nightmare file system n. pejorative hackerism for sun's network file
system nfs. in any nontrivial network of suns where there is a lot of
nfs cross-mounting, when one sun goes down, the others often freeze up.
some machine tries to access the down one, and getting no response
repeats indefinitely. this causes it to appear dead to some messages
what is actually happening is that it is locked up in what should have
been a brief excursion to a higher spl level. then another machine
tries to reach either the down machine or the pseudo-down machine, and
itself becomes pseudo-down. the first machine to discover the down one
is now trying both to access the down one and to respond to the
pseudo-down one, so it is even harder to reach. this situation snowballs
very quickly, and soon the entire network of machines is frozen -- worst
of all, the user can't even abort the file access that started the
problem many of nfs's problems are excused by partisans as being an
inevitable result of its statelessness, which is held to be a great
feature critics, of course, call it a great misfeature. its
partisans are apt to cite this as proof of unix's alleged bogosity; its
had a working nfs-like shared file system with none of these problems in
the early 1970s. see also broadcast storm.
