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

Your diagnostics could provide more information.

Thanks for the reminder. Any specific diag files you were looking or the whole zip?

Unless specified otherwise this will be what is wanted.

edit: deleted diag zip as issue has been resolved.

What is the problem exactly? Diags show 1.6TiB used, GUI should show 1.76TB.

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    .

du is known to often not give correct results on multi-drive btrfs format arrays.

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.

Thanks folks, I didn't know du had this limitation.
