I was able to set up the VM manager so my router is providing a DHCP lease for my linux mint VM. However, I'm not able to configure my Docker settings as the guide suggests. Bonienl suggests you set up a VLAN network for Docker then says that your router will not know that this network exists. Then he says to choose a IP range that is out of the range of your Docker settings. I set it up as he did but in his example he is setting his IP address assignments in Docker network setting to automatic. But he is using the IP of the netowrk mentioned at the beginning of the write up. This is contradicting. When I try to open Plex for example I does not find it. Is having segregated VLANs really the only way to get docker containers to work on unRAID?

So I set up the networks per the guide. I went to start VM service and got an error that the libvert service failed to start. I figured I'd try to reboot. When I went to reboot it would not let me stop the array. I then clicked shut down (which I assume that stops the array before it shuts down) It then hung and became unresponsive. After reboot it now says unclean shutdown detected. And started a parity check. OMG. I just had one 3 days ago. Here are a couple screenshots from my KVM console when it shut down: Do I have to let this finish? This is where it hung:

Thanks for the info @Hoopster. Probably a dumb question (and I'm about to read through the thread again) but do I set up the VLAN in unRAID? Or on my router? I, like you will be using one interface / ethernet port on my motherboard.

I think I traced it to some Docker Containers. I'm not able to use Plex or Pihole without a crash in 3 days. I'd really love to get this solved. I've realized that I can run the following Docker containers without error: - DuckDNS - mariaDB - Swag - Nextcloud If I run Pihole or Plex I get a call trace or kernel panic within 3 days. Does this have something to do with br0? This happened last night during an appdata backup and may have stopped the backup. Can anyone translate these errors to human readable? tower-diagnostics-20210204-1128.zip

When you reboot the Wireguard gets switched to Inactive.

My goal is the set up a remote backup server at a friend's house on a Raspberry Pi and connect to it via Wireguard. I have Wireguard working in unRAID which I use with the Android and windows clients but I'd like to set up a rasPi as a remote peer where I can access the local network at the remote location from my local network. To do this would I add a new Tunnel in unRAID Wireguard settings, then create a config file and share that with the RasPi? Or would I just share the keys with the RasPi? Would LAN to LAN work for this config? Or do I create the config in the rasPi and share that with unRAID? Has anyone set this up? It seems like it could be a very useful, inexpensive way to have a remote / off-site backup.

I ended up using the wrong command when I shut down that actually initiated a 'reset'. Which is as bad as hard shutdown. I should have read more at the time. Fortunately I didn't seem to have any corruption afterwards. So I setup a remote syslog server to capture what happens before the next crash.

I was able to SSH into unraid. When you SSH in (using putty for example) do you get an option to enter a username or password? If you can SSH in to unraid you can use these commands to save the syslog to the flash before you shut down / reboot. When you shut down the logs will be lost: tail -f /var/log/syslog > /boot/syslog.txt or cp /var/log/syslog /boot/syslog.txt I also set up a syslog server on another PC using these instructions to keep a copy of what is going on if it happens again (so far it hasn't).

After Preclearing an Easystore 8TB still in it's USB enclosure I noticed the log being spammed by a repetitive message. I believe this started after I clicked the red X to "stop preclear." Note I have to click that X every time even after I'm alerted that pre-clear is finished. Here is the message. It added about 1Mb to my syslog. 2021-01-16T23:00:03-05:00 Tower preclear_disk_375347564C4C5743[7 /usr/local/emhttp/plugins/preclear.disk/script/preclear_disk.sh: line 478: /tmp/.preclear/sdg/dd_output_complete: No such file or directory 2021-01-16T23:00:03-05:00 Tower preclear_disk_375347564C4C5743[7 /usr/local/emhttp/plugins/preclear.disk/script/preclear_disk.sh: line 475: /tmp/.preclear/sdg/dd_output_complete: No such file or directory 2021-01-16T23:00:03-05:00 Tower preclear_disk_375347564C4C5743[7 /usr/local/emhttp/plugins/preclear.disk/script/preclear_disk.sh: line 475: [: -gt: unary operator expected

How did you determine it was the controller card? I had something similar happen a while back. Never did solve it.

