I'm new to unRAID and trying to sort out what is happening with my server. Performance is otherwise great but when I tried copying a large number of TV shows while Cache = Yes was enabled it brought my system to its knees. All my CPU cores started going to 100% and Plex froze, but the GUI of unRAID seemed fine and I was able to get the machine to shutdown and things were fine. Determined that it was due to cache setup, so I turned off cache (cache on didn't really improve copy performance anyway) and things have seemed basically fine. My next experience was with copying over a very large VM image (1tb) from a Windows Server 2019 machine to unRAID. At some point the copy freezes, the Windows machine can't even open the shares anymore. And like before with the other issue my CPU cores all start pegging out at 100%. Still the unRAID gui is fine, but right now I'm waiting on a clean reboot and its refusing to reboot cleanly. I was able to get Plex to stop and can navigate all around the OS just fine, just can't do a clean shutdown.
My system is a repurposed HP DL380 G8 with dual 3.0ghz Xeons (10 cores each) with 400gb of RAM. I have five WD RED Pro 14tb drives, with two 512gb SSD for cache. System includes a Nvidia P2000 for Plex, and for now I only run Plex on this system.
I am very much a noob with unRAID, but fairly competent IT guy overall and comfortable with digging into things. Any thoughts or recommendations on where to look would be greatly appreciated.
