I had an issue in creating a JBOD pool

So I created a JBOD volume pool with NAS TS-453Be.

Non initially I don't understand how JBOD works after it is created, but there we're an issue that makes me check one of the disk by removing them while the system is still on. It was a JBOD of 1 TB not that much, a accumulation of 2 (500gb) HDD. With that small maneuver I did by removing one of the disc while the NAS was still on, the system cannot rebuild the JBOD volume from the two disks, thus rendering the JBOD pool inactive and unaccessible.

Regaining this has simply become out of the option for some reason, from the manual too, it said that it is required to create a new JBOD pool.

Now come to the question, can I create the new JBOD with the same HDD, that is occupied(/has data), and not lose any of those data? Because the HDD is still in good health. It just wont read the data. How should I do this?

    Hello Abdul,

    Thank you for your question and for reaching out with your question today.

    Creating a new JBOD pool with the same HDDs that were previously part of a failed JBOD pool can be risky, as it might lead to data loss if not done correctly. However, if the disks are still in good health and you haven't performed any additional actions on them since the JBOD failure, there might be a chance to recover the data by recreating the JBOD pool with the same disks. Keep in mind that there are no guarantees, and it's always advisable to have a backup of your important data before attempting any recovery process.

    Here are some steps you can try to recreate the JBOD pool without losing the data:

    1. Make Sure the NAS and Drives Are Stable: Before attempting any recovery, ensure that the NAS and drives are stable and in good condition. If there are any signs of hardware issues or failures, it's best to consult with the NAS manufacturer's support or a professional data recovery service.
    2. Identify the Drives in the JBOD Pool: Make sure you correctly identify the drives that were part of the original JBOD pool. If possible, label the drives to avoid confusion.
    3. Power Off the NAS: Safely shut down the NAS and remove all the drives from it.
    4. Keep the Drives in the Same Order: When recreating the JBOD pool, ensure that you place the drives in the same order they were in before the failure. This is crucial to maintain data integrity.
    5. Recreate the JBOD Pool: Once the drives are reinserted in the NAS, access the NAS configuration settings and create a new JBOD pool using the same drives. Some NAS systems might automatically detect the previously used configuration, while others might require you to manually create the JBOD pool.
    6. Scan for the Data: After recreating the JBOD pool, check if your data is accessible. If it is, make a backup of the data immediately.
    7. Data Recovery Software (Optional): If the data is not accessible after recreating the JBOD pool, you might consider using data recovery software specifically designed for NAS systems to attempt data retrieval. There are third-party data recovery tools that might help you recover data from failed JBOD pools.
    8. Seek Professional Assistance (Last Resort): If all else fails, or if you are uncertain about the recovery process, it's best to consult with professional data recovery services that specialize in NAS systems.

    Remember that any attempt to recover data carries some risk, and there's no guarantee of success. It's crucial to be cautious and seek professional assistance if needed to avoid potential data loss. Additionally, learning from this experience, ensure that you have a proper backup strategy in place to protect your data from future issues.
