Final answer:
To rebuild a failed RAID without losing data, identify the failed drive, replace it, and initiate the rebuild process using RAID management software.
Step-by-step explanation:
To rebuild a failed RAID without losing data, you can follow these steps:
- Identify the failed RAID drive and remove it from the RAID array.
- Replace the failed drive with a new one.
- Use RAID management software to initiate the rebuild process.
- Allow the rebuild process to complete. This may take some time, depending on the size of the RAID array and the amount of data stored.
During the rebuild process, the data from the remaining drives is used to recreate the data on the new drive, ensuring that no data is lost. It is important to note that it is always recommended to have a backup of your data before attempting any RAID rebuild process.
