Hello,

I am looking at moving from Server 2012 to Unraid.  I am currently running the trial version with a 4TB WD Red parity drive and 5 WD Red 3TB drives.   I am using an OCZ 160 GB SSD for a cache drive.

All drives are XFS except cache which is btrfs.

 

I have Sonarr, Radarr, SABnzbd all installed from Linuxserver and Plex from the official docker.

 

The issue I am having is it seems the server is randomly pausing (Freezing for 10 - 30 Seconds) then functioning normally.   When this happens the indicator light for activity on my cache drive is lit solid. (All drives are in sleds and have their own activity light)

 

When this pause occurs you can see the download in SABnzbd freeze for the time of the pause (and restarts as soon as the pause is done).   Plex also freezes the playback and resumes when done.

Thinking it was maybe an issue with my cache drive I have tried another SSD and another platter drive as cache and the issue still occurs.   I have even tried setting the cache to a raid 0 with 2 ssds and while its blazing fast it still pauses.

 

This is running on an i7 computer with 12GB of ram so I don't think the issue is in that. (Windows Server also runs flawlessly on the exact hardware.)

 

I would really like to figure out the issue as I really love the software.  However if I can't get it reliable I will need to use a Windows/Snapraid solution

 

I appreciate any help that anyone can provide.

 

Thanks

You'll need to post your diagnostics after this happens
