I tried also using Lustre 1.6.7.2 with the official kernels and it works always in the same way: the first joined server honours the quota denying writing when quota is reached while the second server does allow writing from the same user and from the same client. <div>

Hi Nirmal,<br>
<br>
I've tried with both: " 2.6.18-128.1.6.el5_lustre.1.8.0.1smp x86_64" and "2.6.22.14 x86_64" clients.<br>
<br>
The results is the same.<br>
<br>
Cheers,<br>
Giacinto<br>

I have the quota working on one of our cluster while I am trying to<br>
figure out what is wrong with the second cluster.<br>
<br>
The cluster where I have quota working, the Lustre servers are running<br>
2.6.18-128.1.6.el5_lustre.1.8.0.1smp kernel and the Lustre clients run<br>
on RHEL5.3 distro with the 2.6.18-128.1.10.el5 kernel + Lustre patchless<br>
client version 1.8.0.1.<br>
<br>
The other cluster that I have the same problem that you are facing, the<br>
lustre servers are running 2.6.18-92.1.17.el5_lustre.1.6.7.1smp and the<br>
clients run on RHEL4.4 with 2.6.21 <a href="http://kernel.org" target="_blank">kernel.org</a> kernel + Lustre patchless<br>
clients version 1.6.7.<br>
<br>
The quota problem seems to be related to the kernel on the Client side.<br>
I guess that there is no 64-bit quota support in the 2.6.21 kernel?<br>
<br>
What configuration do you have on the client side? I would be curious to<br>
see if the quota works fine with the 2.6.18-128.1.10.el5 kernel on your<br>
clients.<br>
<br>
