InstaGENI/ProtoGENI extra disk space
To get extra disk space on your PG/IG VMs you will need to do two steps:
- request it in your rspec
- mount it once your VM is booted
1. RSpec modification
You can specify memory, cores and disk space for your IG/PG VMs using the following rspec tag which is a child of sliver_type:
<emulab:xen cores="2" ram="2048" disk="5"/>
An example of a complete rspec:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?> <rspec generated="2014-03-22T01:53:21.460+01:00" generated_by="Experimental jFed Rspec Editor" type="request" xsi:schemaLocation="http://www.geni.net/resources/rspec/3 http://www.geni.net/resources/rspec/3/request.xsd" xmlns="http://www.geni.net/resources/rspec/3" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:emulab="http://www.protogeni.net/resources/rspec/ext/emulab/1"> <node client_id="node0" component_manager_id="urn:publicid:IDN+wall2.ilabt.iminds.be+authority+cm" exclusive="true"> <sliver_type name="emulab-xen"> <emulab:xen cores="2" ram="2048" disk="5"/> </sliver_type> </node> </rspec>
2. Mount the space
What you have to do is login to the VM after it is reserved and run these commands:
sudo bash /usr/testbed/bin/mkextrafs /mnt exit Then you should see a new device that will look like: /dev/xvda4 7.9G 147M 7.4G 2% /mnt
