Get-SPTimerJob cmdlet Incorrectly lists SharePoint timer jobs?

Question

I'm trying to modify a specific timer job "Disk quota warning" for one of my SharePoint 2010 web applications via powershell. But I can't find the job that I want.

When I go into central admin -> monitoring -> review job definitions I find the web application that I want, and there is exactly one job with the name "Disk quota warning" along with about 15 other jobs for that application. This is the desired behavior.

The problem arises when I try to do it via powershell

PS > Get-SPTimerJob -webapplication "Web application name"

It returns about 20 jobs that all have the name "job-diskquota-warning".

My question is two fold,

1. Why is it displaying 20 disk quota jobs when I only have one job with that name?
2. Where are all of the other jobs for that web application?

Answer 1

Try to identify properly the timer job by using the -Identity command arg for Get-SPTimerJob

Get-SPTimerJob -WebApplication "ApplicationPoolName" -Identity "job-diskquota-warning"
