⚠️ This issue respects the following points: ⚠️

  • This is not a troubleshooting question, general support matter, or webserver/proxy problem, but likely a bug (if unsure, ask the Community Help Forum).

Bug description

I am using nextcloud helm chart 9.4.1 . Upgraded to latest version from 9.2.*
Integrity check keep failing, in particular a nextcloud.log file keep spawning in /var/www/html and /var/www/html/ocs

I try deleting this files, but they keep spawining and the integrity check keeps failing.

Steps to reproduce

  1. Upgrade helm from 9.2.* to 9.4.1
  2. Run an integrity check php occ integrity:check-core
  3. Remove the 2 .log files
  4. Wait a little bit
  5. Run the integrity check

Expected behavior

I expect the integrity check to not fail for 2 log files or the log files to be created in the correct directory

    @stefangweichinger

    I see similar issues with files like: nextcloud/app/tmp/sfi_file_sequence_oc65lc0lmz8d/*

    I remove, rescan .. warning is gone, files are recreated, integrity check fails again
