[问题]根目录空间100%

[lambertzhang]

昨天在安装/linux-headers-2.6.24-19_2.6.24-19.36_all.deb时，出现了rux如下问题：
E: /var/cache/apt/archives/linux-headers-2.6.24-19_2.6.24-19.36_all.deb: failed in buffer_write(fd) (10, ret=-1)

A package failed to install. Trying to recover:

先查看根目录被100%used，df -h结果如下：

root@lambert-desktop:/home/lambert# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda1 2.4G 2.3G 0 100% /
varrun 252M 108K 252M 1% /var/run
udev 252M 64K 252M 1% /dev
devshm 252M 12K 252M 1% /dev/shm
/dev/sda10 12G 494M 11G 5% /home
/dev/sda8 2.8G 608M 2.1G 23% /opt
/dev/sda6 471M 11M 437M 3% /tmp
/dev/sda9 5.6G 542M 4.8G 11% /usr/local
/dev/sda7 950M 248M 654M 28% /var

然后用find / -size +50000K -print查看了根目录下大于50M的文件，仅有如下：
root@lambert-desktop:/# find / -size +50000k -print
/home/lambert/eclipse-java-ganymede-linux-gtk.tar.gz
/home/lambert/eclipse-SDK-3.4-linux-gtk.tar.gz
/home/lambert/.mozilla/firefox/0dyvtd5z.default/urlclassifier3.sqlite
/proc/kcore

/usr/local/share/scim-python/engine/PinYin/py.db
/sys/devices/pci0000:00/0000:00:0f.0/resource1
root@lambert-desktop:/#


之前也搜索过相关的帖子，以为是我的文件系统出了问题，用mount看了一下：
root@lambert-desktop:/# mount
/dev/sda1 on / type ext3 (rw,relatime,errors=remount-ro)
proc on /proc type proc (rw,noexec,nosuid,nodev)
/sys on /sys type sysfs (rw,noexec,nosuid,nodev)
varrun on /var/run type tmpfs (rw,noexec,nosuid,nodev,mode=0755)
udev on /dev type tmpfs (rw,mode=0755)
devshm on /dev/shm type tmpfs (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
/dev/sda10 on /home type ext3 (rw,relatime)
/dev/sda8 on /opt type ext3 (rw,relatime)
/dev/sda6 on /tmp type ext3 (rw,relatime)
/dev/sda9 on /usr/local type ext3 (rw,relatime)
/dev/sda7 on /var type ext3 (rw,relatime)
root@lambert-desktop:/#
发现了一个error，不过经查证，这是系统自定义的，意思是当系统挂在出现问题时，以ro形式挂载，现在我不知道该如何释放我的根目录空间了，请大虾解答，谢过了！～～～～～

总共就 2.4G,不满才怪呢...

[lambertzhang]

可以扩展吗？

[dogfox]

可以迁移?等待你迁移/成功的消息

[lambertzhang]

请问大虾们，是不是解决方案只能是扩展呢？很奇怪的是我现在连上网都不行了，我用xp下的vm虚拟的ubuntu，以前没有做任何配置，就可以在ubuntu下自动连接到无线，现在找不到无线网卡了，很奇怪，我想如果能够找到无线网卡，是不是可以用apt-get remove和apt-get clean做些什么？
