I am having a problem trying to determine what my drives are doing sometimes. My NAS is near my bed so if the drives are spinning I can hear them. It's not annoying or anything, but sometimes I can hear the drives spinning when I would think they shouldn't be. Here is what I mean by that.
As a preface, I'm not very knowledgeable with FreeNAS, I know just enough to follow tutorials and youtube videos to get everything setup how I want.
I have 3 jails running. One for a Mumur server (Mumble), one for Transmission, and one for Plex. The Mumble server is used just as a backup and really, no one is on it. I don't leave Transmission torrents going at night, so that shouldn't be the cause. It also happens when I'm not watching anything on Plex.
Now I know the NAS is not limited to those 3 jails, but outside of a snapshot task, I don't know what it could be doing and I'm wondering Is there a way to tell what is writing/reading from the drives?
I have included a screenshot of the Disks screen where you can see writing is happening to the drive but my goal is to find out what.
I have snapshots set to run weekly on Wednesdays for the jails but the activity I've described above happens outside of that window.
