Message-ID: <1989Sep28.145106.3723@tubsibr.uucp> Date: 28 Sep 89 14:51:06 GMT Sender: petri@tubsibr.uucp (Stefan Petri) Reply-To: petri@tubsibr.UUCP (Stefan Petri) Organization: TU Braunschweig, Informatik, Bueltenweg, W. Germany Lines: 45 Configuration : Targon/35-M50 with TOS3.2 and NFS3.2 (thats a clone of Pyramid 9810 OSx4.0 , I think) linked via ethernet to some Sun3/60 (SunOs 3.5 and 4.0.3) Today I tried for the first time to import a filesystem via nfs : # mkdir /usr/mnt # mount mplsun:/usr/users /usr/mnt /usr/mnt: not owner -> what does this mean ? # mount /dev/iop/pdisk00a on / type 4.2 (rw,noquota) /dev/iop/pdisk00k on /usr type 4.2 (rw,noquota) /dev/iop/pdisk00l on /u1 type 4.2 (rw,noquota) /dev/iop/pdisk00e on /u2 type 4.2 (rw,noquota) mplsun:/usr/users/mplsun on /usr/mnt type nfs (rw) -> I think, the mount succeeded # ls -a /usr/mnt # -> The ls did'nt even show "." and ".." ! # ls -ld /usr/mnt drwxr-xr-x 14 root 512 Sep 22 13:39 /usr/mnt -> The 14 links are correct for the mounted filesystem. And then : (our root-account is in the att-universe) # ucb ls -aC /usr/mnt . bluemel jabs lost+found schmidt .. broeke klebsch meier tmp bachmann forth linde moeller -> This gives the correct entrys. I wrote some programs to test the stat(2-att), fstat(2-att), stat(2-ucb) and fstat(2-ucb) Systemcalls. They all work on the remote-mounted FS. What doesn't work is the readdir(3X-att) call, opposed to the readdir(3-ucb) call. I think, this kind is of transparency isn't what they call network-transparent- filesystem ?
