after installing that plugin and downloading the LibreElect 6.8.2 release i rebooted.

First of all, thanks for the solution A couple of questions:

 

1. What is LibreElect and why is that needed to get the webcam to work?

2. How do you download LibreElect? Is it through Community Apps?

Mhh to be honest not yet due to the correct WebGui information (all disks showing spun down) and the fact that all dockers running on the cache drive. 
 

But if you think it can cause the problem I’ll try it today evening and report tomorrow. 
Thank you and have a nice day

Just as a part of process of elimination. It's not clear to me that the server will go to sleep with an active docker. That seems dangerous for the server to go to sleep if a docker in the middle of writing to disk.

[[6.8.3] - Not understandable disk activity]

As an experiment, have you tried disabling your Dockers and see if it will go to sleep properly?

[Parity Disk Error - Disk Toast?]

A full disk write might fix it for now, but once a disk has issues it's more likely to have more in the near future.

Agreed. This is more for academic curiosity. Once the preclear finishes, I plan to physically destroy the platters

SMART test failed so that drive needs to be replaced.

Already swapped in a spare. Running parity rebuild now.

 

Also running preclear on "P2" just to see what happens.

[Parity Disk Error - Disk Toast?]

Well, I stopped the parity check just before Parity Disk 2 hit 800k ERRORS. Looks like it is toast Going to swap it out.

[Solved: Parity Swap nightmares]

I'm having a hard time following what you are doing. Screenshots would help us follow your process. Are you running dual parity? Sounded like you did the parity swap and that went fine, but then you decided not to go through with it? 

[Parity Disk Error - Disk Toast?]

Well, not looking good... Parity check slowed to a crawl at 93.4%, with 12 days estimated left to go at 233 KB/s. Parity Disk 2 is now up to 526k ERRORS.

[Parity Disk Error - Disk Toast?]

My monthly parity check just ran, and came up with some errors for my Parity Disk 2:

 

 

Self-test history:

 

SMART report:

smart_report.txt

 

A bit of a background. I had this disk (we'll call it "P2" for short) previously in QNAP 4-Bay NAS. The QNAP flagged P2 as bad, so I replaced it with a new disk. I then ran P2 through chkdsk /r twice, and it didn't find any errors. So when I built the Unraid box, I put all 5 disks into service. So P2 already was kind of suspect.

 

I guess what I'm asking is, is P2 toast? Should I just replace it?

[Dynamix - V6 Plugins]

Question about Dynamix System Autofan:
 

1. What do the temperature threshold refer to? I don't see an option to associate the temperature readings to specific temp sensors, so I assume it's just the average of disk temperatures?
2. What if I want to associate my CPU fan controller (pwm1) to the CPU temperature, and not the disk temperature?
3. Are the settings separate for each PWM controller?
4. I see only "Fan control function" as "Enabled' or "Disabled". Does it mean it's all or nothing? What if I only want to enable System Autofan for some of my fans (namely my case fans, and not my CPU and HBA fans, especially if the reference temperature is always the disks)?

Any ideas how to fix?

 

 

Make sure the Shinobi docker is running, then open a console for the docker (click on the Shinobi icon, then choose "Console"), then run the following:

[[PLUGIN] Disk Location]

9 minutes ago, olehj said:

Heh, does it really matter though?  It mainly uses the scheme from Unraid itself, just that I don't see Unraid actually uses "green-blink" as a blinking green LED 😛 Not having any plan at the moment to change that though.. unless the majority start requesting it.

 

I try to avoid any more configurations and options than it currently has to keep it somewhat simpler.

Just thought I'd ask It would be nice for Disk Location to be consistent with how Unraid displays spun-down disks

[[PLUGIN] Disk Location]

Great plugin, thanks! Question: for disks that are spun-down, is there a setting to make the status lights just permanently grey like on the Main screen? The flashing green/grey light makes it much less glanceable. I have to wait a few seconds to see if they are green full time or if I just glanced at it while it was green during a blink.

I had to reinstall today and it seems there's a few problems.

 

1. install scripts are not creating db (few posts above describe this)
2. I'm not able to add this user:

 

When i click add account, populate all the information and save, it doesn't do anything at all. No errors in UI or logs, no indication of saving.  Refreshing the doesn't show the user I attempted to create. 

Noticed the author updated a day ago and also know that gitlab upgraded today.   <maybe that's it>

Try doing it with the JavaScript Console open and see if you see any errors. It's generally under the Developer menu for most browsers.

[External USB Disk SMART report?]

6 hours ago, Benson said:

I don't think so, because I have two different 5 bays USB enclosure, both can't passthrough SMART info. in first ( I haven't try set to SAT-auto-12 or SAT-auto-16 in that time, unraid just show you may try "-d sat" ).

 

One of them after flash another firmware, then Unraid can read SMART info. in default perfectly , PID and VID also change. Non-multi bay USB bridge should be another story, most could passthrough SMART info.

Ah I was thinking more about single drives. Totally anecdotal, but I have a WD My Passport Ultra 1TB on hand (which is on Smartmontools' supported list) and Unraid is able to read its SMART info.

Thanks for the sanity check -- I was only looking at the backplane. It does indeed have a USB 2 header on the MB. I'll connect it and give it a whirl.

 

Thanks!

 

I'm using this head cable for my boot drive:

 

https://www.amazon.com/gp/product/B015F6QXKO/

 

Most motherboard USB2 headers are 10 pin, so this plugs right in. Not to say that 5 pin or 4 pin cables (like StarTech one that most people here use) won't work, but the advantage of this cable is that it gives me 2 ports and some length so I can route it to somewhere more convenient.

Yes, but not all controller/bridge.

