Since you had two different things mounted on /home, it is unclear how
the system would interpret "umount /home". That is why I did not suggest
doing that.

 From the error, it seems that some checks got bypassed and a busy
filesystem was disconnected. It is likely that there is now some
filesystem corruption on /dev/vdb, and you should reboot with a forced
fsck to clean it up.  You really should track down the cause of the
extra mount of /dev/vdb on /home first, or the system will just come
up wrong again.
