Summary of the issue you are facing:
I uploaded around ~6Tb of data to my nextcloud /data//files directory and it wont show up in nextcloud. When doing research on the issue people are saying to run ‘occ files:scan’ but nextcloud 31 doesn’t have that anymore. I’m unsure of what to do to get all my files to show up.
Steps to replicate it (hint: details matter!):
- Install Nextcloud 31
- Run occ files:scan --all
