[Lxc-users] PostgreSQL - "sh: cannot create /dev/null: Permission denied" - LXC Issue?

[Jäkel, Guido]

Dear Patrick,

As I understand /dev/null isn't writable in your container. That's definitely a wrong configuration.

Please check, that there is a real device node for  /dev/null  (and others) in your container and you have it (and others) in the lxc device access control list (lxc.cgroup.devices.allow = c 1:3 rw)

Note that -- depending on the linux flavor in your LXC container -- you might have to populate /dev by your own, because it's not reasonable to run udev or something like this inside a container.

Greetings

Guido
