You've got /dev/sdb and /dev/sdc mounted on top of each other. df sees
/dev/sdc because it's the one on top :) If you umount it you'll get
/dev/sdb. It happens.

I feel like the ext4 driver contains the ext3 and ext2 logic these days? I
found https://ext4.wiki.kernel.org/index.php/UpgradeToExt4 which says
"Note: The ext3 driver will be removed from the kernel in 4.3. The ext4
driver will mount ext3 volumes while maintaining ext3 disk format
compatibility." So, if you're on a new kernel, there you go.
