Hello, my RHEL6 works as expected (RAM 3GB, size=50% is the default):
tmpfs /dev/shm tmpfs defaults 0 0 tmpfs 1,5G 26M 1,5G 2% /dev/shm tmpfs /dev/shm tmpfs defaults,size=66% 0 0 tmpfs 2,0G 26M 1,9G 2% /dev/shm tmpfs /dev/shm tmpfs defaults,size=33% 0 0 tmpfs 984M 26M 959M 3% /dev/shm Also with the size=Xg notation.
