调整环境使用的 Amazon EBS 卷大小

为您要调整大小的亚马逊 EBS 卷打开与亚马逊 EC2 实例关联的环境。

在环境的 AWS Cloud9 IDE 中，创建一个包含以下内容的文件，然后使用扩展名保存该文件.sh（例如，resize.sh）。

#!/bin/bash

# Specify the desired volume size in GiB as a command line argument. If not specified, default to 20 GiB.
SIZE=${1:-20}

# Get the ID of the environment host Amazon EC2 instance.
TOKEN=$(curl -s -X PUT "http://169.254.169.254/latest/api/token" -H "X-aws-ec2-metadata-token-ttl-seconds: 60")
INSTANCEID=$(curl -s -H "X-aws-ec2-metadata-token: $TOKEN" -v http://169.254.169.254/latest/meta-data/instance-id 2> /dev/null)
REGION=$(curl -s -H "X-aws-ec2-metadata-token: $TOKEN" -v http://169.254.169.254/latest/meta-data/placement/region 2> /dev/null)

# Get the ID of the Amazon EBS volume associated with the instance.
VOLUMEID=$(aws ec2 describe-instances \
  --instance-id $INSTANCEID \
  --query "Reservations[0].Instances[0].BlockDeviceMappings[0].Ebs.VolumeId" \
  --output text \
  --region $REGION)

# Resize the EBS volume.
aws ec2 modify-volume --volume-id $VOLUMEID --size $SIZE

# Wait for the resize to finish.
while [ \
  "$(aws ec2 describe-volumes-modifications \
    --volume-id $VOLUMEID \
    --filters Name=modification-state,Values="optimizing","completed" \
    --query "length(VolumesModifications)"\
    --output text)" != "1" ]; do
sleep 1
done

# Check if we're on an NVMe filesystem
if [[ -e "/dev/xvda" && $(readlink -f /dev/xvda) = "/dev/xvda" ]]
then
# Rewrite the partition table so that the partition takes up all the space that it can.
  sudo growpart /dev/xvda 1
# Expand the size of the file system.
# Check if we're on AL2 or AL2023
  STR=$(cat /etc/os-release)
  SUBAL2="VERSION_ID=\"2\""
  SUBAL2023="VERSION_ID=\"2023\""
  if [[ "$STR" == *"$SUBAL2"* || "$STR" == *"$SUBAL2023"* ]]
  then
    sudo xfs_growfs -d /
  else
    sudo resize2fs /dev/xvda1
  fi

else
# Rewrite the partition table so that the partition takes up all the space that it can.
  sudo growpart /dev/nvme0n1 1

# Expand the size of the file system.
# Check if we're on AL2 or AL2023
  STR=$(cat /etc/os-release)
  SUBAL2="VERSION_ID=\"2\""
  SUBAL2023="VERSION_ID=\"2023\""
  if [[ "$STR" == *"$SUBAL2"* || "$STR" == *"$SUBAL2023"* ]]
  then
    sudo xfs_growfs -d /
  else
    sudo resize2fs /dev/nvme0n1p1
  fi
fi

从 IDE 中的终端会话中，切换到包含 resize.sh 文件的目录。然后，运行以下任一命令，同时将 20 替换为要将 Amazon EBS 卷调整至的期望大小（以 GiB 为单位）：
