Case:
After the client’s server was crashing, the server was restarted to find that 3 plates were turned on, and the system could not start.
Solution:
According to the administrator, the server has been running for many years, and the system is MS Win2000. As for the array level administrator, it is unknown. In this case, it is necessary to analyze it. Processing process: When viewing the No. 0 sector, MBR is found to be normal. Based on this, it is analyzed. In the analysis, the XOR verification of the No. 6 disk cannot be passed. Instead, there are no problems with the other 5 plates. It is host, but there is data on the 6th. The size of the block was 16sec through the distance between DBR and MBR. In addition, it was found that there were many missing meta files of the first logic disk. There were even meta -file generated by the high version of the operating system. Look at the names of these files and found that it was owned by Winpe. PE has been installed in a logic disk, and two plates of yellow lights are on after the installation is completed (not clear why this operation is done). It seems that the first logic disk has been destroyed, and it cannot be used for reference. Directly locate each logic area, and after positioning to communicate with the user, it is roughly confirmed to be the DBR. Continue to look down and find the meta file. It seems that the logic D drive is normal. The analysis results were obtained through the analysis of the logic D plate file: 1. The size of the size of the size of the size of the size is correct 2 and 6. Reorganizing, when reorganizing, because of the use of the old version of RSTUIO, a lot of problems were used. Later, I confirmed that the analysis results were correct again. After replacing the RSUDIO version, the reorganization was OK. At this point, the data is successfully recovered.
