CentOS 6.5的磁盘管理

Disk Management of CentOS 6.5

进入大数据时代,以往简单的磁盘管理功能已不能满足客户需要。能够自由组合、扩充磁盘容量,有效地利用多块磁盘上的容量,增加磁盘容错性能成为大数据存储追求的目标。以Cent OS6.5系统为例,介绍了Linux操作系统下的磁盘管理功能,包括基本磁盘管理和动态磁盘管理。其中,逻辑卷管理和构建磁盘阵列解决了磁盘分区扩容和容错的问题。

In the era of big data, the functions of simple disk management have been unable to meet the needs of users. It is the goal of large data storage to be able to combine and extend disk capacity, effectively use the capacity of multiple disks and to increase the fault-tolerance of the disk. The paper, taking CentOS 6.5 as an example, introduces disk management functions under the Linux operating system, including basic disk management and dynamic disk management,among which the logical volume management and the construction of the disk array solve the problem for expansion and fault-tolerance of disk partition.
