This is an odd problem. What does "df -n ." and "bdf ." say? Also "cd /tmp" and repeat the mkfifo stuff.

MKFIFO(1) BSD General Commands Manual MKFIFO(1)
NAME
mkfifo -- make fifos
SYNOPSIS
mkfifo [-m mode] fifo_name ...
DESCRIPTION
mkfifo creates the fifos requested, in the order specified. By default, the resulting fifos have mode 0666 (rw-rw-rw-), limited by the cur-
rent umask(2).
The options are as follows:
-m Set the file permission bits of newly-created fifos to mode, without respect to the current umask.
The mode is specified as in chmod(1). In symbolic mode strings, the ``+'' and ``-'' operators are interpreted relative to an assumed
initial mode of ``a=rw''
mkfifo requires write permission in the parent directory.
mkfifo exits with 0 if successful, and with >0 if an error occurred.
LEGACY DESCRIPTION
In legacy mode, the fifo's file permission bits are always limited by the current umask.
For more information about legacy mode, see compat(5).
SEE ALSO
mkdir(1), rm(1), umask(1), mkfifo(2), umask(2), compat(5), mknod(8)
STANDARDS
The mkfifo utility is expected to be IEEE Std 1003.2-1992 (``POSIX.2'') compliant.
HISTORY
mkfifo command appeared in 4.4BSD.
4.4BSD January 5, 1994 4.4BSD
