TrueNas Scale Bluefin dataset space error

[blackpeton]

Hello! I have a 2TB disk and create a pool on it. In the Storage dashboard it reports the available space is 1.5TiB but in the Datasets dashboard it shows that the available sapce for the dataset is only 1TiB. I use "df"、"zpool" commands and they report 1.5TiB free space correctly. What's wrong with the Datasets dashboard? When the dataset was freshly created, the available space was 2 TiB. Does it only show integer space in Datasets?

I've the same issue, with 4x4TiB.
Dashboard show 10.44TiB capacity (which seems correct) but dataset only show 6TiB...
Anyone has any information on this or how to reclaim missing space ?

Ok I think we are reading it wrong...

Actually in the dataset view `Available` means free space left and it's rounded, and on the dashboard it shows total space available without taking account of space used.

In my case I have 4x4TiB in raidz1 10.44TiB of total available space. I use 4.6 TiB of 10.44 TiB, so if you round all this values 4.6TiB ~= 5TiB and 10.44 - 4.6 = 5.84 TiB ~= 6 TiB, so the dataset view shows me 5TiB/6TiB which is actually correct..

I think the syntax [used] [/] [available] is not very explicit, i would rather use [used] [-]

or [used] [/] [total available]
The slash, imo, should more be used to express a quantity on a total quantity and not a quantity on space left, mathematically speaking I think it's misleading.

I hope it helps people who didn't understood this like this !​

In my previous reply i wanted to say: "i would rather use [used] [-] [ left] or [used] [/] [total available]"
[ left] without the space actually move down the the text XD
