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. SEK From: Steve Khoo Subject: NFS problem: Irix 5.2 server, 2.2-960501-SNAP client To: freebsd-current-digest@FreeBSD.ORG Date: Mon, 3 Jun 1996 18:48:31 -0700 (PDT) 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! SEK 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.
