我们在我们的群集上安装了Rocks 5.5发行版，并且想升级到6.2。 “/ export”分区安装在2个相同硬盘驱动器（HD）（/ dev / sdb和/ dev / sdc）的英特尔软件RAID 0arrays上，其余分区即“/”，“/ var”和在单独的（引导）HD或“/ dev / sda”上“交换”。
第一次升级尝试失败，因为警告说已经find房屋署的突袭资料，不能继续进行。 我天真地解决了这个问题，执行：
dmraid -r -E /dev/sda 错误没有再显示，我能够执行升级。 使用手动分区，我格式化了引导HD，并保持RAIDarrays未格式化并重新安装为“/ export”。
安装完成后，启动过程失败，说
ERROR: ddf1: Cannot find physical drive description on /dev/sdc! ERROR: ddf1: setting up RAID device /dev/sdc ERROR: ddf1: Cannot find physical drive description on /dev/sdb! ERROR: ddf1: setting up RAID device /dev/sdb /export1: The filesystem size (according to the superblock) is 488378000 blocks The physical size of the device is 244190638 blocks Either the superblock or partition table is likely to be corrupt!
在“救援”模式下启动Rock，我们可以再次安装硬盘，尽pipe它说RAID分区并没有被清除干净。
“dmraid”显示RAIDarrays，虽然有错误：
$ dmraid -r ERROR: ddf1: Cannot find physical drive description on /dev/sdc! ERROR: ddf1: setting up RAID device /dev/sdc ERROR: ddf1: Cannot find physical drive description on /dev/sdb!

这里是“fstab”：

和“blkid”：

还有“fdisk”输出：

我们可以访问“/ export”分区，其数据在“rescue”模式下仍然可用。
我很高兴知道是否有方法来重新构buildRAID元数据而不是格式化或删除/重buildarrays。
任何forms的帮助解决这个问题深表感谢。
