<p class="MsoNormal">Dear Sir:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">How does one use a striped provisioned IOPS EBS volume in a StarCluster-generated cluster? I am not sure what to put in the “config” file.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I launched a single “m2.4xlarge” instance to create a 6-way striped provisioned IOPS EBS volume by first creating six provisioned IOPS volumes, each being 100GB in size and set for using 1000 IOPS, attached each to the “m2.4xlarge” instance,
and striped the ensemble by using the commands:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">sudo mdadm --create /dev/md0 --level=0 --chunk=64 --raid-devices=6 /dev/sdg /dev/sdh /dev/sdi /dev/sdj /dev/sdk /dev/sdl<o:p></o:p></p>
<p class="MsoNormal">sudo yum install -y xfsprogs<o:p></o:p></p>
<p class="MsoNormal">sudo mkdir -p /Work && sudo mkfs.xfs /dev/md0 && sudo mount -t xfs /dev/md0 /Work && sudo chown ec2-user:ec2-user /Work<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">How do I declare the striped volume “Work” in the “config” file? Or should I simply declare these six volumes in my “config” file, and repeat the three commands above once I have started the cluster and I am logged into “master”? Will
the other cluster nodes see “/Work” as a 6-way striped EBS volume?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thank you for any information.<o:p></o:p></p>
