Raid recovery
RAID (Redundant Array of Independent Disks) is a technology that combines several physical disks into one logical data storage. It provides increased fault tolerance and productivity.
One of the main reasons for using RAID is the ability to restore data when one or more drives fail or fail. In such situations, it is possible to carry out the process of restoring the RAID array to preserve the integrity of the information.
Here are some steps to restore RAID arrays:
1. Investigate the error: If your RAID array has stopped working properly, the first thing you need to do is understand the cause of the failure. View system logs and hardware controller status messages (if used). This will help determine the specific type of error and offer a solution.
2. Replacing damaged discs: If the device indicates that some discs are damaged, replace these components with new working copies of the appropriate size and model.
3. Rebuilding/Regeneration: When a new disk is installed, the RAID controller will start the process of rebuilding or regeneration. During this process, the data from the damaged disk is copied to the new one.
4. Check the recovery status: Once the recovery operation is complete, check the status of the RAID array and its integrity. Make sure all components are working properly and there are no errors.
5. Create a data backup: To avoid information loss in the event of future problems with data storage systems (including possible failures of other drives), always make a backup copy of all important data on a reliable medium.
It is important to remember that each specific device has its own specific recovery method for a specific model/types of RAID arrays.
