How to use ramdisk in Ubuntu and Fedora?
In Fedora, the ramdisk is disabled by default, that is, it is compiled into
the kernel, but as a module, which will be loaded into the kernel when
actually used. So, it is necessary to compile the kernel manually to select the
ramdisk as the built-in modules.
In Ubuntu, the ramdisk support is enabled by default, so the steps are
easier compared to Fedora.
Using the following commands to list the ramdisk:
| ls /dev/ram* |
The output will be like:
| /dev/ram0 /dev/ram10 /dev/ram12 /dev/ram14 /dev/ram2 /dev/ram4 /dev/ram6 /dev/ram8 |
| /dev/ram1 /dev/ram11 /dev/ram13 /dev/ram15 /dev/ram3 /dev/ram5 /dev/ram7 /dev/ram9 |
Format the ramdisk as an ext4fs:
| mkfs.ext4 /dev/ram1 |
Then mount it:
| sudo mount /dev/ram1 /mnt |
