Package amazon-efs-utils-1.29.1-1.amzn2.noarch already installed and latest version
Nothing to do

Installation of amazon-efs-utils seems to be successful as shown above.

But when I try to run the tool, I get this error:

$ sudo amazon-efs-utils
sudo: amazon-efs-utils: command not found

1. Is it possible that the URL from where amazon-efs-utils gets downloaded is blocked and hence it did not really get downloaded?

2. I ran yum with --verbose option to see if it would print a trace of which URL it tries to download the tool from. But it did not! Any idea how I can find which URL amazon-efs-utils would be downloaded from so that I can try whitelisting that URL on my server and try again?

I am using Amazon Linux2 EC2 btw.

Answer 1

Ask rpm if the package is installed.

$ rpm -qa|grep amazon-efs-utils

If it is, check its contents.

$ rpm -ql amazon-efs-utils

Observe the package contents files. Also, understand that amazon-efs-utils adds some binaries prefixed by mount. Here is the output in an ec2 instance.

$ rpm -ql amazon-efs-utils.noarch
/etc/amazon/efs/efs-utils.conf
/etc/amazon/efs/efs-utils.crt
/sbin/mount.efs
/usr/bin/amazon-efs-mount-watchdog
/usr/lib/systemd/system/amazon-efs-mount-watchdog.service
/usr/share/man/man8/mount.efs.8.gz
/var/log/amazon
/var/log/amazon/efs

You can check if the efs-utils is installed via following commands

mount.efs --version

And you can check the command line tool detail via

man mount.efs
