如何让Terraform修改Proxmox的scsi1存储而非Cloud-Init scsi0？

你的Terraform配置当前会默认修改scsi0设备（该设备被Cloud-Init占用），要改为修改scsi1驱动器，只需在磁盘配置中明确指定插槽，并确保启动盘设置正确，具体调整如下：

修改后的完整配置 #

resource "proxmox_vm_qemu" "fuse-pri" {
  name        = "fuse-pri"
  vmid        = "302"
  desc        = "Primary Fuse PostgreSQL DB - built by terraform"
  target_node = "pve"

  # VM Advanced General Settings
  onboot = true

  ### Clone (template name)
  clone      = var.rocky_vm_template
  full_clone = true

  # VM System Settings (important for QEMU agent). 
  # 因为模板未安装QEMU agent，所以设为"0"
  agent = 0

  # VM CPU Settings
  cores   = 8
  sockets = 1
  cpu     = "host"
  numa    = true

  # VM RAM Settings
  memory  = 16384
  balloon = 0

  # VM Network Settings
  network {
    bridge = "vmbr1" # 位于pfSense LAN
    model  = "virtio"
    tag    = 10
  }

  # VM Cloud-Init Settings
  os_type = "cloud-init"

  scsihw = "virtio-scsi-single"
  bootdisk = "scsi0" # 保持模板原有系统盘为启动盘

  # 指定磁盘挂载到scsi1插槽
  disk {
    slot     = 1
    size     = "100G"
    type     = "scsi"
    storage  = "supersonic"
    iothread = 1
    discard  = "on"
    ssd      = 1
    backup   = true
  }
}

关键调整说明 #

• 添加slot = 1：强制将该磁盘分配到scsi1插槽，避免覆盖模板中默认的scsi0设备（系统盘或Cloud-Init占用的设备）
• 保留bootdisk = "scsi0"：确保虚拟机从模板原有的系统盘启动，而非新增的scsi1磁盘
• 调整后，Terraform会在克隆模板的基础上新增scsi1磁盘并应用配置，Cloud-Init将继续使用模板默认的CD-ROM设备，不会被修改
