本文介绍了如何在RedHat7.5系统中进行硬盘扩展分区的操作，包括查看分区情况、创建扩展分区、建立逻辑分区、保存退出并重启生效、创建物理卷、卷组扩容、逻辑卷扩容以及文件系统扩容的详细步骤。

1.查看fdisk -l 分区情况：

[root@localhost ~]# fdisk -l

Disk /dev/sda: 1000.1 GB, 1000123400192 bytes, 1953366016 sectors

Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
