Re: [Samba] Text File Corruption Writing from Windows to Linux NFS Share.
Yes, I did. I tried them separately and together. Made no difference. Any text file copied to a SFU share has each byte replaced with a null character. Any PDF (or zip or exe) file copied fails to copy. I'm going to turn debug up to about 10 and stare at it some more. Perhaps I can find a test case that will tell me something. S.H.H.

Perhaps I can find a test case that will tell me something. What we'd need then is sniffs of the relevant network segments taken at the exact same time, plus some time for possible deferred caching. Ah, one more hint: You might want to try the syncops vfs module.

Re: [Samba] Text File Corruption Writing from Windows to Linux NFS Share.
No, sendfile is not enabled. The default is false, and I haven't changed it. S.H.H.

[Samba] Text File Corruption Writing from Windows to Linux NFS Share.
I am running a Windows 2003 Server with Microsoft Services for UNIX (SFU) installed which is serving NFS shares to a Redhat Enterprise Workstation v5 Linux machine which is running Samba 3.0.33-3.7.el5. There is also a Solaris 5.6 workstation serving NFS shares. All of these are mounted on the RHEL machine and are visible to Samba. I can read and copy anything from any share using Windows Explorer to my Windows XP Pro machine. I can copy to and/or write anything I want on the Solaris shares. If I attempt to write a PDF file to any of the SFU shares, the write fails with a Windows message that either the file is busy (which it is not) or the share does not have write permissions (which it does). If I attempt to copy a text file to this same share using Windows Explorer, the copy succeeds. However the contents of the file is lost leaving only a stream of null characters. If I attempt to edit a text file on any of the SFU shares, the contents of the file is replaced by a bunch of null characters. Yet, if I use Cygwin on the same XP Pro machine to copy the same text file from the same Windows directory to the same SFU share via Samba, the copy works just fine. Do SFU shares need to be mounted with some special switch on the RHEL machine for Samba to be able to write to them? Is there some obscure Samba configuration switch that I've missed? Any help that might point me in the right direction would be appreciated. Thank you.

You use Samba to re-export this to a Windows XP machine. You get file corruption when writing to that samba export. Right? Question: Why don't you just mount directly from W2k3? And, you might just try posix locking = no and kernel oplocks = no in your smb.conf.

The Windows 2003 machine is a raid array data server that provides both Windows and UNIX/Linux shares (NFS). Some users prefer a Windows browser for copying or editing files. An older Samba on an older Linux machine (Mandrake 10.2) provided this service until recently. S.H.H.
