ramdisk

[nopri]

hello ,

i created my ramdisk like this :

dd if=/dev/zero of=/dev/ram0 bs=1k count=4096
mke2fs /dev/ram0
mount /dev/ram0 /mnt/ramdisk

and i got ramdisk on /mnt/ramdisk, BUT
i couldnot change the size of ramdisk, when i specified count=8192, i still got the same result. When changed count to 16384, it still got the same as i specified count=4096

Did i make something wrong ?

please help me.
