运行旧的科学Linux 6.0的服务器在重新启动期间受到来自启用的networking启动的损害，试图从同一子网中的应用服务器加载一些垃圾（我看到他在一个旧的novell安装过程中卡住了某处）。 重新启动结束在grub菜单，但没有可用的磁盘（找不到任何分区或内核，只是重新安装grub）。 操作系统和数据分区在一个RAID上，configuration为两个卷，操作系统为RAID 1，数据为RAID 5。 我启动到一个现场系统，至less可以看到卷：
[root@livecd dev]# gdisk /dev/sdb GPT fdisk (gdisk) version 0.8.4 Partition table scan: MBR: MBR only BSD: not present APM: not present GPT: present Found valid MBR and GPT. Which do you want to use? 1 - MBR 2 - GPT 3 - Create blank GPT Your answer: 2 Using GPT and creating fresh protective MBR. Command (? for help): i Partition number (1-2): 1 Partition GUID code: EBD0A0A2-B9E5-4433-87C0-68B6B72699C7 (Microsoft basic data) Partition unique GUID: BC2FE104-31B6-4E92-9DBF-B0C4DD581804 First sector: 999424 (at 488.0 MiB) Last sector: 9765625855 (at 4.5 TiB) Partition size: 9764626432 sectors (4.5 TiB) Attribute flags: 0000000000000000 Partition name: '' 类似于分手：
[root@livecd dev]# parted /dev/sdb print Warning: /dev/sdb contains GPT signatures, indicating that it has a GPT table. However, it does not have a valid fake msdos partition table, as it should. Perhaps it was corrupted -- possibly by a program that doesn't understand GPT partition tables. Or perhaps you deleted the GPT table, and are now using an msdos partition table. Is this a GPT partition table? Yes/No? Yes Model: SMC SMC2108 (scsi) Disk /dev/sdb: 9995GB Sector size (logical/physical): 512B/512B Partition Table: gpt Number Start End Size File system Name Flags 1 512MB 5000GB 4999GB ext4 2 5000GB 9995GB 4995GB ext4
/ proc /分区只显示我原始设备（sda + sdb），从来没有设备，我可以挂载为ext4（sdb1，sdb2）。 lsblk只显示整个磁盘：
[root@livecd dev]# lsblk -t /dev/sdb NAME ALIGNMENT MIN-IO OPT-IO PHY-SEC LOG-SEC ROTA SCHED RQ-SIZE RA sdb 0 512 0 512 512 1 cfq 128 128
（没有blkid）。 有没有机会从两个sdb分区获取数据，我只能得到他们的部分唯一的GUID，但不能使用这些来挂载设备。
非常感谢任何提示如何访问数据！
