我目前正在从5个设备重build一个RAID6 MDADMarrays到9。
cat /proc/mdstat ：
Personalities : [raid6] [raid5] [raid4] md0 : active raid6 sde1[0] sdg1[9](F) sdh1[8](F) sdi1[6](F) sdj1[7](F) sdd1[4] sdc1[3] sdb1[5] sdf1[1] 2926751232 blocks super 1.2 level 6, 512k chunk, algorithm 2 [9/5] [UUUUU____] [>....................] reshape = 0.0% (112640/975583744) finish=142795.3min speed=113K/sec unused devices: <none>
mdadm --detail /dev/md0 ：

现在它显示我的新设备有问题。 我应该担心它build立一个无用的arrays吗？
这里是你必须遵循的步骤，以便首先重buildRAIDarrays，删除标记为“错误的备用重build”的分区。 使用fdisk创build新的RAID分区
然后执行以下命令
mdadm --manage /dev/md0 --add /dev/sdg1 mdadm --manage /dev/md0 --add /dev/sdh1 mdadm --manage /dev/md0 --add /dev/sdi1 mdadm --manage /dev/md0 --add /dev/sdj1
用cat /proc/mdstat监视重build过程
