扩展逻辑卷 - Proxmox 上的 Ubuntu

Question

将 Proxmox 虚拟机管理程序上的磁盘大小从 8GB 扩展到 18GB 后，我尝试在 Ubuntu 20.04 VM 上看到这个新空间：

这些是我在虚拟机上运行的命令

# Physical volume is called /dev/sda3
sudo pvs

# resize the Physical Volume (PV)
sudo pvresize /dev/sda3

# root logical volume is
df -h

# expand the logical volume
sudo lvextend -r -l +100%FREE /dev/mapper/ubuntu--vg-ubuntu--lv

# resize my number 3 partition (this gave me 17GB on sda3)
sudo growpart /dev/sda 3

我可以在sda3分区上看到它！

想看看 18GB 的/dev/mapper/ubuntu--vg-ubuntu--lv

任何指点都会很棒！

https://packetpushers.net/ubuntu-extend-your-default-lvm-space/是对我帮助最大的文章。

总之

# allocate more space on hypervisor

# make the partition see the space (dev/sda3, Resize, Write, quit)
sudo cfdisk

# extend the physical volume from the partition
sudo pvresize /dev/sda3

# extend LV to use up all space from VG
sudo lvextend -l +100%FREE /dev/ubuntu-vg/ubuntu-lv

# resize file system
sudo resize2fs /dev/ubuntu-vg/ubuntu-lv

# check can see the space on filesystem
df -h
