Is my Vera Plus running from the SSD?

I’ve had an SSD connected to my Vera Plus using a powered USB hub for several years and have used the extroot script to move the filesystem there. Yesterday the USB hub failed so I had to replace it. At the same time I updated the Vera firware to the latest 7.31. AFter doing that I tried again to use the SSD for the filesystem. But going to Settings → Logs and trying to Store logs on USB device (several times) I’m not sure where I stand. Using PuTTY to log in and look at filesystems this is what I see:
root@MiOS_xxxxxxxx:~# df -h

So where is the Vera running from? What is on the hub and what is on the SSD?
Also - where is the LuaUPnP.log file? There’s an old one in /tmp/log/cmh but I can’t find the current one. I know it’s out there somewhere because http://[my Vera IP address]/cgi-bin/cmh/ displays it in a browser.

It seems most of it is on your SSD, which is presumable ~30GB in size. /dev/sda1 and /dev/sda2 are partitions on this drive.

As the roots is using this drive, that’s where most things end up. Only /tmp is stored on it’s internal memory.
