Mount does not limit the size of drive












0















I set a ramdisk via



sudo mount ramfs -t ramfs /media/typicalramdisk/ -o size=1M 


Then I put files inside it. They exceeded 1 MB and I still could place files in this drive.



I tried 1m, 900k and a few other options. None of them limited the drive.



Does mount limit the size of the mounted disk in any way?

  • The limit to ramfs is your physical RAM itself. See: wiki.debian.org/ramfs In other words, you cannot limit ramfs.

You should create the ramdisk using tmpfs, not ramfs.



ramfs is an older implementation and lacks size checking (see here).



So your command will become :




sudo mount tmpfs -t tmpfs /media/typicalramdisk/ -o size=1M

  • tmpfs is great. But it might use swap instead of pure ram.
