##更改逻辑卷名称
[root@test~]# lvrename /dev/VolGroup/lv_home /dev/VolGroup/lv_u01
Renamed "lv_home" to "lv_u01" in volume group "VolGroup"
更改/etc/fstab的挂载
重新挂载mount /dev/mapper/VolGroup-lv_u01 /u01
如果是更改root、swap的目录，还需要修改/etc/grub.conf
[root@test~]# # more /etc/grub.conf
# grub.conf generated by anaconda
