Folks, Another thought. Some of our profs here want to have their OD's mounted, then exported for all to use. Well, I tried the obvious: First mount the OD: mount -o rw /dev/od0a /PROFS (don't get IBM mad, but...) Now, since we export "/" to everyone, and /PROFS in part of the same FS, then it should be exported to, right? Well, wrong. After we do: exportfs -va we see "re-exporting /" But when we try to mount the OD from the remote machines, we get: "access denied" Do I have to put the export command in the /etc/exports file? Isn't there a way to do it manually for something you don't want to have looked for each time at bootup? On the remote machine we tried everything from: mount -v -t nfs -o rw <diskfull machine>:/PROFS /Users/<user>/Teach mount -v -t 4.3 -o rw <diskfull machine>:/PROFS /Users/<user>/Teach mount -v -t nfs -o rw,bg,noquota,net <diskfull machine>:/PROFS /Users/<user>/Teach mount -v -t 4.3 -o rw,bg,noquota,net <diskfull machine>:/PROFS /Users/<user>/Teach So, uhm, what did we do wrong? Thanks in advance! --Roger Jagoda --Cornell University --FQOJ@CORNELLA.CIT.CORNELL.EDU

Well, wrong. After we do: > > --Roger Jagoda No, you must export each file system separately. I.e. /dev/od0a represents an entire filesystem, that does not implicitly belong to /, it is simply mounted into /. You must use the command: exportfs /PROFS or put the line /PROFS into your /etc/exports file and use the command: exportfs. -Derek Ney sysdoc@boingo.med.jhu.edu

Did you create a mount directory or did you mount on the fly? You need a directory so that things work correctly... Well at least I think I did read something like this somewhere..

Well, I tried the obvious: [...] --Roger Jagoda --Cornell University --FQOJ@CORNELLA.CIT.CORNELL.EDU /* End of text from altair:comp.sys.next */ Have you (and the profs :-) considered that files on the optical are "owned" by whoever mounts the optical? That is, there is no file protection (distinction among owners) of files on the OD, as I understand it. This has the plus that one can take his private OD to another machine on which his login is different, and still use the files; it has a number of minuses for having multiple-users' files on an OD. Have you investigated what rwx permissions are needed to access these NFSed OD files? Jim Boyle
