Keywords: HELP! Message-ID: <6936@uwm.edu> Date: 12 Oct 90 23:43:21 GMT Sender: news@uwm.edu Organization: University of Wisconsin, Milwaukee - Department of Mathematics Lines: 39 We've got a nice new RISC System/6000 model 530 here at UWM, which is on our local ethernet. On the same ethernet is our RT and about 15 6152 workstations, strung together with NFS. The RT has 330 Mb in it, and it's starting to get a little cramped. NFS has worked flawlessly to this point between the RT and 6152's (and even another RT on campus), so I figured that I would just export a directory on the 6000 and have a lot of megabytes of space to compile TeX in. I'm exporting /u and /usr on the 6000. The user directories are in /u. That's where I've got my temporary directory, too. I can successfully mount /u on the 6152's and read to my heart's content (at least so far), but if I try any major writes, I get locked in a NFS disk write on the 6152 (ps shows 'waiting for device I/O') and eventually I'll get "NFS server thales not responding... still trying" I've tried about six different configurations with /etc/fstab, all of which work fine from the RT. I've varied the block sizes, I've altered the retries and timeouts, I've tried soft vs hard.... I'm pulling my hair out. Nothing works. I finally set "intr" and can ^Z out of a task. When the task is suspended, I can do a "pwd" and suddenly I'll get "NFS server thales OK", but the instant I go back to the job, it starts to die again. It reads just fine but will write very little. I did *NOT* use SMIT to set up the NFS exports from thales, although they have been checked with SMIT and all appears fine. I simply created an /etc/exports file to my pleasing. Could this be a problem? Anyone else have a 6000 running NFS exports? Suggestions? Comments? ...
