Help!!! I haven't got even one response. Am I the only one that have
this problem? Anyway, I tried the latest -current and rolled back to
2.1R and still see the same problem with both.
Thanks.

I have an interesting nfs problem...
The server is running irix 5.2 and the client is running
2.2-960501-SNAP. The mount exit without any error, but when I
do df, ls or pwd I get the following:
# df
Filesystem 1K-blocks Used Avail Capacity Mounted on
/dev/sd0a 49231 14290 31003 32% /
/dev/sd0s1f 1388387 446552 830765 35% /usr
/dev/sd0s1e 49231 797 44496 2% /var
procfs 4 4 0 100% /proc
hermes:/n/hermes 1468230 1316047 152183 90% /n/hermes
hermes:/n/hermes2 997025 867008 130016 87% /n/hermes2
delphi:/n/delphi 639048 639048 0 100% /n/delphi
delphi:/n/delphi2 639048 639048 0 100% /n/delphi2
# cd /n/delphi
# ls
ls: .: Not a directory
# pwd
pwd: Not a directory
#
The last two filesystems listed in df are the problem filesystems.
The funny thing is, I can nfs mount another SGI(hermes) also running
irix 5.2 without any problems. The server with problems(delphi) is a
Challenge S server and (hermes) is Indigo. The only difference I can
think of is, (hermes) was upgraded from irix 4.05 and the filesystem
was created in irix 4.05. All filesystems on (delphi) was created in
irix 5.2.
Any ideas?
I'd appreciate any help.
Thanks!

Thanks for the all responses and suggestions... It looks like the
problem is related to diskstriping on the Irix 5.2. We've been
playing around with diskstriping on the sgi to improve performance. I
truned off diskstriping and rebooted the sgi lastnight and all seems
to be fine now. I supposed it is possible that the sgi was somehow
hosed and rebooting fixed it. However, this is unlikely because nfs
mounts to other systems were still working; I did umount and mount on
sunos and hp machines to the sgi and worked without a problem. I'll
have to test it again with striping truned ON on the sgi later, just
to double check; Since this sgi is a production unit, I can't be
rebooting it too many times.
Anyway, we are pretty impressed with this P6 unit so far. We did some
benchmarking with a realworld example(we use a gcc cross-compiler for
embeded mips system and built one of our source tree), and here are
the resuls:
SGI 21 mins
P6(NFS) 16 mins
P6(local) 7 mins
The source tree is on the SGI server. P6(NFS) is the compile time for
the P6 with the source tree mounted via NFS from the SGI. P6(local)
is with the source tree copied over to a local disk on P6.
