[Fab-user] mkfs doesn't work using fabric

[Khaled Diab]

Hi,

I am writing a python script that creating an amazon volume and attach it to an instance.

To do so, I need to create a file system using mkfs command.

So, I wrote this code:

with settings(host_string=instance.public_dns_name, user = "my_user", key_filename="my_pem", warn_only=True):

run('mkfs.ext4 /dev/xvdh')

run('mount -t ext4 /dev/xvdh /work')

It returns:

Could not stat /dev/xvdh --- No such file or directory

The device apparently does not exist; did you specify it correctly?

I tries multiple options:

- using sudo rather than run

- using pty=False and/or shell=False in the run command

I SSHed to the VM and executed these commands, and it works fine! but didn't working using fabric.

Any help is appreciated :)

Regards,

Khaled
