前几天，我的 CentOS 6.5 服务器的主驱动器出现故障。我们的托管公司更换了主驱动器并重新安装了操作系统。系统已启动并运行，但 15TB 的 RAID6 存储未安装。我需要帮助弄清楚如何安装它。我记得 95% 确定我使用 XFS 格式化了这个阵列，因为我在使 EXT4 工作时遇到了一些问题。
驱动器配置：
- 托架 0 包含启动 SSD (100GB)
- 托架 1-7 包含 3GB HD，构成 RAID6 阵列
- RAID 控制器是 LSI MegaRAID SAS 9260-8i
重新安装之前，最后的挂载配置是：
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/VolGroup-lv_root 50G 12G 36G 24% /
/dev/sdb1 485M 164M 296M 36% /boot
/dev/mapper/VolGroup-lv_home 53G 845M 49G 2% /home
/dev/sda1 14T 4.9T 8.0T 38% /home/gflftp/gflcontent
我记得两个 VolGroup 都安装在旧 SSD 上，然后我将 /dev/sda1 上的 RAID 阵列安装到子目录 /home/gflftp/gflcontent 中
当他们重新安装 CentOS 时，我最终得到了以下安装：
/dev/sdb2 on / type ext4 (rw)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
tmpfs on /dev/shm type tmpfs (rw)
/dev/sdb1 on /boot type ext4 (rw)
none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)

当我尝试挂载 /dev/vg_origin/lv_home 时，我得到了

mount: wrong fs type, bad option, bad superblock on /dev/mapper/vg_origin-lv_home,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try

作为数据是否仍在驱动器上的指标，请注意崩溃前的挂载日志：
