What if a hard disk of Qunhui shr is broken?

SHR can be understood as RAID5 mode that allows different hard disk capacities. If a hard disk (less than or equal to the average capacity of all hard disks) is broken, you can directly replace it with a new hard disk, and then wait about 5~ 10 hours to rebuild the file system, and you can use it normally.

If two pieces are broken at the same time, or one piece is broken during file system reconstruction, data loss is inevitable. So generally speaking, SHR or RAID5 is more suitable for hard disk groups with less than 8 blocks. If there are more, the security risk will be great.
