I've got Error 500: closing file '/var/tmp/pve-reserverd-ports.tmp.14162' failed when trying to console to qm. It says also No space left on device. I can see no space left on /dev/dm-0 , what should I do ?

Hi erase some files like the journals or the apt cache.

root@pve:~# df -kh | grep dev/dm-0
