LVM允许用户对硬盘资源进行动态调整。 LVM是Linux系统用于对硬盘分区进行管理的一种机制,理论性较强,其创建初衷是为了解决硬盘设备在创建分区后不易修改分区大小的缺陷。尽管对传统的硬盘分区进行强制扩容或缩容从理论上来讲是可行的,但是却可能造成数据的丢失。而LVM技术是在硬盘分区和文件系统之间添加了一个逻辑层,它...

COMMANDS The following commands implement the core LVM functionality. pvchange Change attributes of a Physical Volume. pvck Check Physical Volume metadata. pvcreate Initialize a disk or partition for use by LVM. pvdisplay Display attributes of a Physical Volume. pvmove Move Physical Extents. pvremove...
逻辑卷是建立在卷组之上的,与物理卷无直接关系,对于逻辑卷来说,每一个卷组就是一个整体,从这个整体中切出一小块空间,作为用户创建文件系统的基础,这一小块空间就称为逻辑卷,使用mkfs等工具在逻辑卷之上建立文件系统以后,即可挂载到Linux系统中的目录下使用。 使用600G空间从fastDevice创建一个名叫data 代码语言...

Configuration commands are to be run as root or by using sudo. Creating physical volumes To allow the LVM subsystem to use disk space, it must be partitioned and formatted in a special way. For this purpose, "Linux LVM" type partitions (type 8e in MBR, or 8e00 in GPT) are created ...
lvmove: This command is used to move an LVM Logical Volume from one Physical Volume to another. By understanding these LVM concepts and the associated commands, you can manage storage devices in a more flexible and scalable way on a RHEL-based system....
In this case, I added a-(dash) before the2Tsize, indicating I want that quantity of space subtracted from the existingsales-lvcapacity. The difference between the two commands is small but important. You now have the returned capacity to the VG for use in another LV. You can use the ex...
