59.4 Nextcloud Maintenance Mode
20200123 When performing maintenance operations on the Nextcloud server the application should be set into maintenance mode. Connect to the nextcloud server:
$ ssh nextcloud.myserver.com
Then go into maintenance mode:
$ occ maintenance:mode --on Maintenance mode enabled
Perform whatever operations are required. In this example the Security & setup warnings page on the browser under Settings, Administration, Overview for this Nextcloud instance recommended the following action:
$ occ db:convert-filecache-bigint Nextcloud is in maintenance mode - no apps have been loaded Following columns will be updated: * mounts.storage_id * mounts.root_id * mounts.mount_id This can take up to hours, depending on the number of files in your instance! Continue with the conversion (y/n)? [n] y
This was almost instantaneous for my testing.
Then come out of maintenance mode:
$ occ maintenance:mode --off Maintenance mode disabled
Alternatively, edit /var/www/nextcloud/config/config.php to set:
'maintenance' -> true,
Perform the maintenance and then edit it again:
'maintenance' -> false,
