Hi, dear developers of Proxmox!

I have a next appears a bug when uploading my ISO files on nfs storage:

And we get error message:

 
Re: Error 500: mount error: mount.nfs: requested NFS version or transport protocol is

Does your storage support NFS v3 ?
 
Re: Error 500: mount error: mount.nfs: requested NFS version or transport protocol is

Sorry, I dont now.
How chek this parametr?
I creating nfs storage on disk, where located Proxmox.
 
Re: Error 500: mount error: mount.nfs: requested NFS version or transport protocol is

in the case your server exports NFSv3, you need to add the following option to the storage definition, see this example.

Code: 
nano /etc/pve/storage.cfg

Code: 
...
nfs: freenas-nfs
        path /mnt/pve/freenas-nfs
        server freenas.proxmox.com
        export /mnt/nfs
[COLOR=#ff0000]        options vers=3[/COLOR]
        content images,iso,vztmpl,rootdir,backup
...

make sure you unmount and remount to apply the new settings (or just reboot your host).

to make sure you got NFS v3, check your mounts:

Code: 
cat /proc/mounts
 
Re: Error 500: mount error: mount.nfs: requested NFS version or transport protocol is

I'm check storage.cfg. NFS v3 enable:

Code: 
nfs: mynfs
        path /mnt/pve/mynfs
        server 10.0.0.5
        export /mnt/nfs
        options vers=3
        content images,iso,vztmpl,rootdir

Please MAKE SURE your nfs server is working and no blocking the access from PVE host.
 
Re: Error 500: mount error: mount.nfs: requested NFS version or transport protocol is

I'm check storage.cfg. NFS v3 is enable:
Code: 
root@blade1:/etc/pve# vi storage.cfg
Code: 
dir: local        path /var/lib/vz        content images,iso,vztmpl,rootdir        maxfiles 0nfs: NETAPP        path /mnt/pve/NETAPP        server na-cluster2.gbi.de        export /vol/vol_test/qtest        options vers=3        content images,iso,vztmpl,backup,rootdir        maxfiles 1
Code: 
cat /proc/mounts:
Code: 
na-cluster2.xy.de:/vol/vol_test/qtest/ /mnt/pve/NETAPP nfs4 rw,relatime,vers=4,rsize=65536,wsize=65536,namlen=255,hard,proto=tcp,port=0,timeo=600,retrans=2,sec=sys,clientaddr=172.16.y.z,minorversion=0,local_lock=none,addr=172.16.x.z 0 0
In Storage.cfg is the option nfsv3 enabled but cat /proc/mounts is nfs4Have anybody a solution for this issue?
 
i think that the problem is on the nas, im working with nas, and i had the same problem, you need create a client with range ip (that you use on proxmox). on Nas.
Good luck! :D
 
The NAS server that I am trying to use is provided by OVH (ovh.com) I don't have any control on the NAS server.
What is weird is that it was working couple of days before, and if I try attaching the same NAS server to another Proxmox instance it works fine.
