that is one possibility.

even greater is op is a 'user', not 'root'.

_normally_ / most, if not all unix/linux systems, /home is owned by
'root'. which means *everything*, including a 'user' home
directory
is own by 'root'. therefore a 'user' running a normal user can
do
_nothing_ to his/her 'home' directory.

therefore a normal user *must* 'sudo' or 'su' to make changes to
users 'home' directory.

hth.

Another possibility is /home is a separate file system.  In that
case the OP does not want to "move it" but unmount it, change
the mount point in /etc/fstab, rmdir /home, and ln -s
new_mntpoint to /home.  Then mount it again.  Probably best
done is single user mode.

Here's a question to OP: how did you log into the system? If as *user*,
rather than as root, the filesystem is busy because you're logged on, and
in it.

Missed some of the posts overnight - has anyone asked for the o/p of df -h?
