Hi, dear developers of Proxmox!

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

Does your storage support NFS v3 ?

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.

nano /etc/pve/storage.cfg

...
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:

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:

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

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

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:

root@blade1:/etc/pve# vi storage.cfg

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

cat /proc/mounts:

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 have a problem to connect the NAS to my Proxmox server, the issue is that I can not turn on the NAS server to access virtual machines. View image: http://ssmaker.ru/6d047538/

 

[debi@n]

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!

 

[Inalbis]

ok, I'll try that. Thanks

We hade the same problem and it was the NAS that was the problem. We are using FreeNAS and we had forget to bind the right NIC to the NFS service, see image,

 

[TerraLtech]

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.
