[*]Multiple devices driver support (RAID and LVM) <*>Logical volume manager (LVM) Support 然后重新编译内核,即可将LVM的支持添加到新内核中。 为了使用LVM,要确保在系统启动时激活LVM,幸运的是在RedHat7.0以后的版本,系统启动脚本已经具有对激活LVM的支持,在/etc/rc.d/rc.sysinit中有以下内容: ...

To grow the size of an existing logical volume, use thelvresizecommand. Use the-Lflag to specify a new size. You can also use relative sizes by adding a+size. In that case, LVM will increase the size of the logical volume by the amount specified. To automatically resize the files...
