我有一个包含两个物理卷的卷组设置。它工作正常，没有问题。我正在尝试添加 /dev/sda1 和 /dev/sdb1。如您所见，两者都已分区和格式化。前两个驱动器添加得很好，而其他两个驱动器却出现错误。
我真的已经走到了生命的尽头，我需要帮助。
此服务器的主要用途是作为文件服务器。它正在运行
Ubuntu 服务器 12.04.2
四个 SATA 驱动器，2x 500GB、1x 1TB 和 1x 2TB。
我在 2TB 上有一个单独的扩展分区，用于存放 ubuntu 及其所有需要的资料。我想将其余部分用作存放音乐、电影和照片的大型存储空间。
答案1
事实证明，sda1 和 sdb1 都保留了以前的卷组关联。我曾以为，我创建的第一个 vg 的所有痕迹（作为测试）都已被删除。但事实并非如此。为了擦除驱动器，我需要执行以下操作：
sudo pvremove /dev/sdb1 -ff
Labels on physical volume "/dev/sdb1" successfully wiped
之后，我能够通过pvcreate和成功重新添加驱动器vgextend。剩下的就轻而易举了。
