[lemon@lemon ~]$ df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/mapper/vg_lemon-lv_root
                       47G  6.3G   38G  15% /
tmpfs                1005M  284K 1004M   1% /dev/shm
/dev/sda3             485M   63M  397M  14% /boot
/dev/mapper/vg_lemon-lv_home
                      4.5G  2.3G  2.0G  54% /home

120G笔记本,60G for linux, 可是刚刚再拷贝东西到/home/lemon/某个目录下的时候提示空间不足,我才df一下,晕,/home 仅4.5G 

问各位可修改这个目录的空间大小么,原来lvm卷组自动分配空间么只要不自己分配固定物理卷区除非硬盘满了才会提示空间不足,郁闷...

使用引导光盘进去,对 / 进行缩减,然后把 home扩大 就可以了

lvm扩大,缩小,你自己先参考一下资料再操作

晕,我硬盘安装的木有光盘,一定得用光盘引导么?有没有别的方法?

貌似 LVM 支持热缩放 LVM 大小的,或者某种角度说就是为了便捷热缩放用的。

不过我只做过热扩展,没试过热缩小。

你需要复制的文件有多大?
照你的DF输出,如果/home空间确实不够用的话,可以考虑将/dev/mapper/vg_lemon-lv_root(即/)缩小,再将/dev/mapper/vg_lemon-lv_home(即/home)放大,另外不知道你的系统LVM卷组空间分配情况,如果有Free PE的话则可以直接放大/home,请使用pvdisplay和lvdisplay进行查看
