Repositories

Disable Enterprise Repositories

1. Navigate to Node > Repositories. Disable the enterprise repositories.
2. Now click Add and enable the no-subscription repository. Finally, go to Updates > Refresh.
3. Upgrade your system by clicking Upgrade above the repository settings page.

local-lvm

Delete local-lvm and Resize local (read warning)

Warning: This assumes a fresh installation without advanced storage settings during the installation, such as ZFS. These steps are only recommended if you have a small boot drive and you need to reclaim space.

1. Delete local-lvm manually from web interface under Datacenter > Storage.
2. Run the following commands within Node > Shell.

lvremove /dev/pve/data
lvresize -l +100%FREE /dev/pve/root
resize2fs /dev/mapper/pve-root

2. Memory ballooning configuration: Disable

FAQ

安裝後無法正常開機

VFS: Unable to mount root fs on unknown-block(0,0)

Solution: 不要使用 Ventoy 方式安裝，改用 ISO 檔直接寫入 USB 方式。

系統突然不能正常開機

開機程序停在這個畫面

Loading Linux 6.17.13 ...
Loading initial ramdisk ...

原因：開機前可能有改過 kernel 的開機參數，不小心導致無法開機。

解決：

1. 使用 PVE ISO USB 開機
2. 進入 Advanced Options ➜ Rescue Boot
3. 修改 GRUB 開機參數 /etc/default/grub 

GRUB_TIMEOUT=5  # 0 改成 5, 方便以後管理
GRUB_CMDLINE_LINUX_DEFAULT="quiet amd_iommu=on iommu=pt"  # 移除有問題的參數

套用變更

update-grub
reboot
