<br>
I recently got some help regarding removing an OSS/OST from the file system. Last thing I did was to permanently remove it with (on the MDS):<br>
<pre wrap=""><big>lctl conf_param ost_name.osc.active=0</big></pre>
This all seems to be working, and on the clients, the command<br>
<br>
<pre wrap=""><big>lctl dl</big></pre>
<br>
indicates the OSS/OST is inactive. However, after a reboot of the clients the same command no longer indicates the removed OSS/OST to be inactive. Besides, the command<br>
<br>
<pre wrap="">df
</pre>
Takes almost 2 minutes to complete.<br>
<br>
I'm probably doing something really stupid here, and would be happy if someone could tell me what it is ;-)<br>
<br>
Running 2.5.3.<br>
<br>
