Error establishing a database connection and Server Error 500 after 100% full disc

Hello all,
I have a huge issue with my server after filling 100% of the HDD. I was using woocommerce API to add products and didn’t notice that the disc is full. I emptied some space and now it’s 86% full but I still get Error establishing a database connection when I visit the site and Server Error (500) when i try to login Cyberpanel. I have restarted the server but it’s still not working. Any advice?
Thank you in advance!

Have you try run update script and reboot server?
