3.1 EVE模拟器2.0.3-92: 分区扩展EVE-NG的硬盘容量（50GB扩展为2TB）

3.1 EVE模拟器2.0.3-92: 分区扩展EVE-NG的硬盘容量（50GB扩展为2TB）

查看硬盘的容量df -Th

dev/mapper/eve--ng--vg-root，所以我们只要把这个LV容量扩大即可

给EVE-NG硬盘扩大容量，对于EVE-NG来说，相当于加大物理磁盘容量\
注意：无法扩展具有快照的虚拟机中的磁盘，必须删除快照。ESXi上的虚拟机主机，可以使用VMware Workstation连接配置扩展硬盘空间。

EVE-NG系统层面增大VG容量

加电开机EVE-NG，确认硬盘容量为2000G

给硬盘sda分区

root@zh-cjh:~# fdisk /dev/sda

Welcome to fdisk (util-linux 2.27.1).

Changes will remain in memory only, until you decide to write them.

Be careful before using the write command.

Command (m for help): n

Partition type

   p   primary (1 primary, 1 extended, 2 free)

   l   logical (numbered from 5)

Select (default p): p

Partition number (3,4, default 3): 3

First sector (999424-4194303999, default 999424): 83884032

#（sda3的start sector，该值是sda2的end sector值 +1）

Last sector, +sectors or +size{K,M,G,T,P} (83884032-4194303999, default 4194303999): 回车

# 由于sda1与sda2中间的一些sector没有使用，所以First sector提示的default是999424

Created a new partition 3 of type 'Linux' and of size 1.9 TiB.

Partition table entries are not in disk order.

Command (m for help): w

The partition table has been altered.

Calling ioctl() to re-read partition table.

Re-reading the partition table failed.: Device or resource busy

The kernel still uses the old table. The new table will be used at the next reboot or after you run partprobe(8) or kpartx(8).

root@zh-cjh:~# reboot

（重启，使分区生效）

将sda3加入到VG中

查看VG的名字

扩容LV

查看LV路径

root@zh-cjh:~#  lvdisplay

将剩余容量扩容到/dev/eve-ng-vg/root路径下

root@eve-ng:~# lvextend -l +100%FREE /dev/eve-ng-vg/root

  Size of logical volume eve-ng-vg/root changed from 41.52 GiB (10629 extents) to 1.94 TiB (509829 extents).

  Logical volume root successfully resized.

root@eve-ng:~#

重新定义文件系统大小

root@zh-cjh:~# resize2fs /dev/eve-ng-vg/root

完成。

可以看到，硬件空间的使用率为2%，说明空间足够大了。
