sudo file -s /dev/xvdf command failed

[minnoc]

sudo file -s /dev/xvdf failed after attaching volume to the EC2 instance. To fix it i named it /dev/xvdf when i attached the volume

named what ?
I'm really not sure what you are saying ...
/dev/xvdf is a device ID ... you aren't naming anything.

AWS Certified Solutions Architect - Associate (SAA-C02)
Lesson is
[DEMO] EBS, Snapshots and Instance Store Volumes - PART1

yes i'm referring to the device. In the lesson it's listed as /dev/sdf, to make it so the command sudo file -s /dev/xvdf didn't fail, i changed the name in the EC2 console to /dev/xvdf when attaching the EBSTestVolume to the EC2 instance

I'll have a look because /dev/sdf should be mapped as /dev/xvdf in linux
Thats how it is on my video .. and it worked ok.
The device ID changes depending on linux distro, but amazon linux should use /dev/xvdf for /dev/sdf set in console
