<div dir="ltr"><br><div class="gmail_extra">I guess the reason for this big difference in write v/s rewrite in win7 performance could be, the fact that we don't implement fallocate() method in vfs_glusterfs. If the client (e.g win7) requests guaranteed reservation of space before initiating the write, then Samba falls back to the crude method of writing zeroes to the file for the full size even before accepting the first write call from the client. I am assuming the linux cifs client does not care about reservation of space and therefore Samba does not execute the zero-writing fallacote fallback.</div>

also the overhead information for keeping track of
where the data is located on the storage media. This
overhead is called the “metadata” It consists of the
directory information, the space allocation and any
other data associated with a file that is not part of
the data contained in the file. It is normal for the
initial write performance to be lower than the
performance of re- writing a file due to this overhead
information. </span></p>

<br>
When we are using same samba share on windows and Linux, the only
thing different is "unix extensions" support in Linux which Linux
uses by default. However I don't think "unix extension" has anything
to do with performance of writes and rewrites. I only guess is the
samba client in Linux is works well with samba than the Microsoft's
smb client which is in windows 7.<br>
<p>"unix extensions" parameter controls whether Samba
implements the CIFS UNIX extensions. These extensions enable Samba
to better serve UNIX CIFS clients by supporting features such as
symbolic links, hard links, etc... These extensions require a
similarly enabled client, and are of no current use to Windows
clients.</p>
<p>To disable unix extension put following in global section
of smb.conf and restart smb service<span></span><span><em><em><code><br>
unix extensions</code></em><span> </span>=<span> </span><code>no</code></em></span></p><div><div class="h5">

Hi kane,<br>
<br>
I do run IOs using win7 client
with glusterfs3.4 , but I
never compared the
performance with Linux cifs
mount. I don't think we need
to do any special
configuration on Windows side.
I hope your Linux and Windows
client have similar
configuration i.e. RAM, cache,
disk type etc. However I am
curious to know if your setup
uses the vfs plug-in
correctly. We can confirm that
looking at smb.conf entry for
the gluster volume which
should have been created by
"gluster start command"
automatically .<br>
<br>
e.g: entry in smb.conf for one
of volume "smbvol" of mine
looks like below<br>
<br>
[gluster-smbvol]<br>
comment = For samba share of
volume smbvol<br>
vfs objects = glusterfs<br>
glusterfs:volume = smbvol<br>
path = /<br>
read only = no<br>
guest ok = yes<br>
<br>
Kindly copy the entries in
smb.conf for your gluster
volume in this email.<br>
