Hi,
I am using centos-ci infra for setting up CI for glusterfs (as part of Storage-SIG). And we need to have a proper disk for creating lvms which acts as gluster bricks.
Right now duffy just gives you a machine with everything in root filesystem. This is not optimal for testing glusterfs for many reasons. Is it possible to request duffy to give a machine with small amount of storage for root and rest for our testing? It is Okay for us to wait for few minutes until duffy gives us the machines.
Is there any workaround or any hack that we could do to get this done?
Best Regards, Vishwanath

Actually there is no possibility to do that (lack of available hardware/storage) , and it was discussed here : https://lists.centos.org/pipermail/ci-users/2016-January/000101.html (see the whole thread) , but you can find the following workaround interesting : https://lists.centos.org/pipermail/ci-users/2016-January/000127.html

We should have this working in the near term. The aim is to have another api call to Duffy that allows you to submit your own kickstart, and wait for the machine to redeploy ( it would be 4 to 7 minutes depending on activity ).
The backing disks however, are limited - so you could potentially do a large vg, with only a small chunk allocated, but you wont be able to actually do multiple block devices ( yet ).
The option of having iscsi blocks available for folks to consume has been thrashed out as well, its on the cards, but I dont think we are going to be in a position to get that setup in the next 4 to 8 week period ( basically, this becomes an option once we are all consolidated into the new hosting facility, but have no confirmed date for that yet other than - in the next few months ).

https://github.com/kbsingh/centos-ci-scripts/blob/master/create_looped_disk.... perhaps ? use that to setup some disks... ideally, to not do any performance numbers though :)
