    • postfix causes high iowait - do I need postfix?


      On my system (OMV & debian on a HP Gen8 Microserver) I had a lot of postfix and bounce processes running and over time they slowed down my system a lot by causing a lot of iowait. I stopped the postfix service and the problem was gone. see below.

      So my questions are:

      Does OMV need postfix? Or can i safely disable / uninstall postfix? I don not want an SMTP Server running on my NAS if I don't have to.
      For notifications i use an external SMTP-Server Server.
      did anyone else experience similar problems or was that just me?
      Is there a problem with the installation image? Why is postfix installed and running in the first place?

      Thanks and keep up the good work!

      OMV needs postfix to submit notifications, Postfix is running as satellite. You can not uninstall it because it is hard tied via package dependency with the OMV package.

      I must not fear.
      Fear is the mind-killer.
      Fear is the little-death that brings total obliteration.
      I will face my fear.
      I will permit it to pass over me and through me.
      And when it has gone past I will turn the inner eye to see its path.
      Where the fear has gone there will be nothing.
      Only I will remain.
