Hi all:
I found if i build ramdisk more than 16M, i'll got error at using
mke2fs command.
dd if=/dev/zero of=ramdisk bs=1024k count=20
/sbin/mke2fs -F m0 ramdisk
mke2fs 1.36 (05-Feb-2005)
mke2fs: bad blocks count - ramdisk
why ?
I used FC3 & eldk 3.1.1.
Best Regard,
Rober Hsu

try: /sbin/mke2fs -F -m0 ramdisk

I think you're missunderstanding me.
"/sbin/mke2fs -F m0 ramdisk" means:
create ext2 filesystem on file 'm0' of size 'ramdisk'
"/sbin/mke2fs -F -m0 ramdisk" means:
create ext2 filesystem on file 'ramdisk' with 0% reserved
It looks like your missing a dash (-) for the 'm' option
