^^^^ Why it is mapped through loop device?
Ensure that /dev/sdb1 is BLOCK device.
It seems to me that it is in fact just file created by mistake in /dev ...
(Then limited by tmpfs size to half of memory or so and explains strange size.)
Also use lsblk to verify real kernel sizes
(sometimes kernel see old partition size)
