Opennebula with NAS storage

Community Support Storage
1

Hello All,

I am new to opennebula, I am trying to setup a lab environment with NAS storage.I am struggling to bringup a VM.Here is my setup

  1. I have installed frontend and did NFS mount /var/lib/one/datastores from NAS storage where I also have some old images
  2. on the node I have NFS /var/lib/one/datastores
  3. Create image using the source from old Windows Server which is located /var/lib/one/datastores/images
  4. Created VM Template and VM

Once you bring up VM it fails with the following error

Check your NFS share permissions. Check if user oneadmin has all the rights on the node.

Thanks Branislav,

I have looked at the permissions here is what I have

lrwxrwxrwx. 1 oneadmin oneadmin 51 Oct 7 2019 /var/lib/one/datastores/100/9/disk.0 -> /var/lib/one/datastores/images/windows2012_ad.qcow2

when I look at the actual file windows2012_ad_qcow2 it is owned by nfsnobody, do you think that is the problem

Yes looks correct. Try to create and remove files and folders on system and images datastores. Try on front end and node.
