Hello,
I was able to retrieve and attach the namespace for nvme0, nvme1 and nvme3. Now I have a new problem. All drives used to show as 2TB now nvme0/1/3 are showing 1.92TB, nvme2 which flashed correctly shows the correct size of 2TB. I am unable to add these back to my raid now as they are not the correct 2TB size. smartctl does not show any unallocated space. Is there any way to retrieve the lost space? The drives are all identical model and all functioned at 2tb size before the firmware update.
Below is the output of nvme0 (incorrect size) and then nvme2 (correct size):
debian# nvme attach-ns /dev/nvme0 -n 1 -c 0
attach-ns: Success, nsid:1
