Hello, Fellow Gluster Users<br>
<br>
I am testing writing file with 'dd' from FUSE client on Centos6 and<br>
Centos5. Command syntax is i have used is:<br>
<br>
/bin/dd if=/dev/zero of=/data/gluster/file bs=20M count=1 oflag=direct<br>
When I run it on Centos6 Client, I am receiving results as expected:<br>
<br>
1+0 records in<br>
1+0 records out<br>
20971520 bytes (21 MB) copied, 0.125189 s, 168 MB/s<br>
<br>
However, when I run the same command on CentOS5.9 I cant create a file.<br>
<br>
/bin/dd: opening `/data/gluster/file': Invalid argument<br>

FUSE kernel module in CentOS 5 does lack support for O_DIRECT. By dropping the oflag=direct argument with CentOS 5, the write should go through.<span class="HOEnZb"><font color="#888888"><br>
