Disk full but have 50G

[BodgeIT]

I've got myself a little confused about my install.  I've installed to a watchguard XTM5.  I thought I had installed to a 50G harddisk but the other day while trying to install pfBlockerNG & ntopng my var partition filled up.
Here is output from df -i

I'm not sure why my 50g drive doesn't have a drive name and is just a gptid but I really don't know ebnough about Freebsd to work it out.

Here is output from df -h

I can see I have the 50G available but Im assuming it isnb't being used by the packages at all.

Can someone advise on how I can fix this?  Hoping I don't have to reinstall.
Thanks in advance.

/var is clearly a memory disk, so you most likely activated the RAM Disk Setting in System -> Advanced -> Misc. without understanding what it does.

Those devfs filesystems are virtual/pseudo filesystems for access to device nodes. They always show 100% full. You cannot write to them. Your 50GB drive is 2% full.
