After I built a Ramdisk, I can not write it? Could you help me? # dd if=/dev/zero of=/dev/ram0 bs=1k count=4096 4096 0 records in 4096 0 records out # mke2fs /dev/ram0 4096 mke2fs 1.35 (28-Feb-2004) Filesystem label= OS type: Linux Block size=1024 (log=0) Fragment size=1024 (log=0) 1024 inodes, 4096 blocks 204 blocks (4.98%) reserved for the super user First data block=1 1 block group 8192 blocks per group, 8192 fragments per group 1024 inodes per group Writing inode tables: done Writing superblocks and filesystem accounting information: done This filesystem will be automatically checked every 36 mounts or 180 days, whichever comes first. Use tune2fs -c or -i to override. # mkdir /mnt/rootfs # mount /dev/ram0 /mnt/rootfs/ # cd /mnt/rootfs/ # mkdir bin mkdir: cannot create directory `bin': Input/output error #

以上我是在RedHat FC2英文版上的結果.我嘗試在RedHat 9英文版上卻沒問題!!!
