When downloading via NZBGet the system becomes nearly unusable. The specs are:

 

- Ryzen 2700x

- 32 GB DDR4 Corsair LP

- Crosshair VII Hero

 

The array is xfs (encrypted):

- Parity: 8TB WD RED NAS

- Disk 1: 4TB Seagate

- Disk 2: 4TB Seagate

- Disk 3: 8TB WD RED NAS

 

The cache is:

- Kingston SSDNow V3 120GB (Will be replacing with 1TB Samsung 970 EVO NVME in 2 days)

 

All downloads from NZBGet go directly to the SSD cache (cache option for the share is set to "yes"). I've also attempted to pin NZBGet to the last 4 core & threads with no luck. Netdata is reporting extremely high I/O wait times as seen below:

 

 

htop is reporting extremely low CPU usage but the dashboard is reporting 100% usage:

 

 

I've got TRIM (dynamix plugin) scheduled to run hourly. A test using "DiskSpeed" reported that the cache drive should be operating normally:

 

I'm not running any VMs - just docker containers.

 

Would anyone have any suggestions where to begin to troubleshoot this issue? Please let me know if more information is required. I do believe that this hardware should be more than capable?

I am having the same issue, any resolution?

Get this working?

I got this working by buying a second SSD and putting my downloads on that.

 

TBH, it was the single best thing I did after I got unRAID setup. I am in the process of building a second box now and will definitely have two SSDs. I know it sounds insane and nagged at me (I wasn't able to figure it out) but $40 down for a 512GB was worth it. Everything is great now.

Yeah, mine is only at sata2 speeds so SSD not sure how much benefit it will do.

 

I may upgrade either way.
