Preview generation:

in config.php

enable_previews → true / false

  preview providers -> check for certain type

storage location:

data/appdata_instanceid/preview

previewgenerator app

generates previews to preview storage location

  using config settings
  occ preview:cleanup
  occ preview:pre-generate -> only new files!
  occ preview:generate-all -vvv --workers=n username
  files:scan-app-data

Metadata storage:

pre-v33:

oc_filecache table

from v33:

oc_previews table

Fix:

# config.php : 'enable_previews' => false,
# occ preview:cleanup
# DELETE FROM oc_filecache WHERE path LIKE 'appdata_<instanceid>/preview/%';
# occ files:scan-app-data
# config.php : 'enable_previews' => false,

Regenerate previews if lost or broken:

# disable ALL nc cron jobs
# run fix 
# log in with nc user: e.g. w_nc (don't sudo, not working)
# nc_directory # php occ preview:generate-all -vvv --workers=n username
# re-activate cron-jobs
