This has got to be one of the most bogus things I've ever seen
involving NFS. I have two machines networked together:
Server: 2.2-stable from December 11
Client: -current from December 5
Client has mounted the /usr/ports tree from Server. On Client, I
chdir into /usr/ports/editors/emacs20 and start a build:
>> Checksum OK for emacs-20.2.tar.gz.
===> Extracting for emacs-20.2
===> emacs-20.2 depends on executable: gmake - found
Grind grind grind, the big tar extract starts crunching away. Since
it's emacs, it takes two forevers. Meanwhile, over on Server, I
decide to mount a CD-ROM. The CD is sitting in the drive, but it's
not mounted. I type "mount /cdrom" and it succeeds. BUT, at the same
time, over on Client everything suddenly falls apart:
/usr/bin/tar: Could not create file emacs-20.2/src/chpdef.h : Permission denied
/usr/bin/tar: Could not create file emacs-20.2/src/cm.h : Permission denied
/usr/bin/tar: Could not create file emacs-20.2/src/coding.h : Permission denied
followed by many more such complaints until the make dies. This
problem is reproducible.
It is hard to see why mounting a local CD-ROM on the NFS server should
cause problems for a completely separate exported file system, but
that is what is happening. The only connection between the CD-ROM and
NFS, as far as I can tell, is that /cdrom happens to be exported.
Suggestions, anyone?
