Stuck on 'Array Stopping •Sync filesystems...'

[DerToosoon]

On disk2 of my array i have two directorys. If i try to list them with 'ls', the shell get stuck.

But, if i create a new directory on disk2, i can list it like normal.

 

So, i wanted to stop the array and reboot. [windowsuser, new to linux, try unraid since a week]

But now the Array won't stop also, it hangs on  'Array Stopping •Sync filesystems...'.

 

i did some research and found processes in state D, which means "uninterruptible sleep (usually IO)" which, i think they depend to the problem.

 

USER         PID       %CPU %MEM VSZ       RSS     TTY STAT START     TIME   COMMAND

dertoos+    10183   0.0      0.2     56016    18104  ?      D      Dec02    0:09   /usr/sbin/smbd -D

root           28644  0.0      0.0     3088     1768   ?      D      07:51      0:00   /bin/ls -F -b -T 0 --color=auto

root           7634    0.0      0.0     3088     1812   ?      D       08:42     0:00   /bin/ls -F -b -T 0 --color=auto

 

(the last two processes seem to be the directory listings, that stucks the shell)
 

Google says, i maybe have named "symlinks" which have circular dependencies.
 

What can i do ? My unraid ist stuck in state "stopping" and i can't access the files in two directorys on disk 2.

If you were in the shell and the current directory happens to be /mnt/user/... (or simply /mnt/user), then the system won't be able to stop the array properly.  There's a plugin called StopShell which will forcibly kill any processes like that which will impede a shutdown

[DerToosoon]

This "Stop shell" plugin sounds great, but it looks like i can't install plugins anymore. 
The installation hangs, as seen in the picture. 

 

Can i do the stop manually ?

If its stuck, then yeah your options become limited.  And another thing which will also cause the system to fail on Sync Filesystems is if you happen to be running a PreClear on a drive...

[DerToosoon]

no, i wasnt running preclear lately. maybe i did when i was setting up the server, but i think thats not what u asked for 🤔

 

What can be the reason that ssh (or web terminal) will get stuck when ls'ing this specific directorys ?

I switched the computer off. Now i have to do parity check. The directorys seem to be listable again.

Thanks for ur help.

I have been having the same issue for a while, the array takes forever to shutdown.  I also am having really slow data transfer speeds, moving 400mb files from my download share to my media share @ 5.47mbps.

I am attaching a diagnostic that I ran the other day right after doing a hard reboot.

Any suggestions are appreciated.

Hi 

Sorry, I did get this fixed, but I can't remember how, I think I had a HD issue at the time.
