Qnap downgrade firmware upgrade#

Whilst mdadm -E /dev/sda3 showed me that a superblock was available for /dev/sda3, that wasn’t the case for /dev/sdb3. Mdadm -E /dev/md0 confirmed the issue, no RAID0 volume even though I did a restore of the QNAP’s configuration settings. I SSH’ed in the QNAP device and triggered some mdadm commands as shown on the screenshot below. The restore process went flawlessly but upon reboot, I had the same problem, my RAID0 volume was still gone. Fist thing I tried is a restore of the latest known working backup of my QNAP storage device. Hopefully I had a backup and a lot of spare time thus I could play around with the device. It took me some time to recover my broken RAID0 volume and many trial and errors. By the way did you know that with the latest beta firmware, your QNAP device can copy your data to a SaaS (Storage as a Service) provider in the Cloud, cool isn’t it 🙂 My data is important and I had everything rsync’ed on another QNAP TS-639 Pro storage device but still it is pain in the a***. The two WDC VelociRaptor disks were supposed to form a single RAID0 volume, well it used to be just before the firmware upgrade…Īs an old saying goes, if your data is important backup once, if your data is critical backup twice. So I was left with three stand alone disks as shown on the screenshot above.

I did a simple firmware upgrade and whoop my RAID0 volume was gone, oops! Something like four weeks ago I had a major issue with my QNAP TS-459 Pro storage device.
