For those of us with removable drive bays, should we be doing anything after unmounting a drive, before physically removing it?
-
I'm running 6.8.1 with a 3-drive raid1 cache pool. I've been getting Errors on Cache Pool messages, and many of the following in the logs:
BTRFS error (device sdf1): error writing primary super block to device 1
kernel: sd 7:0:0:0: [sdf] tag#15 UNKNOWN(0x2003) Result: hostbyte=0x04 driverbyte=0x00
kernel: sd 7:0:0:0: [sdf] tag#15 CDB: opcode=0x2a 2a 00 1d 9b af c0 00 00 58 00
The device still shows a green ball on the Main tab, but smartctl returns
Short INQUIRY response, skip product id
A mandatory SMART command failed: exiting. To continue, add one or more '-T permissive' options.I'm assuming that the drive needs replacement.
My only use of cache is VM's and Dockers, and I have disabled both services, as well as temporarily disabling the mover job.
I would like to remove the cache pool from the configuration until I can obtain a replacement.
I assume that the procedure is to stop the array and unassign all of the cache drives, and start the array. Then when the new drive arrives, reassign the 2 good drives and the replacement, and start the array. Please confirm my procedure.
I only have remote access to the server for the next few days.
Thanks

It's not the same model:
WD80EFZX-68UW8N0 - 1st gen helium filled model
WD80EFAX-68LHPN0 - 2nd gen helium filled model
WD80EFAX-68KNBN0 - newer air filled model
Most likely, that disk look fine, unless there's a firmware bug which I find very unlikely.
I just purchased two WD80's. To my surprise, what arrived were WDC_WD80EFAX-68LHPN0's. I thought all new stock was air filled. Helium is a plus for me, they run a few degrees cooler.

unRAID version (6.8.1) not supported. plugin: run failed: /bin/bash retval: 1
Being marked for deletion, and cannot reinstall on 6.8.1
Its for this kind of issue that binhex isolated preclear in a docker.

Just a general plex question ... i have set up a 'basic' plex server which is working just fine for local content only. I have been given a plexpass gift for xmas. How (can?) i integrate it into my existing server with minimal fuss?
Once the plexpass is associated with your plex account, connect to your plex server using the web interface. Logout of your plex account, then login again. You’re done. You now have all the features of plexpass. Binhex’s plexpass docker gives you access to beta releases, not additional features.

Any reason why you are not on the latest stable? Hard to troubleshoot if not on similar kernel.
Was waiting for a 6.8.1 stable that fixed the problem Settings-->VM Manager-->DIsable VM function does not work without stopping the array. If an 6.8.1-RC seems stable, and it is the only way to fix the problem, I'll probably jump early.

I'm running 6.6.7. After running preclear, I am attempting to format a new 8TB drive. I updated UD, installed UD Plus, and enabled Destructive Mode. Clicked the red X, and entered Yes to remove the partition. The log says that the partition is being removed, but it's not. The red X comes back.
fdisk -l shows that the partition still exists.
Running parted returns "parted: error while loading shared libraries: libreadline.so.8: cannot open shared object file: No such file or directory".
I tried removing UD and UD Plus, removing their plugin folders in flash/config/plugins, rebooting, and reinstalling. Same result.
Any ideas?

They changed their development plans. AES-NI is no longer a future requirement.
Mentioned here:

Another option is the Virtual Machine Wake on Lan plugin, and a wol app on your phone or tablet. I’m using the “WOL” app on an ipad.
-
For me, building with removable drive bays, then keeping my hands out of the box unless absolutely necessary, has added more to the reliability of my hardware than any other factor.
+1 for using server class hardware.

Unless you really need it, make sure UPnP is turned off on the router.

I'm recording to a local drive on the MC pc. Weekly, I am moving the recordings to unraid. They never exist in both places at the same time. After moving recordings, I need to restart the Windows Media Center Receiver Service so MC registers the change in the location of the recordings.
Keep in mind that with your method, you are asking unraid to do something that it was never designed to do - receive data on a real-time basis. The more simultaneous recordings that you do, and other things you may have running on on the server (plugins, dockers, VMs), the more difficult it will be for unraid to keep up. The forums on www.thegreenbutton.tv have several threads on user experiences recording to a NAS.
In the future, I am going to attempt to run Win7 MC as a VM on unraid. And I'll either direct recordings to a dedicated Unassigned Devices drive, or pass through a physical drive to the VM for recordings. In my house, all sh*t breaks loose if recordings are corrupted.
-
I've always been reluctant to try your method, except on my test MC server. Especially with reports of array slowness in 6.7.x. I record locally, then weekly, copy the recordings to Unraid, and remove them from local storage. At the very least, consider limiting your recordings share to one disk, and have the link reference \\server\diskx\sharename rather than \\server\sharename, bypassing the overhead of the Fuse file system.
There's no problem having MC use unc paths to previously recorded content. Its only the recording drive that needs the mklink trick.
Nothing else comes to mind about using MC with Unraid.
-
The following is from Windows 7 MC.
In MC, go to Tasks | Settings | TV | Recorder | Media Libraries | Remove folders from library. Verify that you do not have a reference to the recordings share on Unraid. If you do, delete it. Media Center should only know about your local drive, which is linked to the share. It won't show up in this list because its the recording drive). If MC knows about both, you'll show the duplicate recordings.

