When I have to reboot my unRAID server I can never seem to get everything unmounted.  After a while I just give up and issue a reboot command from the bash shell.  I have even installed the Open Files plugin and shut down everything that was open, which is a long and painful process.  I see in another thread something about having mounts on your cache drive as being an issue.

 

I do have this entry in my mounts

/dev/sdb1 on /mnt/cache type btrfs (rw,noatime,nodiratime)

 

But I am not sure where that comes from.  Is that the issue?  If so then how do I resolve it?  If not then how do I figure out what the issue is.

 

If you can, telnet / ssh in to the server and type in

diagnostics

 

Versions of unRaid prior to 6.3.0 do not have as robust a powerdown procedure and this can happen unfortunately.  One immediate thing that pops into my head is that it is quite possible under a certain circumstance for the docker.img file to refuse to unmount.  You can fix that via

umount /var/lib/docker

Thanks - I think I did see some docker images that were still mounted.

 

What should the shutdown procedure be?  Should I actually stop all dockers and all VMs before rebooting?  What is the best way to do that - one by one or can I just disable docker from the Settings-Docker page?

If you're stuck at unmounting, then its too late to attempt to stop them manually (and you really never need to do that anyways)

 

Hopefully you've got the powerdown plugin installed and can try

powerdown -r

 

if not, try the umount and see if it works

I don't have the powerdown plugin installed.  It down't appear to be in CA and the Powerdown thread starts with this:

 

Powerdown is deprecated.  It will not install in unRAID 6.2 because it is not necessary and was not fully tested for 6.2.

Not entirely true, as the built-in with 6.2 was not as good as the add-on.  But under 6.3 the built-in is better than the add-on.  Either way, if the umount doesn't work, you're stuck and have to restart with the button.  Upgrade the system as soon as feasible...

I will upgrade as soon as I hear more reports from others in the SageTV unRAID community that there aren't any issues with upgrading.
