I was in situation where I was in need to enlarge EBS volume size, so I did it via AWS Console -> changing from default 8GB to 15GB.

Then I followed this tutorial: https://linuxconfig.org/how-to-resize-ext4-root-partition-live-without-umount

Next, AWS Console -> EC2 instance -> reboot.

Then, after few minutes some errors occured: 1/2 checks passed: These checks monitor your software and network configuration for this instance..

So I decided to create a snapshot of this volume and create a completely fresh EC2 instance with additional volume with this snapshot.

I tried to make this in this way: https://devopscube.com/mount-ebs-volume-ec2-instance/

But after sudo file -s /dev/xvdf I see error with information this is a root EBS volume, so I can't make it.

That was my last logs of instance after "Reboot" action:

[[0;32m OK [0m Unmounted /run/user/1000.
[[0;32m OK [0m Reached target Unmount All Filesystems.
[[0;32m OK [0m Stopped target Swap.
[[0;32m OK [0m Stopped target Local File Systems (Pre).

Any ideas guys how to restore and get files from this volume?

  • Do you have a snapshot from before you started changing your EBS volume? When you say you "see error with information", can you edit your question to include details of the error? – Tim Jul 17 '20 at 22:20
  • Nope... and that was my big mistake, I've just added last instance logs. – sarahparker_1989 Jul 18 '20 at 05:23
  • Can you please edit your question to give precise error messages regarding where you say "I see error with information this is a root EBS volume". – Tim Jul 18 '20 at 06:44
