我正在使用以下Terraform模板
resource "aws_instance" "ec2" {
ami = "${var.ami_id}"
instance_type = "${var.flavor}"
key_name = "${var.key_name}"
availability_zone = "${var.availability_zone}"
security_groups= ["${var.security_group}"]
tags = {Name = "${var.instance_name}"}
}
resource "aws_volume_attachment" "ebs_volume" {
device_name = "/dev/sdg"
volume_id = "vol-006d716dad719545c"
instance_id = "${aws_instance.ec2.id}"
}
在aws中启动实例并将卷附加到该实例。
执行此操作时,我看到实例已创建,并且卷也已附加到实例。
ubuntu@ip-172-31-10-43:~$ lsblk

xvdg 202:96 0 20G 0 disk
但是当我尝试挂载该卷时,我收到了这个奇怪的错误
ubuntu@ip-172-31-10-43:~$ sudo mkdir -p /goutham
ubuntu@ip-172-31-10-43:~$ sudo mount /dev/xvdg /goutha,
mount: /goutha,: mount point does not exist.
ubuntu@ip-172-31-10-43:~$ sudo mount /dev/xvdg /goutham
mount: /goutham: wrong fs type, bad option, bad superblock on /dev/xvdg, missing codepage or helper program, or other error.
任何人都可以帮我解决我在练习中犯的错误。
谢谢。

我认为我错过了在该卷中创建文件系统的步骤,因为我试图附加的卷是一个空卷
所以这帮助了我
$ sudo mkfs -t xfs /dev/xvdg
和
sudo mkdir -p /goutham
sudo mount /dev/xvdg /goutham
谢谢

您可以使用用户数据和terraform脚本在连接的磁盘上建立文件系统。
https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/user-data.html
https://www.terraform.io/docs/providers/aws/r/instance.html#user_data
#!/bin/bash
while ! ls /dev/xvdg > /dev/null
do
sleep 5
done
if [ `file -s /dev/xvdg | cut -d ' ' -f 2` = 'data' ]
then
mkfs.xfs /dev/xvdg
fi
data "template_file" "mkfs" {
template = "${file("${path.module}/templates/mkfs.sh")}"
}
resource "aws_instance" "ec2" {
...
user_data = "${data.template_file.mkfs}"
...
}
它将在创建ec2实例时运行,并等待直到安装磁盘为止。之后,它将创建文件系统。
