    • degraded RAID1 recovery from QNAP

      Hello,

      I have 2x Seagate 8TB that was installed in a QNAP TS-251+ System before. Configured as 2 "Single"-drives but it seems QNAP create a "pseudo" raid? Now I want to integrate into my new OMV-4 system without dataloss. I have a Backup but there ist much data (about 10 TB) to copy, so I want to avoid this.


      Is there any possibilty to revover this?


      Attached the array and disk information acc. Degraded or missing raid array questions below:
