fails, replace the hard disk. Remember, you cannot pull out other undamaged hard drives in
the RAID group at will.
RAID rebuilding conditions and precautions:
1. RAID 3/5/10 mode cannot have more than two defective hard disks at the same time.
RAID 1 only allows one to be defective. If exceeded, the data cannot be recovered. Other
RAID modes do not support rebuilding.
2. Clone Mode, as long as one hard disk is intact, the files of this hard disk can be completely
cloned to the newly inserted hard disk.
3. When replacing the hard disk, please turn off the computer first. For example, if the hard
disk is pulled out while the computer is in the RAID group, the data may be damaged or the
recovered data may be incomplete and unusable.
4. The new hard disk must be greater than or equal to the smallest capacity of the hard disks
in the original RAID5. Cannot replace with hard disks that have already have RAID setting.
5. After replacing the hard disk and powering on, you need to wait a few minutes for the
system to start the rebuilding process. During this wait period, if any hard disk is unplugged,
the RAID information of the original RAID group will be damaged. Once the RAID
information is damaged, the rebuilding process cannot be started again and all data will be
damaged.
