题库中原题为：

705.View Exhibit1 to examine the DATA disk group when all the disks are online.

Why is the rebalancing not performed and the content of the disk group not empty in Exhibit2?
A.Because the disk group is created with NORMAL redundancy
B.Because the disk repair time attribute is set to a nonzero value
C.Because the mirrored extents cannot be rebalanced across the other three disks
D.Because the other three disks have 60% free space, the disk rebalancing is delayed
Answer:D

争议点：
网上有人说选择B，比如“标记为正确答案，不看answer版”题库。

比如：
Riveore的解析：http://blog.csdn.net/rlhua/article/details/19845771

途中对比，发现第二文件的path没有了，题中问为什么没有重新平衡。
因为设置了DISK_REPAIR_TIME 参数，to repair the disk and bring it back online，推迟了重新平衡。
故选B。

本题考查 DISK_REPAIR_TIME 参数意义。

初步结论：
选择B。
