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

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

g.
