Case:
Three 2TB hard disks are black label disks of western data. The model is: WD2003FYYS.The three hard disks made a set of RAID5 arrays, which stored the background management system of the plastic surgery hospital, mainly database files.The server failure occurred around 10 o’clock the night before. The customer service staff found that the background system was unable to log in and could not check any data. Then the staff of the network center went to the computer room to check it. It was found that there were two hard disks bright yellow lights, and RAID was in a state of collapse.
Solution:
It was found that a hard disk had a severe knocking sound, and there were no serious physical faults of the remaining two pieces.Then, for the structural characteristics of RAID5, we choose to analyze and combine data through the data of the remaining two disks without the bad disk, and finally extract the data.The database file is successfully recovered.
