Question

我似乎无法弄清楚如何使用Amazon's instructions将EBS卷安装到Ubuntu EC2实例。有人可以帮助我吗？

~$ lsblk
NAME    MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
xvda    202:0    0  16G  0 disk 
└─xvda1 202:1    0  16G  0 part /

~$ df -h
Filesystem      Size  Used Avail Use% Mounted on
udev            492M   12K  492M   1% /dev
tmpfs           100M  340K   99M   1% /run
/dev/xvda1       16G  7.2G  7.8G  48% /
none            4.0K     0  4.0K   0% /sys/fs/cgroup
none            5.0M     0  5.0M   0% /run/lock
none            497M     0  497M   0% /run/shm
none            100M     0  100M   0% /run/user

~$ sudo file -s /dev/xvda
/dev/xvda: x86 boot sector

~$ sudo file -s /dev/xvda1
/dev/xvda1: Linux rev 1.0 ext4 filesystem data, UUID=da85f42e-5e55-40d1-95da-dea139db0d7f, volume name "cloudimg-rootfs" (needs journal recovery) (extents) (large files) (huge files)

~$ sudo mkfs -t ext4 /dev/xvda
mke2fs 1.42.9 (4-Feb-2014)
/dev/xvda is apparently in use by the system; will not make a filesystem here!

~$ sudo mkdir /data

~$ sudo mount /dev/xvda /data
mount: /dev/xvda already mounted or /data busy

Answer 1

您似乎有一个磁盘xvda，其中一个分区xvda1。分区/dev/xvda1已安装在/。由于您只有一个磁盘，其中一个分区是作为根卷安装的，因此此时您无法执行任何其他操作。您是否尝试向EC2实例添加第二个EBS卷？如果是这样，您需要先将其附加到实例，然后查找它以显示在lsblk输出中。

Answer 2

这是一个适用于 Amazon Linux 2 的脚本，您可以为 Ubuntu 重新创建，只需在使用 yum 评论原始数据时尝试：

#!/bin/bash
sudo yum -y update
sudo yum -y upgrade

# Format and mount an attached volume
DEVICE=/dev/$(lsblk -rno NAME | awk 'FNR == 3 {print}')
MOUNT_POINT=/data/
mkdir $MOUNT_POINT
yum -y install xfsprogs
mkfs -t xfs $DEVICE
mount $DEVICE $MOUNT_POINT

# Automatically mount an attached volume after reboot / For the current task it's not obligatory
cp /etc/fstab /etc/fstab.orig
UUID=$(blkid | grep $DEVICE | awk -F '\"' '{print $2}')
echo -e "UUID=$UUID     $MOUNT_POINT      xfs    defaults,nofail   0   2" >> /etc/fstab
umount /data
mount -a

# Change user for data operations / Non mandatory
chown -R ec2-user:ec2-user $MOUNT_POINT
