Can Plesk manage disk space or extend a partition on Linux based server?

Question

Can Plesk manage disk space or extend a partition on Linux based server?

Answer

Plesk does not manage disk space on the server.

If the server is running out of disk space, try to clean the backup folder /var/lib/psa/dumps/

It is possible to add a new disk, move the contents of a huge folder – for example
/var
and mount the new disk as
/var
directory.

If the server filesystem has configured LVM, it is possible to extend partition according to the Plesk KB article: How to resize hard drive on Linux systems with LVM?
