Sluggish unRAID

Featured Replies

My machine is E5-2683 v3 (14C/28T) Xeon with 32Gb. On 6.3.5 was snappy but since running latest RC4 and RC6 its been super sluggish. 

 

I just tried to access my Plex docker UI and after 30s of waiting I lost the will to live. Earlier today Plex reported lost connections. Now it has reported "This page isn't working, 192.168.0.200 didn’t send any data. ERR_EMPTY_RESPONSE" on Chrome. Same on my Mylar docker, Apache and more

 

Everything is just like on slowmo... but my CPU usage never gets above 20% in the 6 cores I now allocated to unRAID and dockers (keeping 8 dedicated to VM only). This was 4 and 10 and worked fine before. 

 

I am UEFI booting (but not yet trying any Xeon multiplier tricks which was the reason I wanted UEFI booting).

 

Ah... while typing my Plex page has opened but reported  "There was an unexpected error loading the dashboard   Please visit our forums if you continue to experience problems" and my Mylar has loaded. And my Apache. And now CPU is at 80%, then 20% but still sluggish.  I wonder if the kernel is not enabling full speed and locked to speedstep lowest frquency or something...  This isn't fun. After months of happy use I am now wondering if I would not be better back to a Windows server and separate machines rather than VMs.

 

 

 

 

 

 

While it might not show anything, any answers are impossible without diagnostics

Please try normal boot and see if this is the culprit.

Sorry forgot to post them but did collect them. Will also try BIOS boot

Any chance that the unrar'ing of Max Payne is simply consuming all the available disk bandwidth and bringing the system to a crawl temporarily?  IE: what happens if you disable the docker service?

Thanks I appreciate the time taken to look at it.   Ive found some other new problems that seem to indicate some weird shit has happened on my system. I found

 

My disk 3 got Overfilled to 12Gb free (was set to 50Gb free). Was set to High Water. Had to manually move to make space. 
 

Found my Domain files which were set to Cache only had been redistributed to HDDs - so I had files in wrong places

 

My VM assignments now clashed. So I had a VM using 2 cores that were also assigned to unRAID. I had set the system to exclude 10 cores for VMs and leave 4 for unRAID. But there were overlaps.

 

So dont spend any more effort diagnosing this. I'm gonna fix all these anomalies (which I didnt have) and see whether it works now. Seems better already but Im gonna do some housekeeping

OK normal BIOS boot.  CPU load is 5-8%.  Only Apache docker and Plex docker and a Win10VM which uses 4C/8T with 4C/8T empty as 8C/16T are reserved for VMs. Basically unRAID and those 2 dockers have 6C/12T and my unRAID GUI is now OK. Will add dockers one by one and see if I can find the issue.

 

I do wonder though if something has changed in recent RCs with regard to HDD drivers?

Today after switching off what I thought MIGHT be the docker causing issues (Radarr) I still found it was taking minutes to load pages.

 

Gave up on Chrome and fired up (for first time in months) Edge and it was just there - everything working on web interface at least. My Chrome is v59 64bit and it used to work fine with unRAID. I wonder if its a Chrome memory leak? Either way, no other changes but Edge worked.

 

Some very strange stuff happening with my machine. 

Clear the browser's cache of Chrome, that usually works for me when it acts 'strange'.

Certainly helped... but now I see I have CallTraces in my logs according to FixCommonProblems (which wouldnt load at all until Chrome "fixed"!)
