How to increase size of /dev/shm?

[James Board]

I'm running FC 14 and the /dev/shm is no longer as big as it used to be (under an older FC).
How can I increase the size of the /dev/shm? I tried the following

mount -o remount,size=6G /dev/shm

Which seemed to work, but then the system hung when I tried to use the extra space and I had to reboot. What's the correct way to increase the size of the /dev/shm partition?

Thanks

Did you find the answer, James? https://wiki.archlinux.org/index.php//dev/shm

Alter /etc/fstab's entry for /dev/shm and apply settings with mount -a, or reboot:

none /dev/shm tmpfs defaults,size=6G,noexec,nodev,nosuid 0 0

That isn't working for me. I think the problem is because I'm on a machine with 12 gbytes of RAM, but I'm running 32-bit Fedora Core 14. /proc/meminfo says the machine has 3 gbytes of memory. This seemed to work fine in Fedora Core 13, but doesn't in Fedora Core 14. I created a new thread titled 'FC14, 32-bit Physical Memory' because the problem might be different than merely increasing the RAM disk size. If you have any ideas, let me know.

Thanks.

You will need to either upgrade to a 64 bit OS (that would be my first choice) or run the 32 bit PAE kernel.
