I'm looking for some help around this task:

a) cd /
b) run #tar -cvf users.tar users
c) #umount -l /users
d) #mv /users /OLDusers
e) comment in fstab #/dev/redhat/users
lv    /users  ext4    defaults,nodev  1       2

So basically, I need to archive a directory, unmount it and then comment it from the /etc/fstab file.

Commenting the fstab, I think can be done via augeas. Could you please help me with the archiving section.

Thanks DarylW. We only use Puppet for Configuration Management and the current ask is to automate a list of steps we perform after a host is provisioned.

I'm basically looking for a method in puppet which can help me archive a directory. I don't want to use "exec" to run these commands for various reasons. Hence the ask.

Thanks for your response though.

If is is on a fresh provision, why do you need to archive them? Either way, you are basically limited to a one time script that would do the steps you need in an exec (with appropriate onlyif/creates params)

This isn't a task that you would do with puppet. Puppet is about describing the existing state of the system that you want, not a series of steps to perform some task across the systems.

There are a few tools that can help with performing 'tasks' across your infrastructure. fabric, Ansible, MCollective(made eaiser with the current plugins from, etc.

With those tools, you can define a playbook/runbook/set of instructions that you will execute on all of the machines (the archiving task), and then you can use puppet to ensure the fstab changes are set to the configuration that you require.
