Hi folks,<br>
<br>
I?m running a big cluster of 80 servers. The master is a running server.<br>
When the jobs are ending, I start to remove the idle nodes.<br>
The process of remove nodes from starcluster is taking about 40 minutes per<br>
node. It takes a while when it reaches:<br>
>>> Removing node022 from known_hosts files<br>
>>> Removing node022 from /etc/hosts<br>
<br>
Any hints for speeding up this?<br>
<br>
All best,<br>
<br>
Sergio<br>
