February 18, 20251 yr Hi everyone, I just added a new 16TB HDD that I precleared/erased to my array, when I first added the disk to the array it showed up as unsupported fs, I went to the bottom and formatted it and it now seems to be part of the array, but there is 306GB Used on the disk and I can't figure out where it is from. If I use shell to go into the directory there is no data at all there, why would there be data on this drive if its just been added? I don't have unbalance or my docker containers running or any VMs, not sure where it came from? Any possible ideas? I've made sure this disk was completely cleared, and the total size is correct. Specifically disk 8, I see about 500K writes but I'm not sure from what because the disk looks empty aincrad-diagnostics-20250217-2054.zip Edited February 18, 20251 yr by 97WaterPolo added another image

There is no data on the disk. The file system supports a lot of new features now that take up some space when the disk is formatted. Edited February 18, 20251 yr by Hoopster

Got it, thank you, I was wondering if I had messed up the formatting or had some partition on it that Unraid thought was occupied. That takes a good chunk of space for XFS though, I thought the main change for 7.0 was ZFS, which isn't my format? Do my other drives have it and I just don't realize it?

I don't remember exactly when XFS started taking much more space than it used to, but it has been about two years, I think. There are some posts in the forums about it as many started noticing what you did; a relatively large amount of space taken on a newly formatted disk.
