mkdir /mnt/ramdisk mount -t tmpfs -o rw,size=240G tmpfs /mnt/ramdisk
NOTE: This mounts a ramdisk with 240GB under the path /mnt/ramdisk.
- -t tmpfs:
- tmpfs only uses memory when you it contains files.
- When it is empty, it will take almost no space in RAM.
- An alternative to tmpfs is to use ramfs.
- tmpfs can use swap as well, whereas ramfs devices are memory only.
