what is a ramdisk
A ramdisk lets you directly store files in physical memory as if it was on your hard drive.
How to set up a size of a ramdisk ?
sudo mkfs -t ext3 -q /dev/ram1 65536sudo mkdir -p /ramdisksudo mount /dev/ram1 /ramdisk -o defaults,rw
change the number "65536" for a larger or smaller ramdisk, alter /dev/ram1 to another RAM device if you are creating multiple ramdisks
Is bad the following realization of a ramdisk ?$ sudo mkdir /media/ramdisk$ sudo mount -t ramfs -o size=64m ramfs /media/ram
Is it permanent?
I played with the ram disk on my Mac in Snow Leopard's terminal, but there is an icon for a ram disk on the desktop that makes it easier. Where on the Ubuntu menu in Karmic Koala can I find the ram disk that this creates? And can I save files directly from Open Office into the ram disk if I follow Panayara's codesudo mkfs -t ext3 -q /dev/ram1 65536sudo mkdir -p /ramdisksudo mount /dev/ram1 /ramdisk -o defaults,rw I assume that I have to reinstall the ram disk each time I reboot--though comment on Ubuntu forums implies that Ubuntu has a ram disk in the directory dev/shm How do I mount that in Ubuntu so I can save files in it directly from Open Office or from one of the USB drives I have plugged in?
