You can’t access files because they are locked and you find such errors in your logfile:
{"reqId":"0DfsdgdhdfhdfhdfD8J","remoteAddr":"xx.xx.xx.xx","app":"webdav","message":"Exception: {\"Message\":\"HTTP\\\/1.1 423 \\\"path\\\/file.extension\\\" is locked\",\"Exception\":\"OCA\\\\DAV\\\\Connector\\\\Sabre\\\\Exception\\\\FileLocked\",\"Code\":0,\"Trace\":\"#0
Manually disable locking state:
- put Nextcloud in maintenance mode: edit
config/config.phpand change this line:'maintenance' => true, - Empty table
oc_file_locks: Use tools such as phpmyadmin or connect directly to your database and run (the default table prefix isoc_, this prefix can be different or even empty):DELETE FROM oc_file_locks WHERE 1 - disable maintenance mode (undo first step).
- Make sure your cron-jobs run properly (you admin page tells you when cron ran the last time): https://docs.nextcloud.org/server/13/admin_manual/configuration_server/background_jobs_configuration.html
Permanent solution (if it happens regularly)
- on your own server: Use redis for this feature. It is faster and so far no problems have been reported. You can follow the instructions for memory-caching in the docs: https://docs.nextcloud.org/server/13/admin_manual/configuration_server/caching_configuration.html#id4
- Shared hosting (others who can’t install redis): You can disable the file locking, edit your configuration file
config/config.php:'filelocking.enabled' => false,
However, disabling is not a good solution. You can run into problems when several processes try to write to a file (especially online editors in the web-interface). In single-user and single-client environments, it’s probably less of a problem.
