its type to gp3
for volume_id in ${volume_ids};do
    result=$(/usr/bin/aws ec2 modify-volume --region "${region}" --volume-type=gp3 --volume-id "${volume_id}" | jq '.VolumeModification.ModificationState' | sed 's/"//g')
    if [ $? -eq 0 ] && [ "${result}" == "modifying" ];then
        echo "OK: volume ${volume_id} changed to state 'modifying'"
    else
        echo "ERROR: couldn't change volume ${volume_id} type to gp3!"
    fi
done

要验证脚本是否像我们所期望的那样工作，但是只有一台机器，而不是所有使用gp2的机器？我需要对脚本做哪些更改？

如果要在速度模式下进行测试，可以在包含第一个元素的条件之后在循环中添加一个中断:)

比如：

# Iterate all gp2 volumes and change its type to gp3
for volume_id in ${volume_ids};do
    result=$(/usr/bin/aws ec2 modify-volume --region "${region}" --volume-type=gp3 --volume-id "${volume_id}" | jq '.VolumeModification.ModificationState' | sed 's/"//g')
    if [ $? -eq 0 ] && [ "${result}" == "modifying" ];then
        echo "OK: volume ${volume_id} changed to state 'modifying'"
        break  <==== 
    else
        echo "ERROR: couldn't change volume ${volume_id} type to gp3!"
    fi
done

但我建议您在第一次请求时更加具体，通过addind标记筛选器(Name)获取特定卷，以便只获得一个用于测试的卷EBS

对于来自aws控制台或cli的ebs卷类型修改。https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/requesting-ebs-volume-modifications.html

或者，使用AWS系统管理器>自动化>执行。https://docs.aws.amazon.com/systems-manager-automation-runbooks/latest/userguide/automation-aws-modify-ebs-type.html
