自制支持 SATA 控制器的 box

UPDATE: 无需自制 box，通过配置新增 SATA 即可. 参考: https://stackoverflow.com/questions/21574260/change-default-disk-controller-in-vagrant

        (1..3).each do |k|
          node_disk = "./itop-mgr-#{i}/node_disk#{k}.vdi"
          unless File.exists?(node_disk)
            v.customize ['createhd', '--filename', node_disk, '--size', 1 * 5120]
          end
		  #v.customize ["storagectl", :id, "--name", "IDE", "--remove"]
		  v.customize ["storagectl", :id, "--name", "SATA", "--add", "sata"]
          v.customize ['storageattach', :id,  '--storagectl', 'SATA', '--port', "#{k}", '--device', 0, '--type', 'hdd', '--medium', node_disk]
        end

基于 centos/7 启动一个 vm

vagrant init centos/7
vagrant up

修复 keypair

制作 box 时禁止 insert_key，添加 config.ssh.insert_key = false，否则会报 Authentication failure. Retrying...

Vagrant.configure("2") do |config|
  config.vm.box = "centos/7"
  config.ssh.insert_key = false
end

参见：

关机，在 virtualbox 图形界面添加 SATA 控制器。执行以下命令导出 box

 vagrant.exe package

Vagrant 将创建名为 package.box 的新的 box，此后我们便可以使用该 package.box 作为其他虚拟机的基础 box 了。另外，如果当前处于 Vagrantfile 文件所在目录，则可简化创建命令：

vagrant package

add box

vagrant.exe box add package.box --name=centos-sata/7

安装 vagrant-vbguest

vagrant.exe plugin install vagrant-vbguest

解决如下报错

Vagrant was unable to mount VirtualBox shared folders. This is usually
because the filesystem "vboxsf" is not available. This filesystem is
made available via the VirtualBox Guest Additions and kernel module.
Please verify that these guest additions are properly installed in the
guest. This is not a bug in Vagrant and is usually caused by a faulty
Vagrant box. For context, the command attempted was:

vagrant-vbguest 不支持 kernel-ml 内核，临时解决方案，编辑 .vagrant.d\gems\2.4.6\gems\vagrant-vbguest-0.19.0\lib\vagrant-vbguest\installers，将 install 命令改为

@has_kernel_devel_info = communicate.test('test -e /usr/src/kernels/`uname -r`', sudo: true)

相关 issue：dotless-de/vagrant-vbguest#325 不知道为什么被标记成 wontfix

VirtualBox Guest Additions 6.0.4. 在 kernel 5.2 下编译报错

An error occurred during installation of VirtualBox Guest Additions 6.0.4. Some functionality may not work as intended.

see: https://www.virtualbox.org/ticket/18515 升级 virtualbox 到最新版。

不安装 VirtualBox Guest Additions

node.vm.synced_folder ".", "/vagrant", disabled: true
if Vagrant.has_plugin?("vagrant-vbguest")
  node.vbguest.auto_update = false
end

管理硬盘

直接删除硬盘文件，会报错：VERR_ALREADY_EXISTS，需通过 VBOXmanage 删除

VBoxManage.exe list hdds
VBoxManage.exe closemedium disk /e/dev/ceph-learn/node-2/node_disk1.vdi --delete

ceph-deploy

指定国内 repo 或者使用 --no-adjust-repos 参数不修改repo，直接使用/etc/yum.repos.d/ceph.repo。

ceph-deploy install --repo-url https://mirrors.aliyun.com/ceph/rpm-nautilus/el7 --gpg-url https://mirrors.aliyun.com/ceph/keys/release.asc node-1

# ceph-deploy install --help
...
--no-adjust-repos     install packages without modifying source repos

重新创建 osd

# lvremove 
# vgremove ceph ...
