Hello,

Earlier today I've tried to update my OpenProject installation to the latest version, unfortunately I ended up with not enough space on / and I think this is a bug.. let me show you the output of the console:

So as you see I have enough space in / file system. 
Maybe it is good to mention that I run this in a LXC container which runs on Proxmox hypervisor if that matters.
I also ensure that my Inode limit is not reached:

Can you guide me how to resolve this issue?
Thanks in advance.
