正如标题所述,我的 mdadm RAID 正在从级别 6 迁移到级别 5,这时电源突然断电。不幸的是,我无法再重新组装阵列 - assemble 命令输出以下内容:
mdadm --assemble --force --run --verbose /dev/md0
mdadm: looking for devices for /dev/md0
mdadm: no RAID superblock on /dev/sde1
mdadm: /dev/sde1 has wrong uuid.

mdadm: /dev/sdb is identified as a member of /dev/md0, slot 2.
mdadm: /dev/sda1 is identified as a member of /dev/md0, slot 3.
mdadm:/dev/md0 has an active reshape - checking if critical section needs to be restored
mdadm: Failed to find backup of critical section
mdadm: Failed to restore critical section for reshape, sorry.
Possibly you needed to specify the --backup-file
该阵列位于 /dev/sda1 /dev/sdb /dev/sdd1 /dev/sde1 - 有什么办法可以恢复它吗?
