1 目录简介问题解决方案简介本文描述如何增加大小磁盘在运行一 UCS Performance Manager 的基础虚拟机 (UCSPM) VMware ESXi 主机的问题有时, 当 UCSPM 的根分区变得全双工时, 系统不正常运行一个原因是日志文件由应用程序创建变得太大解决方案在您开始前, 您必须首先关闭 UCSMPM 虚拟机然后请连接对与安全壳 SSH 的 ESXi 主机 CLI 并且寻找在数据存储器的 vmdk 文件 1. 为了对一个新的指定的长度扩大在当前虚拟机磁盘文件的空间, 请输入 vmkfstools at 命令 ESXi 主机 /vmfs/volumes/datastore/ucspm11.cisco.lab # vmkfstools --extendvirtualdisk 200G ucspm11.cisco.lab.vmdk Grow: 100% done. 2. 用这些命令检查当前文件系统状态 : [root@localhost ~]# df -h Filesystem Size Used Avail Use% Mounted on /dev/mapper/-lv_root 78G 3.6G 71G 5% / tmpfs 7.8G 56K 7.8G 1% /dev/shm /dev/sda1 485M 32M 428M 7% /boot /dev/mapper/-lv_home 22G 314M 20G 2% /home [root@localhost ~]# fdisk -l /dev/sda 3. 磁盘已经有大容量然而新空间需要分配创建新的主要的分区为了执行此任务请输入这五命令 : p - 显示当前分区状态 n - 创建一个新的分区 p - 创建一个主要的分区 3 - 分区编号 w - 写入对磁盘的更改 [root@localhost ~]# fdisk /dev/sda
