与控制台和EC2不同的AWS fdisk卷名

Question

我正在检查ec2-instance (centos-7)内的映射卷。我已经将两个500 GB的卷附加到一个ec2实例，但我找不到哪个卷映射了哪个磁盘名称。

磁盘名称显示为/dev/nvme3n1 and /dev/nvme5n1，但亚马逊网络服务控制台显示为/dev/sde /dev/sdd

fdisk -l和aws ec2 describe-volumes .. device_names是不同的。有没有办法找出哪个卷映射到哪个设备名称？

fdisk -l

[root@ip-192-168-66-22 deploy]# fdisk -l



Disk /dev/nvme3n1: 536.9 GB, 536870912000 bytes, 1048576000 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes

Disk /dev/nvme5n1: 536.9 GB, 536870912000 bytes, 1048576000 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes

AWS客户端结果

aws ec2 describe-volumes --filters Name=attachment.instance-id,Values=$(curl -s http://169.254.169.254/latest/meta-data/instance-id)

Answer 1

您可以将其中一个卷增加1 GB，以区分这两个卷
