Thanks for the responses. Just FYI that the bug was acknowledged, also it seems RH v5.3 does not have the problem... -----Original Message----- From: Jeff Moyer [mailto:jmoyer@xxxxxxxxxx] Sent: Wednesday, March 04, 2009 10:48 AM To: Qiuyang Wu Cc: linux-nfs@xxxxxxxxxxxxxxx; linux-fsdevel@xxxxxxxxxxxxxxx Subject: Re: pread/pwrite bug on linux?

I am not able to reproduce the problem. I tried with a RHEL 4 system, using exactly the kernel you listed (2.6.9-55.EL) on an i386 system. I tried against ext2, ext3, and an nfs mount exported from a RHEL 5 system. I should note that I modified your program to detect short writes and continue instead of reporting a bogus error. I'll reiterate that the value of errno is undefined if the library/system call did not return -1. I noticed that your test case used NFS. What NFS server were you using? Can you think of any other details that might affect the test?
