I have read all the threads on git having trouble with pread() and I  
didn't see anything to help.

Situation:
   git commands run on system "dev2" which is Linux 2.6.9-42.0.8.ELsmp  
on an NFS mounted directory.
   The NFS server is "dev1" which is Linux 2.4.28

I get the following output from git when doing a fetch:
   remote: Counting objects: 406, done.
   remote: Compressing objects: 100% (198/198), done.
   remote: Total 253 (delta 127), reused 150 (delta 55)
   Receiving objects: 100% (253/253), 5.27 MiB | 9136 KiB/s, done.
   fatal: cannot pread pack file: No such file or directory
   fatal: index-pack failed

The end of the strace looks like so:
pread(3, "", 205, 1373)                 = 0
write(2, "fatal: cannot pread pack file: N"..., 57) = 57

I have ran strace -o /somedir/q -ff git fetch and have the straces  
available at:
http://docwhat.gerf.org/files/tmp/git-strace-20080626.tgz

I have worked around the problem by running the fetch from the nfs  
server.

It looks like I can recreate this at will and I'm willing to help  
figure this out.

Thanks!

Ciao!
