I've received the complaint…
Help! My
I
drive filled up onEC2-Server-1
! Please give moar space!
However, when I remote on the the server before extending the volume, I find I cannot easily figure out which EBS volume I will need to extend.
When I run aws ec2 describe-instances --filters "Name=tag:Name,Values=EC2-Server-1"
, the relevant info found in $.Reservations.Instances.BlockDeviceMappings
shows…
DeviceName Ebs
---------- ---
/dev/sda1 @{VolumeId=vol-0123;...}
xvdf @{VolumeId=vol-0456;...}
xvdj @{VolumeId=vol-0789;...}
xvdg @{VolumeId=vol-0abc;...}
...
Following this guidance, I can see in Disk Management under Properties > General for Disk 2 (Drive Letter I
) the Location value is Bus Number 0, Target Id 6, LUN 0
. Looking this value up on the windows volume mapping table from the same page, we see the corresponding DeviceName
is xvdg
, which maps to vol-0abc
.
So… great… now I just need to click through about 5 dialogue boxes every time I need to do this (or just fuzzy match on size from the AWS Console and Windows Explorer).
Is there terminal command (or series of commands) I can execute to retrieve this mapping quickly & reliably?
I'm currently rubber ducking my way through various wmic
iterations, but… any chance this is a solved problem?

Yes, there is. PowerShell (with WMI) to the rescue:
