The problem of entanglement operation of soft raid5,lvm,3t large hard disk

New server, 4 blocks of 3T large hard disk, soft RAID5 set up plus LVM partition various one-way operation ...

Sad reminder is after 4 days of soft raid rebuild, the final state to me fail, when the raid of "State:clean, FAILED", to cry without tears is the mood of me at that time.

Even more tragic is a pass mdadm remove this soft raid, after getting into the hard drive where one piece of my RAID build work was honored to be hung, with mkfs.ext4/dev/sde1:

/dev/sde1 is apparently on use by the system; Won't make a file system here!
