I have 5 - 4B-4GB's and 1-8GB systems. One of the 4GB systems is experiencing an excessive shutdown (power off) time of 4.5 minutes. All the other systems take about 15-20 seconds, all my systems utilize the boot from USB. The 4GB one in question uses a 500GB SSD USB 3.0. I am using the shutdown option from the GUI. All systems are up-to-date.
Troubleshooting performed: Removed SDD and used a 32gb SD card, shut down took longer (5 minutes). I wager, that this is not directly related to the 500GB SSD. Ran Pi Diagnostics - SSD and SD card passed.
- Added troubleshooting steps:
- Swapped the SSD from the 4GB Pi to a 8GB Pi. The 4GB Pi still took about 5 minutes to shutdown with a different SSD. The 8GB Pi using the 4GB SSD shutdown in < 10 seconds.
sudo systemctl powerofffrom the command line the outcome is identical as using the GUI shutdown - 5 minutes to shutdown - no messages were displayed.
- Performing a Reboot does not take more than a few seconds, it is not affected by the problem(s) the shutdown has.
Trying to identify a process(es) that may be taking to long to perform an orderly shutdown or a process that shouldn't be running at all; but not understanding how the OS operates has its draw backs. I am not sure of next steps to try. I've searched online and the search engines are of little help.
I'd rather not rebuild the SSD as this just makes the problem go away without the learning process to add to my knowledge. Any help would be appreciated.
