docker.img and libvirt.img not unmounted on shutdown causing errors

[dlandon]

unRAID OS Version: 6.2RC5

 

Description: docker.img and libvirt.img not unmounted on shutdown.

 

How to reproduce: Boot in safe mode and then shutdown.

 

Expected results: docker.img and libvirt.img unmounted.

 

Actual results: docker.img and libvirt.img stay mounted and cause console errors.

 

Other information:

console errors:
Unmounting local file systems:
umount:  /mnt/cache: target is busy
                (In some cases useful info about processes that
                 use the device is found by lsof( or fuser(1).)
umount: /mnt: target is busy
                (In some cases useful info about processes that
                 use the device is found by lsof( or fuser(1).)

I stand corrected.  I'm not sure what is causing the problem, but the docker.img and libvirt.img mounts don't seem to be causing the issue.

 

LT,

 

I have made a few changes to the rc.6 script (attached) that I would like you to take a look at.  I have incorporated a few ideas from the powerdown script:

• Save diagnostics just before starting shutdown procedure.
  
• Save syslog to /boot/logs/ instead of /boot/ to consolidate the log and diagnostics.
  
• Added explicit unmount of docker.img and libvirt.img.
  

 

If these changes are incorporated into the stock rc.6 script, then I can deprecate the powerdown plugin.  The powerdown plugin was a good idea back in the v5 days, but is no longer necessary and I am uncomfortable with a plugin taking over the unRAID shutdown process.  I will not be able to commit much time in the future to support and maintenance of the powerdown plugin.
