Case:
Recovery type: Database recovery, Suida data recovery Customer Suda server uses the RAID0 array made of two Seagate 1TB hard disks, and the system suddenly appeared in the previous two days.
Solution:
The two hard disks were tested separately, and one of the hard disks could not be identified by one of the hard disks. It was damaged by firmware. After repairing the hard disk firmware, scanning the hard disk and a bad sector. The next time it took a few minutes to analyze the order and size of the RAID0 disk and size.Establish a virtual array, open the D drive where Suda Software is located, and extract the account set database file in the data directory. There are more than ten account sets. Among them, the more critical account set database MDF file encountered a bad sector when exporting, resultingThe database cannot be attached, and the database lightning repair technology developed by our company is successfully repaired.Engineers suggest that the database file is lost and repaired immediately. Do not do reinstallation software or restore the operation of previous database backup files. This will cause secondary damage.The data cannot be restored completely; in addition, the key business data server should try not to use RAID0 when doing the array, because the RAID0 array is mainly to increase the capacity and speed, and the security is too poor.
