I think a full resync then re-index will go fine. My setup is different in that I sync everything through Nextcloud and run a script that looks for changes and triggers an indexing scan in photoprism. That being said I’ve absolutely mutilated some photo prism databases (migrating servers, different folder names with the same content) and run full indexing and never ended up with duplicates. It’s very good at stacking and cleaning up the same files in the DB so long as there aren’t actual duplicates in the original storage. But again it might take 3 or more full scans to find and purge duplicates.
I am far from a photo prism expert but I can safely say the indexing algorithm is weird and takes multiple runs to finish. Logically I would expect to run it once and it would do everything in one scan but I’ve found it takes sometimes 3 to 5 full scans to update and properly catch up to major changes. It’s almost like it acknowledges big changes and documents it but waits for multiple passes before committing it. Also it does a really good job when scanning to look or duplicate images and stacking/repointing to the valid file. I would advise running the indexing another 2 or 3 times if you are confident the 31k files are actually on storage and just not showing up on the database.
Sorry, I forgot to post the scripts. I’m a meathead electrical engineer so I don’t use GIT or anything so here is the code dump. To summarize the setup’s software:
The backup script is fairly boring, just runs rsync and pushes the rsync log files back to the primary server. If it fails it sends me an email before turning the ethernet back off and going black.
#So here is my python code that runs the button press:
#!/usr/bin/env python
import RPi.GPIO as GPIO
import subprocess
import time
from multiprocessing import Process
#when this script first runs, at boot, disable ethernet
time.sleep(5) #wait 5 seconds for system to boot, then try and disable ethernet.

GPIO.setup(3, GPIO.IN, pull_up_down=GPIO.PUD_UP)

GPIO.setup(23, GPIO.IN) #pull up or down is optional, the TFT display buttons have a hardware 10k pull up. Measure low tranisitions
GPIO.setup(24, GPIO.IN)
#watches the button mounted above the USB port, in the Pi's case.
def case_button_watch():
while True:
GPIO.wait_for_edge(3, GPIO.FALLING)
#wait 100ms then check if its still low, debounce timer
time.sleep(.100)

#do something as it's a button press
print('Button is pressed!')
time.sleep(.900)
if GPIO.input(3) == GPIO.LOW:
#if the button is pressed for over 1 second its a long press. Run the backup script
print('Button long press (greater than 1 second), running an unscheduled backup')
subprocess.call(['/home/pi/backup.sh'], shell=False)
else:
#the press was greater than 100mS but less than 1000mS, just toggle the ethernet
print('Button short press (less than 1 second), toggling the ethernet')

if __name__ == '__main__':
#run three parallel processes to watch all three buttons with software debounce

#bash script that toggles the ethernet - if its on, it turns it off. if its off, it turns it on:

Does anyone see the attatched mp4 video? If not here is an imgur link.
I understand that everyone doesn’t always have a perfect experience but I’ve been using the same instance of nextcloud for over 8 years I just keep upgrading and migrating. It just works. Only issues I’ve had is when Debian withholds updating php for too long or when they finally do all the config files for php get fucked and I have to redo them all.
