Changing /dev/shm size for OpenVZ container

Adapt the container's /etc/fstab add (example: increased to 384 MByte):

Code: 
none  /run/shm  tmpfs  defaults,size=384m  0  0

Hi,

I needed to do this also, but my fstab entry is being ignored?

What exactly do you mean? Should work in containers (not only OpenVZ, which is outdated in the meantime, also in LXC). Give more details!
 
Richard, just revisiting this.

I've tried editing my fstab but it doesn't have any impact. I tried some other guides to change the LXC containers configuration but that also didn't work.

I'm trying to make it large, say 8GB or more, i am running Ubuntu LXC container on Proxmox 4.4-12

@zm:~$ df -h /dev/shm/
Filesystem Size Used Avail Use% Mounted on
tmpfs 3.9G 3.0G 922M 77% /dev/shm
@zm:~$ cat /etc/fstab
tmpfs /dev/shm tmpfs defaults,size=8g 0 0

You cannot change /dev/shm in ubuntu containers - above I mentioned /run/shm
 
If i change the size of /run/shm, and point my app to it (zoneminder), then it only uses the 4GB from /dev/shm, someone told me they are symlinked?
