我正在尝试将第二个 SSD 添加到 Centos 6 系统。但我Error 5 partition table invalid or corrupt在启动时遇到了这个问题。
系统已在 RAID 1 阵列中拥有单个 SSD (sdb) 和一对 HDD (sd{a,c})，系统从该阵列启动。就好像新的 SSD 假定为 RAID 阵列的设备之一。是吗？如何避免这种情况或重新安排设置？

答案1
我无法直接修复它，因此我拿出新的 SSD 并将其安装在我的桌面上，然后对其进行分区和格式化。
然后在服务器中我编辑了fstab对旧 SSD 行的注释并添加了一个具有通用设备规格的新行：
#UUID=72552a7a-d8ae-4f0a-8917-b75a6239ce9f /ssd ext4 discard,relatime 1 2
/dev/sdb1 /ssd ext4 discard,relatime 1 2
然后我关闭了服务器，并将旧的 SSD 换成了新的。
重新启动后，我编辑了相应 UUID 的设备规格：
$ ll /dev/disk/by-uuid/

新的fstab：
#UUID=72552a7a-d8ae-4f0a-8917-b75a6239ce9f /ssd ext4 discard,relatime 1 2

重新引导一次就完成了。
