紧急求助，NAND刷机后法了一半容量

select326

刚到手的CB2，刷成lubuntu，http://dl.cubieboard.org/softwar ... -12.10-v1.05.img.gz
然后查看空间大小：
root@cubieboard2:~# df -h
Filesystem      Size  Used Avail Use% Mounted on
/dev/nandd      2.0G  1.5G  431M  78% /

none            100M   12K  100M   1% /run/user
root@cubieboard2:~#

这个表示不理解。

使用FDISK -l 查看分区有错误 ：

如何解决这些问题呢？？请大神帮解决下

matson

别紧张。系统只用了2GB，后面的2GB留给用户了。只需要mkfs.ext4 /dev/nande，然后mount起来用就好了

cubieplayer

听说livesuit最大支持2g

fleamboy

剩余的空间自行格式化后挂载使用。

yuruyi

nand还是尽量少用的好，调试用 sd u盘 硬盘。有满意系统刷进nand，最好再设置成只读。

flash不太靠谱，坏块多时，不是玩硬件的，想自己换芯片会比较困难。

你确定？我干了直接导致启动失败，导致我折腾了那么久的服务全挂掉了，只能推倒重来，这是我的记录，血的教训啊：
遇到的问题：
如果将dev/nande格式化为EXT4分区，开机就会出现hotplug问题，估计是cubieboard上的分区是采用sanxi-tools的nand-pard来分的，估计它的MBR（硬盘分区表）是比较特殊的，所以如果采用fdisk和格式化命令，将会导致MBR改变，然后Magic Number也改变了，于是内核启动时就会报错，也有可能是/etc/nande中有一些配置信息，内核启动时会读取，格式化之后读取不了就会崩溃
崩溃时的启动信息:

用PHONIXSUIT 1.1刷ct-lubuntu-desktop-nand-20131023.img进NAND后，第一次启动正常，接上USB键盘都登录进去了，再接上鼠标，键盘鼠标都不能用了，关机重启就一直:

  [hotplug]: try to kill cpu:1 failed!

反复重启。

插入DSD（linaro-server-ct-card0-hdmi&vga-v1.0.img）卡，可以正常启动。
