我被重定向到这里问库本图。
我工作的服务器上的操作系统安装在 SSD 上,但数据存储在 RAID 系统中设置的内部硬盘上。最近,我在启动时无法安装 RAID 系统,而操作系统加载正常。我怀疑技术人员在服务器运行时撞到了服务器,因为机箱上有划痕,但我不确定。
当我启动计算机时,我收到错误消息(和The drive for /home is not ready or present
的消息相同。我进入恢复 shell 并按照帖子中的建议运行/Data
/Backup
fsck -A
这里/
,但我收到的是忙音消息。
然后我启动到恢复模式并运行fsck -A
,但我收到消息
fsck.ext4: Unable to resolve 'UUID=334eef34-16c4-45ec-9cc9-5f40e9f8207d'
fsck.ext4: Unable to resolve 'UUID=19bf1002-fa4b-4462-9ea6-807d5b0f312b'
fsck.ext4: Unable to resolve 'UUID=0f556fa7-b061-4c22-b84b-97e2e3f1b545'
在ubuntu论坛我找到了编辑的建议/etc/fstab
,但是我对此感到力不从心,因为我真的不明白我在搞什么。
运行blkid

我注意到缺失的 UUID 与 中的相同,/etc/fstab/
但与 中的不匹配blkid
。有没有办法找出哪个 UUID 去了哪里并恢复文件系统?
绝大多数都已备份,因此损害并不大,但有几样东西希望能够恢复。
我在装有 Ubuntu 14.04.5 LTS 的服务器上工作,如果这有区别的话。
