VPS with 8GB RAM, only 4 used

[sebastienserre]

Hello

I have upgraded my VPS from a 4GB RAM one to an 8 GB RAM.
It seems my Cloudron is blocked on 4GB... Is there something to do to allow Cloudron to use the full available RAM ?

Hello @sebastienserre

A personal desktop setup is not a server setup and can not be compared in a 1-to-1 sentiment.
Even on a personal desktop swap can be important for example, hibernation.
Without a swap partition, your desktop/notebook setup will never be able to use the hibernation feature (suspend to disk).

Cloudron does allocate for each app memory some swap memory.
This ensures, that if a system is running out of physical memory, there is some headroom for the app to continue working.

@sebastienserre Everything looks good. 4.11 GB is the additional memory as swap. What is swap?

But my VPS is 'ot a 4gb ram, it's an 8gb one.
So I should have 8gb + swap

Hello @sebastienserre
Your total memory is 7.755GiB (8GB) and 4.11 GB of SWAP memory.
What makes you think it is still only 4 GB?
If you are referring to the graph, memory is used as needed, your 8 GB of memery will not be in full use all of the time unless it is needed.

OK, so what I do not understand is why the system is using Swap evenif there's free RAM available.
On my personnal desktop (Linux Mint),I have no Swap partition for example