I use the Recycle Bin plugin for accidental deletions. Works well, but only catches deletions via SMB, not through the console or a file manager like krusader.

Just a bit of education here, please keep in mind guys Plex Pass gives you early access to features, but it also gives you lovely early access to bugs as you have all seen, if you want to minimise this happening in the future then run binhex/plex instead, you still get access to all the plex pass additional stuff with a reduced risk of stuff blowing up in your face, the option is of course yours, i know which version im running and it aint this one 🙂
@binhex, consider adding this information to the first post. It will help new users decide which docker to use.

hmm so custom bridge seems to have a limitation/bug, if you choose custom bridge then it looks like you cannot define both host and container port, so yor only option is default bridge (or host of course).
For experimentation, I'm running two Plex dockers (one LinuxServer and one Binhex), using different appdata folders. Since you can't change the port that Plex listens on (38400), I needed to assign a different IP address to one of the dockers. So the Binhex docker is running on Custom:br0, and a fixed IP address. br0 is a Linux bridge, not a Docker bridge, so port mappings are not required. Its like Host mode.
I'm still on 6.6.7, but that shouldn't matter.

I believe that within unraid you can only use vlans for dockers and vms. See if you can configure your switchport to send vlan 10 traffic as untagged, while sending the other vlans as tagged.

Is there a "Safer" way to run a SSD pool?
Make sure all shares are set to COW.
Any problem converting the system share containing the docker and libvirt images to COW?
-
I'm planning on adding a new SSD to my cache pool, and was wondering if and how Unraid users test new SSDs.
I give spinners a SMART long test, and 3 Preclear passes.
-
While testing the "Virtual Machine Wake On Lan" plugin, I discovered that I had two VMs using the same MAC address (sloppy editing of the XML's). It would be useful if Fix Common Problems could scan the docker configs and VM configs for duplicate MACs, and the docker configs for duplicate IP's.
-
If the interface is connected to a cable modem (not router) or some such device, your upstream provider's first hop is on the same link-local subnet that you are. It seems that the most secure way to run a vm firewall is with a pass-through wan nic.
-
Testing done with 6.4 RC6, with unRAID and a test client in VM's.
Even though an interface is configured for "Network Protocol = IPv4 only", an IPv6 link local address is being assigned to the interface or bridge. This happens if an IPv4 address is assigned, or the interface is configured for "IP Address Assignment=None".
The enclosed screenshots show the server Network Settings, an ipconfig, and a Windows client connected to eth1 with no IP addresses assigned. The client can ping the server, access the management GUI, and access server shares, all through the IPv6 Link Local address.
This can be a security concern if the interface is Internet facing, with the intent that the bridge will be used for the wan port of a vm firewall .
-
Sure.
Watch Gridrunner’s excellent video for background information.
QuoteI’ll only describe what is different.
You’ll need an additional usb key for the vm. Prepare it exactly as you would when installing unRAID on a physical machine. Run make_bootable.
If you will be using a stubbed out passthrough usb controller for the vm usb key, you can leave the vm key label as UNRAID. If not, change the label and modify /syslinux/syslinux.cfg. I used UNRAID-VM and changed
append initrd=/bzroot to
append unraidlabel=UNRAID-VM initrd=/bzroot
If running 6.4 RC4 in the vm, copy the modified /syslinux/syslinux.cfg to /EFI/boot/syslinux.cfg.
Ignore everything in the video about making an image of the key, defining the image file as a virtual disk in the vm template, and copying the image to the domains folder.
In the vm template, change the BIOS to OVMF.
Boot the vm, then connect to the console with novnc or another vnc client. You’ll be at the UEFI shell.
Type:
fs0:
cd EFI
cd boot
bootx64.efi
or just
fs0:\EFI\boot\bootx64.efi
You should see the normal unRAID boot menu, and you’re up and running.
So far, I haven’t found an alternative to booting unRAID from the shell each time.
Also, the unRAID OS GUI Mode boot options don’t seem to work in VNC. They would have been useful.

docker container access to system /usr/bin

Install the netdata docker and take a look at the template variables, including what you see when you press the Edit buttons. Some of the system variables are defined read-only.
