先增加硬碟空間: 在 Proxmox 頁面，點 vm, hardware, Disk Action, 選 Resize：
輸入要增加的數量:
到 ubuntu 終端機，先檢查 :
lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINTS
sda 8:0 0 32G 0 disk
├─sda1 8:1 0 1M 0 part
├─sda2 8:2 0 513M 0 part /boot/efi
└─sda3 8:3 0 19.5G 0 part /
sr0 11:0 1 1024M 0 rom
已經增加到32G，但 sda3 只用到 19.5G
安裝 : growpart
sudo apt install cloud-guest-utils -y
執行:
sudo growpart /dev/sda 3
(!!! /dev/sda 3 <- — sda 跟 3 之間空一格)
CHANGED: partition=3 start=1054720 old: size=40886272 end=41940992 new: size=66054111 end=67108831
再執行 ：
sudo resize2fs /dev/sda3
resize2fs 1.46.5 (30-Dec-2021)
Filesystem at /dev/sda3 is mounted on /; on-line resizing required
old_desc_blocks = 3, new_desc_blocks = 4
The filesystem on /dev/sda3 is now 8256763 (4k) blocks long.
改好了。
再檢查一次:
lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINTS
sda 8:0 0 32G 0 disk
├─sda1 8:1 0 1M 0 part
├─sda2 8:2 0 513M 0 part /boot/efi
└─sda3 8:3 0 31.5G 0 part /
sr0 11:0 1 1024M 0 rom
sda4 有 31.5G 了.
df -h /
Filesystem Size Used Avail Use% Mounted on
/dev/sda3 31G 9.0G 21G 31% /
lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINTS
sda 8:0 0 32G 0 disk
├─sda1 8:1 0 1M 0 part
├─sda2 8:2 0 513M 0 part /boot/efi
└─sda3 8:3 0 31.5G 0 part /
sr0 11:0 1 1024M 0 rom
完工
