So, i started to get warning and errors on my 3 1tb drives, one was cashe drive, the other 2 were just part of the array.

I removed them and resetup the array with just the 4 much newer 5tb drives and 1 2tb.

 

I am now getting all sorts of performance issues. Plex is freezing all the time, loading the pages just take extra long to load.

 

I am thinking about starting everything fresh but i want to keep my current array so i dont loose data or the parity.

Is there a way to do this? Or any other suggestions?

 

Thanks

Matt

 Can you please grab your diagnostics zip file and post it please.

 

- either grab the file via the GUI by going to tools>diagnostics and download the zip file.

- type diagnostics from the command line and get the zip file it saves from the unRAID flash drive.

 

I'd like to have a look @ your smart reports and check disk health.

Here is the log file.

 

What i have done so far is removed all dockers except Plex, and their appdata folders.

(Plex is the only thing I care that works to keep the wife and kids happy)

I just accidentally hit the reset button plugging in a keyboard, so it is currently doing a Parity-check.

 

Thanks

Disks seem fine. So I am going to have to dig to try and help your diagnose.

 

The big difference between your before state and your after state (following the replacement of the disks) is that you're now (according to a line in the Sy's log) no longer using a dedicated cache drive. Why the change?

 

Also, what are the disk settings (is it spanning all disks or on the root of one?) of your appdata share? Are you using Plex to transcode?

 

1 of the 3 1tb was not giving errors or warnings, however is was just as old(7 to 8yrs) and was bought at the same time and that was the cash drive.

So since the other 1tb drives were giving errors. I figured i would play it safe and remove it (plex worked before I added that drive too). When I have extra cash again I plan to get a new 7200RPM 1TB or 2TB drive to replace it.

 

From what I can tell its set to the default settings.

Yes I am useing Plex to Transcode. (it was crashing with just 1 device tying to transcode and watch)

When I went to to remove the appdata it was all on disk 1.

 

With all the indexing plex does with the metadata I was thinking about moving it to disk 4 the 2tb so it did not interfere with videos it is trying to play.

 

I think that seems like a reasonable test.

 

Given your issues are performance and not general operation I feel it is plausible that the reading (video source) and read / writing (transcoding) at the same time coupled with any other general use would be more than enough I/O activity to cause some Plex performance issue(s).

 

Try and seperate the two as you suggest (video source and plex operation) onto different disks and try.

 

Post back your results - which will hopefully let us close the loop on this issue and have you operating smoothly! ?

Will do, thanks for the feedback...it was just racking my brain because I went from an older Athlon II x4 to a dual Opteron (32cores) setup.

The Athlon II x4 system worked but was getting older and having stability issues with ram and system crashes.

 

This has a 10gb SFP+ NIC going to a switch with 2port 10gb uplink and 48port 1gbe...so overall bandwidth should never be an issue.

 

It could be the cache drive, but I didn't want to leave a drive in the system that could possibly fail at any time...but i worked before the cache drive too...

letting plex rebuild its metadata index and then ill test some of the movies I have had issues with.

And now looking at the transcoding location it was the same disk as all the media, so moving that to disk4 might solve the issue.

 

I'll let you know if these changes solved the issue.

 

P.S. I just realized, I might have a hybrid 500gb hard drive somewhere could use as my cache. I might try to find the laptop i have that in.

Good luck! ?

So I found a 120gb SSD if forgot i had, Set it up as Cache.

 

The videos were still kinda choppy while indexing the metadata but once that finished, it seems to be playing correctly...

And the metadata indexing completed much faster than it has in the past.

 

Now just have to reconfigure all my other dockers and the Win7 VM for our eyefi card

 

Thanks for your help
