New UFS volume created, 8% used immediately?

[Miel]

Hello there,

Just started setting up my very first NAS, managed to install it just fine. Importing my existing NTFS volumes was straightforward, but i'm having problems with a new set of drives i bought: have four 3tb drives, in a raid5 array (hw raid: highpoint rr2310). The array has been created ok, FreeNas sees the 9tb 'disk', and is able to create a UFS volume on it. However, the new volume is listed as having 8% space used immediately (7,4tb free, 8,1tb total).

I have a strong feeling that i'm overlooking something obvious here, i'm pretty new to freebsd, and sleep deprivation (side effect of new hardware ;) ) might have clouded my vision and common sense some more.

Hope someone can give me some pointers as to where my precious 700gb's went.

Hi Miel,

I'd bet that's the space reservation that FreeBSD automatically takes on a volume. It's basically the filesystem protecting itself from being run out of space.

Really? Does it really need 700gb for that?
I mean, that's a lot of midget**** i'm potentially missing out on! :)

Apparently, it does.
8% indeed.

Need. More. Disks!

Thanks Will :)
