UNRAID Won't Join Domain

[GingerNinja0913]

Hey, everyone! I just wanted to see if anyone could help me out here. I cannot get this working. So, I changed the UNRAID DNS server 1 to point to my server, my FQDN is LJB.Internal, and I am using the administrator account of the server as the login. However, UNRAID does not want to join the domain at all. I checked my NTP servers and tried multiple others and none of them will resolve the issues, so I don't think it's a time issue.

Here are my latest logs:

I also don't understand why it constantly says time errors when I use Google's NTP or US.Pool.NTP.

Thanks in advance!

Just wanted to share since I ran across this post yesterday when dealing with the same problem, I fixed mine by deleting the computer account on my domain controllers. I waited until it replicated and then reran the join. Joined up just fine. 

 

I wasted too much time troubleshooting, especially with a simple fix, that I wanted to make sure that someone else having the same problem may have a quicker solution.

Hi, Resurrecting an old thread here. 

 

I just noticed that I am experiencing the same/similar behavior as the OP. Some key items I noticed in my logs when I click on the Join utton (the UNRAID server was previously joined to the domain): 

 

16:23:57 Server sshd[31346]: Received signal 15; terminating.

16:24:09 Server emhttpd: shcmd (217): /etc/rc.d/rc.samba stop

....

 

Within this environment, the only AD DC left is running as a VM within UNRAID. With the DC VM started, I can go to the SMB settings page, find the UNRAID server listed as not joined and click on join (domain). At this point the above happens. Unfortunately, I think this is triggering unassigned devices to unmount a SSD which in turn causes the DC VM to go down. 

 

This may have done this previously but I haven't noticed UD dismounting drives before when clicking on join domain. 

 

Any ideas/thoughts would be welcome. Thanks!

syslog extracts are good, but your diagnostics could provide more information.

Thanks ChatNoir, however I think I might have worked out what is happening, at least in my scenario. 

 

I suspect that Unraid (v6.9.2 in this scenario), triggers a stop of services when the array is started and someone clicks on the "Join" button in the SMB Settings > Active Directory Settings section.

 

16:23:59 Server emhttpd: Stopping services...
16:23:59 Server emhttpd: shcmd (212): /etc/rc.d/rc.libvirt stop

 

To date, I have only ever used that button when the array was stopped (along with Libvirt and docker in a stopped state). In my scenario, by clicking on join, it causes unassigned devices to dismount any drives mounted in unassigned devices.

 

16:24:09 Server unassigned.devices: Unmounting All Devices...

 

My DC VM is located on a drive mounted with unassigned devices, hence the domain join does not work (Libvirt is stopped, stopping the VM) and the drive with the VM is now dismounted so it cannot start it again anyway. 

 

Prior to today, I had a second DC which was not hosted in Unraid, but now must be running into this issue since that second DC failed. Reading up in the forums, it seems like you cannot host a single DC VM in Unraid and also have Unraid use that as the DC it joins the domain with (a bit of chicken and egg I guess). 

 

For now, I am going to use a temporary DC VM until I can get the second DC back. 

 

I think the only thing I could use, to close this off, would be a confirmation that with the array started, clicking on Join under SMB settings will trigger the VM and Docker services to stop and trigger unassigned devices to dismount drives. 

 

Thanks in advance!
