    Since V5 I am struggling with the GUI stalling when i stop the array from the main menu. The messages either go into a loop around freeing the releasing the shares, as just now again, the webgui becomes unresponsive and gives a "This webpage is not available - ERR_NAME_NOT_RESOLVED". I have searched the forums and came accross the Kill open files plugin which doesn't always help and have installed the extended powerdown script which sometimes takes the array down, but the big button is still often the only resolve. This leaves the array with an unclean shutdown which I really want to avoid whenever possible. In all cases the GUI becomes unresponsive and cannot be used anymore.
     
    I am writing here because I suspect that the only real resolution is the change the "stop array" function in unRAID to check for any stop down hindrances and either
     
    
  1. 
     
  2. inform the user what the problem is, stop the process and make the GUI responsive again
     
  3. attempt the resolution of the conflict ie. by offering to kill those processes individually
     
  4. just issue a warning that other processes are preventing stopping the array and proceed after a confirmation
     

   

  I must say that this is by far the biggest annoyance i have with unRAID at the moment and hope that you can have stab at it during one of the upcoming releases.

   

  Thanks, tazman

I used to have this issue much more often than lately (I really don't see it often at all, and if I do it is waiting for a VM to exit), however the root of my cause was a hard drive that was on its way out.

That specific disk would always be the one that would hold this up.

Doing some investigating using old instructions from V5 or 4.7 days, the umount command would always list that particular drive as stuck, all others were unmounted correctly.

 

Anyhow thought this may help for investigating, as I've rebooted plenty through all the beta's, and no longer have this issue pop-up.

Tazman, I'm not sure that's a problem any more.  I'd really like to see you upgrade to UnRAID v6, add the current Powerdown plugin, and test it.

 

Your 3 suggestions are nice, an interactive shutdown, and have (to some extent) been requested before.  But I haven't seen any interest lately, because those problems seemed to have gone away.  There are still rare cases of the webGui becoming non-responsive though, but not because of array stopping or system shutdown.

 

Upgrade and tell us if it still happens.

I have a similar problem. Stopping my array works correctly zero percent of the time now that I've got all of my settings/software configured on the unRAID machine. It worked well before installing VMs/Dockers, but something in one of those processes causes my system to get stuck in a loop as well. It doesn't give me any option to end the process and I haven't been able to figure out which process it is through trial and error.

 

The message across the bottom of the screen when I try to stop the array (or shutdown because that also requires stopping the array) is "Unmounting disks... retry unmounting disk shares" This just scrolls forever and ever across the screen. If I leave it for an hour, nothing changes.

doesn't happen often but when it does I find clicking on the drive under the MAIN tab to stop them helps

If the array won't stop it's usually because something is using one of the disks... try running

lsof | grep /mnt/

on the terminal when it stalls and it will probably become pretty obvious what's holding it up.
