July 31, 2025Jul 31 Hi,Maybe someone will know the answer. I replaced a faulty 2tb hdd with a 4tb. The data-rebuild show 2tb being rebuild but I had to format it at the end.When it was done, unraid only showing me 2tb available on the disk.How can I have the 2tb missing back un the array hahaThanks in advance

The correct handling would have been to run a check filesystem on the drive. We normally recommend doing this before doing the rebuild. If you still have the drive that was replaced intact then you may still be able to get the data off that.

I see in the link you share that I can do a repair, I will try to do that and see if it will give me back the missing 2tb

So what I need to do, I will have to put back this drive, start the array, let him do the rebuild, remove it again, put back the 4tb, do the check filesystem to let unraid know its a 4tb instead of a 4tb and then launch the array and wait for the rebuild and then I will have the full 4tb available and not just 2tb?

Because now it feel like I bought a 4tb for nothing since its showing only 2tb available, the drive is empty haha
