因此,我一直在研究 OpenStack,并注意到创建的 cinder 卷只有 20GB。我需要增加它(或者至少我 99% 确定我需要增加它 :) )
正在查看系统
目前这是 vgs 的状态
[root@openstack ~]# vgs

centos_openstack 3 3 0 wz--n- 5.46t 60.00m
cinder-volumes 1 2 0 wz--n- 20.60g 612.00m
这是物理卷本身

这是整个文件系统。

所以基本上我的最终目标是让 cinder-volumes 拥有大约 5T 的空间,并让 centos_openstack 拥有剩余的半 TB。
我在网上搜索时发现了这个指导。但我基本上是太害怕去遵循它...就像没有看到 /dev/loop1 作为挂载点,df -h
以及不明白为什么 5.5TB 在 centos_openstack 挂载中以及如何减少该大小以将其提供给 cinder-volumes。
无论如何,TL;DR --- 我太害怕去做我想做的事情了,如果有人能帮助指导我实现最终目标(使 Cinder 卷大小达到约 5TB),我将不胜感激
