Available space on hosting environment

I’m having the exact same issue. How do i resolve it?

I’d first check the use of my storage on my disks:

df -h

I have unlimited storage on my server plan so that is not the issue?

But physically, there is no unlimited disk. So there is a system function that can ask for the available space. On hosted environment, this is sometimes not the real available space (because the provider does not give you a dedicated partition) and instead some other value (based on your quota, something else or something invalid). Some managed to find a workaround for their hosting provider that it worked in their environment (back then, it was with OVH).