Smartmontools has a list of supported USB hard drives (link in my original post). Can I assume that Unraid's supported devices list is similar?

[Parity drive speed question]

42 minutes ago, Jason Harris said:

Hi all -

I am looking to build a new UnRAID Plex server soon.  The purpose of it is to host a Plex media server.  Easy enough.

 

The storage disks will be 5400 RPM.

 

I am wondering if I should spring for my parity drives to be a bit faster in the event of a parity rebuild.  Would it help with the speed of the rebuild effort, or does it just not matter?

The write speed will be dictated by the slowest disks that are accessed during writes. And since parity disk(s) are always accessed during writes, the general recommendation is to use the fastest disks you have in the array as the parity disk(s).

[External USB Disk SMART report?]

I know that many external USB Disk controllers are able to pass on the necessary ATA commands to make SMART work. Smartmontools has some good info on this:

 

https://www.smartmontools.org/wiki/USB

https://www.smartmontools.org/wiki/Supported_USB-Devices

 

So theoretically, for supported controllers at least, you should be able to get the SMART data.

 

Does anyone know if Unraid will show SMART reports for external USB Disk?

[[SOLVED] Unraid Cache drive issue]

Try installing the "Dynamix Active Streams" Community App and see if there's an open SMB or AFP stream somewhere that you were not aware of.

I got this figured out and am able to use the MariaDB inside the container to make this work. No need to run a dedicated MariaDB docker instance.

 

First, make sure the shinobipro docker container is running. Log into the console of the container, either by using the unraid feature or by this command:

docker exec -ti shinobipro sh

Next, create the database and tables...

 

mysql
source sql/framework.sql;
source sql/user.sql;
exit

Now restart the container and it will work.

Fantastic post. Had this exact problem. This worked!

[Cache drive and Mover question]

2 hours ago, tmoran000 said:

I am trying to fully understand the cache drive and how necessary it is. I am primarily running a plex server and NAS for achieving.. 

here is my question..

 

1) The files I move onto the server that get put onto the cache drive before the mover moves them... will they be simulated as in their final resting place? I.E. if I move a file to my movies folder although it goes to cache. untill its moved by the mover will I still be able to find this file in the movies folder. 

 

2)  If that file is in use while it is on the cache drive and the mover tries to move that file.. will it fail to move? Will it kill the plex stream of someone watching it or if its a Doc. will it error out the doc thats opened or will it move without interrupting the current access of the file.

 

Thank you

 

 

1. Yes, the path to your file is the same from your client computer. Unraid knows where the file really is behind the scenes, and will serve it from wherever it is, cache or array.

 

2. Mover will not move a file if it's in use. It'll just skip it.

[Cache - Last Recently Used]

On 5/7/2020 at 4:22 AM, Marek said:

Greetings!

I'd like to ask if it's possible to implement in near future that I can work exclusively off of SSD and files are backed up let's say once every hour. But if the SSD gets filled, last recently used files will be removed and new files will take it's place.
I'm working with 3D simulations and this is one of several occasions where I can take advantage of even several RAID 0 nvme SSDs. 

Sometimes one frame has more than 2GB which gives you almost 50GB/s of data for 24fps scene. Of course such a speed is another topic of limitations but it's just simply impossible to read from HDD's ( not only the read speed is limiting, but also Random access speed).

 

I currently have 12TB of HDD (2x4TB + 1x4TB parity) and regular SSD, planing to upgrade to 2TB nvme and 40Gbps networking.

Is there any solution to this? I really like unRAID, would be nice if I can use it not only for my personal (travel photos, movies), but also professional use.

 

Thanks in advance

Marek

Some point in the future? Probably. Near-future? Doesn't sound likely. Check out this Q&A with LimeTech's CEO from Aug 2019:

Take a look at this:

 

 

Not certain if it will work for you, since I have a different thermal/fan chip (IT8688), but worth a try.

Hi all, System Temp doesn't seem to have drivers for my motherboard's temperature sensors (Gigabyte Z390 M Gaming - ITE IT8688E). Here's the "sensor-detect" output:

 

Here's the "sensors" output:

 

I set ACPI Temp 2 as MB Temp, but I have no idea if that's correct. I in fact have no idea what those 2 ACPI tempeatures are. The motherboard has 6 thermal sensors and 4 fan headers:

 

Furthermore, under "Array Fan Speed" in Dynamix System Temp, I'm not able to select anything at all.

 

Any help would be appreciated.

I found a workaround:

 

Specifically, this part at the end:

Quote

 

Fan Speed Sensors and PWM Controllers: See warning below!

You can already see your CPU temp (Tctl) using the k10temp driver with Dynamix System Temperature. If you want to see Fan Speeds on your dashboard, or use the Dynamix Auto Fan Control plugin, we can force the it87 driver to load for the it8628 on this board. To force this we need to set another boot flag, "acpi_enforce_resources=lax". Add this the same way as above, after "video=efifb:off". That line in your syslinux.cfg should now read "append initrd=/bzroot video=efifb:off acpi_enforce_resources=lax".

 

Next, add the following line to /boot/config/go

 

Quote

modprobe it87 force_id=0x8628

 

The it87 driver will now load on boot and your fan speeds will be displayed on the Unraid dashboard, and the fan controllers will be available in Dynamix Auto Fan Control.

 

Warning: Setting acpi_enforce_resources to lax is considered risky for reasons explained here.  

 

Of course I didn't need the "video=efifb:off" part, so I just added "acpi_enforce_resources=lax" to my /boot/syslinux/syslinux.cfg, then "modprobe it87 force_id=0x8628" to my /boot/config/go. A little risky (see link above), but otherwise seems to be working well so far. Will monitor it for any instability. Just want to share my findings in case someone else finds this post later.
