Hi, seems you have already done some reading, so here is only very brief comments which might help you understand things for second reading:
If you don't have an NFS filesystem with (at least) 15*10GB=150GB, you can't do the NFS installation. In your case, you want to copy the images to the local disks of the worker nodes, so you want "Non-Shared - SSH" described on: http://opennebula.org/documentation:rel2.2:sm Yours, Steffen ________________________________ From: users-boun...@lists.opennebula.org [users-boun...@lists.opennebula.org] on behalf of Anders Branderud [anders.brande...@gmail.com] Sent: 13 May 2011 15:17 To: users@lists.opennebula.org Subject: [one-users] Open Nebula, NFS and requirements of disk space? Hello! I have read this information about required disk space for installing Open Nebula: "Example: A 64 core cluster will typically run around 80VMs, each VM will require an average of 10GB of disk space. So you will need ~800GB for /srv/cloud/one, you will also want to store 10-15 master images so ~200GB for /srv/cloud/images. A 1TB /srv/cloud will be enough for this ex" Here is my question: I have 16 computers and each of them has a harddrive of 36 GB each. Will the disk space suffice for this? [This is how I plan to configure the system:] There are only two master images (i.e. approx. 20 GB). There can be between 1 and 15 virtual machines. The virtual machines run on the worker nodes of Open Nebula. The master images are not cloned and they are not stored when the regular user is finished with his/her session. I understand that it won't work if this is necessary: "/srv/cloud/one, will hold the OpenNebula installation and the clones for the running VMs". How do I configure the system to not clone the running VM's, but to only to run them on the worker nodes? If the disk space suffices, then how do I configure the system to accomplish the above requirements? I plan to install the system on CentOS, using the express installation (for NFS) provided on Open Nebula's website.
