Works with RAID:LVM works flawlessly with the software and hardware RAID. You can set up a RAID array and use LVM to manage the volumes/partitions of the RAID array. Data Migration:LVM can migrate the data between physical volumes with ease. The LVM data migration works even if the physic...
This discussion has barely scratched the surface of how to use disks and other storage devices on Linux systems. See Chapter 4 for more information about using disks. Later in this chapter, we’ll examine how SCSI support works in the Linux kernel. 这次讨论只是浅尝辄止地介绍了如何在Linux系统...
How to work with LVM Introduction LVM (logical volume manager) is a special Linux OS subsystem that provides additional options for managing partitions on hard disks. Unlike the classical scheme, when partitions that are used for file systems are created on every disk, LVM allows for combining t...

in fixed partition, LVM creates file system in flexible logical volume. Since logical volumes are flexible in nature, we can add additional disk space in a volume which is filled up or we can shrink a volume which is merely used and has a plenty of free space. LVM works in three layers...

否则,就有可能导致数据丢失。同样,向现有系统添加新发行版时,可能需要确保您的 MBR 中拥有最新的 LILO 或 GRUB。如果您打算从 LVM 或 RAID 磁盘引导,也需要拥有比较新的 GRUB 或 LILO 版本。 LILO 和 GRUB 中使用的阶段 2 加载程序允许从几个操作系统或版本中选择其中之一。但是,LILO 和 GRUB 差别很大:只要...
