Hetzner Cloud, how to expand the volume of the main volume?

Question

Hetzner

Good afternoon.
There is a server on Hetzner Cloud cx21 (ubuntu)
It has 20GB of disk space in the database.
When buying additional space, how do I expand the main volume?
Because as there was 20 GB of space for the site, it remains so.

Answer 1

You need to understand how a new location is added: a) if as a new virtual disk, then we format it into the desired fs and mount it where we need to increase the space; b) if the existing disk increases, then we expand the physical volume, then we expand the fs.
Apparently in your case, option "a" is suitable
. condition: if lvm is used, then we add a new disk to the volume group and expand lv, and then fs.

Answer 2

With such questions, you should contact Hetzner support, in fact, you also pay money for this. Moreover, this is just Linux, and not some highly specialized product.

Answer 3

there was no way
to either expand your virtual machine to grow the root partition, or move the site to a new partition and free up space on the root

Answer 4

as an option, the main disk can be increased by expanding the virtual machine, but only through snapshot
if just rescale, then the disk size remains the same