Thanks. No, I had not started the array with the single cache drive. Your instructions worked great. Here is what I just did with the array stopped (using Edge browser): - Disabled VMs in VM Manager (Docker service was already disabled before last shutdown) - Set cache drive 1 to 'no device' using dropdown menu in Main tab (it then appeared in Unassigned Devices) - Checked 'Yes' for "Start will remove the missing cache disk and then bring the array on-line." - Clicked Start - Array didn't start because it's now asking for Passphrase (it didn't ask before) - Entered passphrase and clicked Start - Stopped the array - Reassigned both cache drives in proper order - This time I don't see the "All existing data on this device will be OVERWRITTEN" message. There are blue squares next to each cache drive. - Started array (both cache drives are mounted properly, no errors) - Started Docker service I tested Plex and Nextcloud and all is working well. Thanks for the advice.

@JorgeB mind giving me a hand with this one?

After updating BIOS the 2nd Cache drive was unassigned. When I try to assign it I get the message "All existing data on this device will be OVERWRITTEN when array is Started". I've tried Chrome, Firefox, disabling add blockers, booting in safe GUI mode and still get the same warning. Any idea why this happened? Should I just add it back and let it be Overwritten?

Anyone have any thought on this? I hate to have to do an unclean shutdown again. Should I contact Limetech directly?

Good morning, bumping this back up.

Tried to login in tonight via GUI and got "500 Internal Server Error nginx". No GUI access but Plex and Pinhole etc are still reachable. I saved the log via "cp /var/log/syslog /boot/syslog.txt". Can i post this in entirety or does it need to be sterilized? I copy and pasted this diagnostics into a Notepad ++ .txt file via SSH. The error here looks like it's trying to connect to my phone. (Phone's IP address) 500 Internal Server Error nginx

Maybe try a different phone? Or another remote client?

When I set mine up I forwarded a port in my router to the wireguard port. I set "Local server uses NAT:" to No and followed this troubleshooting tip: ( In the WireGuard config, set "Use NAT" to No In your router, add a static route that lets your network access the WireGuard "Local tunnel network pool" through the IP address of your Unraid system. For instance, for the default pool of 10.253.0.0/24 you should add this static route: Network: 10.253.0.0/24 (aka 10.253.0.0 with subnet 255.255.255.0) Gateway: <IP address of your Unraid system> On the Docker settings page, set "Host access to custom networks" to "Enabled". see this: https://forums.unraid.net/topic/84229-dynamix-wireguard-vpn/page/8/?tab=comments#comment-808801 ) This is the only way I could get it to work. Maybe it was my router specifically causing the issue. I'm also using Remote Access to Lan which works as you are hoping. And if you make any changes to configurations on the server or wireguard settings then you have to delete the peer from your client (android phone) and set up again in the client by scanning the QR code again.

Anyone know what Plex folders can be excluded in CA Backup / Restore application? I heard that you don't need to back up the entire Plex appdata directory. It takes quite a while to do a backup now and I suspect that the Plex files are responsible.

I ran the Scrub on the Cache drive. These instructions are a little outdated when using 6.9.0-rc2. I assume now you just click "Scrub" and that's it. I don't see this option on the Cache 2 drive so I assume when scrubbing Cahce it does both? The "Check" button is greyed out and says "Check is only available when array is Started in Maintenance mode" which is in conflict with the Wiki instructions for BTRFS. Also, do I need to run the Balance? I've not done this before.

@JorgeB is there a way to check for file corruption before I do a backup of all my appdata etc?

Right. So I set up the rsyslog server on another server (Ubunt in ESXi) and it's currently mirroring the log. And a thank you to @Frank1940 for the help too. If anyone has additional thoughts as to why it would crash please let me know.

Thanks Jorge. When it crashes does it risk the data on the disks? Or does it gracefully shut them down? Is there something I can do to make sure the disks are stopped properly when I reboot? I get the option to "Power off - Orderly Shutdown" with my motherboard BMS

Thanks. I'll add that there was one movie stream running from plex at the time and I think it crashed right as I opened a 2nd plex stream for Live TV tower-diagnostics-20210107-1111.zip

I noticed my server was not responding. I went in via IPMI and saw this so I rebooted. The GUI is up and I'm logged in. This is freaking me out. I rebooted and when I started the array I got this message, But the NVME Cache drive seemed to mount ok. Any Idea what caused this? Really appreciate some help. Should my next step be a MemTest? tower-syslog-20210107-0522.zip
