Sqlite to mysql on cyberpanel hosting

HEllo, i just istalled nextcloud using CyberPanel. the warning im getting is
“SQLite is currently being used as the backend database. For larger installations we recommend that you switch to a different database backend. This is particularly recommended when using the desktop client for file synchronisation. To migrate to another database use the command line tool: “occ db:convert-type””

i dint know where is my root folder in cyberpanel, how do i fix this?

Ask cyberpanel. Probably best to go through your hosting provider if they are how you pay hosting for.

how do i mount sdb1?
