FreeNAS NFS share shows zero disk space available on my cluster

[Matthias Looss]

I am a fairly new PROXMOX and I have so far managed to create a 4 node cluster. Ran into a problem here and there, but reading through this forum was very helpful kept me going, until now.

We just purchased a FreeNAS miniXL and will use it for backups via NFS. I am able to create the NFS storage in my data center, but it shows up with zero disk space, when it should show at least 20 TiB, which is the size shown on the dataset in FreeNAS. I have searched for answer but found none, so it is time to ask for help on this issue. When I mount this NFS on my laptop, it lists 24 TB as available.

I am running Proxmox Virtual Environment 4.2-17/e1400248 and I also purchased the basic support subscriptions, but before using up one of my limited support requests I wanted to see if someone can help.

Thanks in advance for any guidance.

Have you given access to all of your proxmox nodes to the NFS share on FreeNAS?

Well, once again I figured it out. PROXMOX root user does not have write access to the NFS share unless you use the Maproot User option in FreeNAS to map it to root. You need to go to the Advanced tab to see this option on FreeNAS.
