Hello everyone.

Proxmox is a great product. We are using it in production now at our office. So far we love it.

I do have a question in regards to NFS usage in Proxmox. Is it possible to use a NFS volume as the primary hard drive for a virtual machine.

Say i run Ubuntu 10.04 virtual machine and assign the cluster master a 40GB nfs volume.

Using Proxmox. Can I force (in any manner) the virtual machine to use the 40 GB nfs volume as its hard drive. Either with IDE or Iscsi interface.

Best Regards

I assume you talk about KVM virtual machines? But a VM needs a block device as root, so that is not possible. Unless you configure the VM to boot from NFS (but that is unrelated to Proxmox VE).
 
Thanks for the info Dietmar. However, can you please advise what is the best method making sure that the virutla images using block devices can have their data persistent.

Any examples are greatly apprecaited.

Sorry about that. I was wondering. If i use local storage for my virtual machines. What methods i can use to persist their respective data.
 
Thanks for the info Dietmar. I have a few questions, please advise what is the best method of resolving the issue.

1. Create 1 Master node. Vmbr0 runs on eht1 which is 1 Gbps. Eth0 is 100 mbps.

2. Have two slave nodes that connect over the 1 Gbps network to the master.

3. First issue: How to properly setup Vlans so that i can isolate compute vm's for each of my company's departments.

4. I have a Glusterfs 3.2 NAS setup at our location. Was hoping somehow to run all the vm's via that storage environment. What can you recommend i use instead of local storage. DRBD sounds very complex. Can you recommend any opensource ISCSI app that is active/active.

5. Can i use glusterfs to store all the vm backups etc.

6. Can Promox setup a cronjob of backing up vm data live in real time at given intervals without impacting the vm in question.

7. Our slave nodes have two nic cards. so can i run multiple departments on those two cards without each department looking at the others.

Your help is always greatly appreciated.
