I've brought this up before, but I don't recall a resolution to it.

We have an NFS-mounted filesystem, and git pull is choking on it.

% uname -a
Linux uhlr.zopyra.com 2.6.9-42.0.2.ELsmp #1 SMP Wed Aug 23 13:38:27 BST 2006 x86_64 x86_64 x86_64 GNU/Linux

It is a really old kernel... Maybe you could try with some of the
recent ones?

Could you please strace it? With strace -ff?

I looked through the archives of this list and did not see a final
resolution, other than a suspected bug in the OS NFS code.

Strace, just to be on the safe side

Ok, I've done the strace -ff.  It has generated 176 strace.out.<pid>
files.  I have placed a tarball of these files on my home server:

  http://www.zopyra.com/~rael/git/git-trace.tar.bz2

The file strace.out.25526 has, at the very end:

Yes, this is the file.

I extend the part you quoted. The file is opened here:

open(".git/objects/pack_awOTNW", O_RDWR|O_CREAT|O_EXCL, 0600) = 3
write(3, "PACK\0\0\0\2\0\0\3r", 12)     = 12
... lots of data. Counted writes: 488538...
write(3, "v\351\247V\325\362\327/\240\265\211\211\322,\261\210\301"..., 4096) = 4096
write(3, "\202\202g\232Bf\211Bf\261Bb\36X\22\4\364\365\25\22\223"..., 1114) = 1114
write(3, "M", 1)                        = 1

write(2, "Resolving 551 deltas.\n", 22)                               = 22
pread64(3, "", 242, 541) = 0

That's the problem.  Hmm... May I kindly suggest moving the topic to
linux-nfs (cc-ed along with lk)?
