I pursued this, but nothing had been deposited on /mnt or /media mount
points except my message file named "unmounted". 

I made the mistake of trying this on /, and so now I have this: 
/dev/disk/by-uuid/d3a2deb8-54f0-421e-9cd9-5cc90c3521fa on /
mounted twice. I assume this will disappear next boot, and hope that it
does no harm for the time being. 

What troubles me is that my root partition is nearly 500 Gb. df says:

    rootfs                       474440   474440          0 100% /
    /dev/disk/by-uuid/<UID of \> 474440   474440          0 100% /

But # du / -hx --max-depth=1 says "242M /" I picked up the opinion that
this discrepancy suggests filesystem corruption. Do you believe this to
be true? I suppose the only correction if so is to boot the system to
single user and run fdisk on /dev/sdb1. Not sure of the specifics.

I checked for deleted files being accessed and found that many dozen
firefox files were in
~/home/haines/.cache/mozilla/firefox/02ftk4dx.default/thumbnails/ .
But /home partition is broken out and so this not the problem of / being
filled. 

I also checked on usage of inodes:

 # df -i
        Filesystem            Inodes    IUsed    IFree IUse% Mounted on 
        rootfs                122880    13023   109857   11% /
        udev                  205730      629   205101    1% /dev
        tmpfs                 208326      759   207567    1% /run
        /dev/disk/by-uuid/... 122880    13023   109857   11% /
	...
