Unmounting Issue 4.5.6

In the middle of playing a mp4 file from a share tonight, the picture just froze. I attempted to resolve this issue by rebooting the device and attempting to access the file again. That failed to resolve the issue.

 

So, I attempted to stop the array so that I could reboot the server and it just sat there for 30 mins., doing nothing. I found a number of posts with similar issues and was able to find that the file was still showing as being accessed from the telnet console. So, I killed the PID that was being used to access the file. That made all the other "Unmounting" statuses on the other disks go away, but the "Unmounting" status remained for disk2. So, in another post I found by Joe L. he suggested a user could have avoided a similar unmounting issue by running:

killall emhttp  and then running:

emhttp &

 

I tried this angle and the issue still remains. I'm not sure what the error means that's being thrown in the syslog, but, here's the meat and potatoes of it(see Log below):

Oct 14 22:15:15 UNRAID emhttp: Retry unmounting disk share(s)...

Oct 14 22:15:20 UNRAID emhttp: shcmd (23): umount /mnt/disk2 >/dev/null 2>&1

Oct 14 22:15:20 UNRAID emhttp: _shcmd: shcmd (23): exit status: 1

 

So, what does the ">/dev/null 2>&1" mean? Why is unRAID so angry at me now? What can I do to make it happy again?

 

Thanks For Your Time.
