Nexcloud database error
After a brand new installation of Nextcloud 17 on Turris Omnia with v5.0.3, I saw the following warning on /nextcloud/index.php/settings/admin/overview:
Some columns in the database are missing a conversion to big int. Due to the fact that changing column types on big tables could take some time they were not changed automatically. By running 'occ db:convert-filecache-bigint' those pending changes could be applied manually. This operation needs to be made while the instance is offline. For further details read the documentation page about this. mounts.storage_id mounts.root_id mounts.mount_id
Running this command cleared the issues:
sudo -u nobody php-cli /srv/www/nextcloud/occ db:convert-filecache-bigint
