wangjangle Posted January 11, 2022 Share Posted January 11, 2022 Hey all, not sure what I'm missing here but the disk space available on my SSD pool isn't matching everywhere. From a 2x1TB BTRFS RAID0 Pool named ssd unRAID "Main" tab disk details reports: Data, RAID0: total=1.65TiB, used=1.64TiB (this seems to match above) root@Tower:/mnt/ssd# df -h /mnt/ssd Filesystem Size Used Avail Use% Mounted on /dev/nvme0n1p1 1.9T 1.7T 171G 91% /mnt/ssd Where is that 200GB extra being used? root@Tower:/mnt/ssd# du -h . [..] 1.4T /mnt/ssd Cheers Quote Link to comment

JorgeB Posted January 12, 2022 Share Posted January 12, 2022 What is the problem exactly? Diags show 1.6TiB used, GUI should show 1.76TB. Quote Link to comment
wangjangle Posted January 12, 2022 Author Share Posted January 12, 2022 (edited) I'm trying to see where the space is actually being used, since du reports a value 200GB lower. root@Tower:/mnt/ssd# du -sh . 1.4T . Edited January 12, 2022 by wangjangle Quote Link to comment

Correct, missed du output above, it's not reliable with btfs, even with a single device fs, GUI and df will show the correct used/free space for that pool. Quote Link to comment
wangjangle Posted January 12, 2022 Author Share Posted January 12, 2022 Thanks folks, I didn't know du had this limitation. Quote Link to comment
