Hi Guys,

I am new to ProxMox and just figuring it all out.

When I try to add a folder on our NAS I am getting the following error

[FONT=tahoma, arial, verdana, sans-serif]"export: invalid format - value does not look like a valid absolute path"[/FONT]

[FONT=tahoma, arial, verdana, sans-serif]

The NAS is configured in the following manner.

ip : 192.168.1.175
Share to use as ISO store : [/FONT]\\192.168.1.175\Volume_1\Main Share\Software\Operating System\ProxMoxNFS

In ProxMox I added the store with the following details
ID : SataNas
Server : 192.168.1.175
Export : \Volume_1\Main Share\Software\Operating System\ProxMoxNFS
Content : Images
Nodes : All
Enable : Ticked
Max Backups : 1


Any help is gratefully received. Thanks in advance guys :D

Please stop to add 'Bump' messages - that is totally useless.

Try to use '/' instead of '\':

Export : /Volume_1/Main Share/Software/Operating System/ProxMoxNFS

Also, there is a 'space' in that path ('Operating System') - AFAIK you need to remove that.

Hi Dietmar,

It has now accepted the format, however, when I click any of the shares in ProxMox I get a message saying "Loading" which lasts for a few moments, then switches to "Communication Failure".

Any ideas?

Thanks

Hi,
do you have the right permissions set for the pve-nodes?
On the CLI you can see the mounted device?
Do pve create a subdirectory-structure (depends on what you have selected to use the storage (template, VM-disks, backup)) like images,dump,template...?
Code: 
mount
ls -lsa /path/of/mounted/nfs-share

Re: NFS Error "export: invalid format - value does not look like a valid absolute pat

Hi,

How can i tell if the permissions are correct on the pve-nodes?

How do I check if I can see the mounted device on the CLI?

The PVE has not created a sub directory structure.

What is this code for ?
Code: 
mountls -lsa /path/of/mounted/nfs-share

Hi,
log in the console (or better for copy/paste via ssh) as root and type the following commands
[code]
mount
cat /etc/pve/storage.cfg
if you post the result, i can give further hints.

Hi,
two things:
First in your case you need only one share - pve do the rest for you with different subdirs (template/iso, dump, images...).
Second your export contains a space - if you can't disable the space, you must mascerade the space - try the whole export in ":
Code: 
nfs: SATA_NAS
        path /mnt/pve/SATA_NAS
        server 192.168.1.175
        export "/Volume_1/Main Share/Software/Operating_System/ProxMoxNFS"
        options vers=3
        content vztmpl,rootdir,images,iso
        maxfiles 1
mount shows, that ther isn't mounted anything from the nas.

Re: NFS Error "export: invalid format - value does not look like a valid absolute pat

Hey, thanks for all the heads up.

I made your changes, I cant mascerade the space with "" as that produces an error.

I still get "Loading" for ages then "Communication Failure" when i try to click the content tab on the NFS :/

When I do mount now I get

/dev/mapper/pve-root on / type ext3 (rw,errors=remount-ro)tmpfs on /lib/init/rw type tmpfs (rw,nosuid,mode=0755)
proc on /proc type proc (rw,noexec,nosuid,nodev)

Hi,
what error do you get, if you mount the NAS on the console?
Code: 
mount 192.168.1.175:/Volume_1/Main_Share/Software/Operating_System/ProxMoxNFS /mnt/pve/SATA_NAS

Re: NFS Error "export: invalid format - value does not look like a valid absolute pat

Hi Udo,

When i did "
mount 192.168.1.175:/Volume_1/Main_Share/Software/Operating_System/ProxMoxNFS /mnt/pve/SATA_NAS" the console jumped to a new line and waited for quite some time (around 3-4 mins), eventually it produces the following error
​
mount.nfs: Connection timed out

The command
showmount --all 192.168.1.175 Produces the following


​
clnt_create: RPC: Port mapper failure - RPC: Unable to receive



The command
showmount --exports 192.168.1.175 produces the following
​

clnt_create: RPC: Port mapper failure - RPC: Unable to receive



Thanks for the assistance so far, i really appreciate it.

Hi,
this shows that your NAS don't speak to your pve-host. Perhaps you must enable the pve-host for nfs-access on the NAS? BTW. you share the directory as nfs and not as smb/cifs?

Or do you have an firewall between pve-host and NAS?

I can't respond further this evening - it's late i must go sleep.

Re: NFS Error "export: invalid format - value does not look like a valid absolute pat

Hi Udo, Have a good sleep :)

How can i enable the pve-host for nfs-access? Every other system on my network can access the NAS without problem, windows, CentOS and MAC.

If I add it as a directory, I can use it on all Nodes, however, nothing is actually written to the nas, and the templates I download are only viewable on the node I download them on.

Help.. Lol

Thanks again for your time today Udo. Good Night.

Hi,
the pve-host don't need to be enabled for nfs-access. But normaly you must define, which host (or networks) has access to the share.
What is the output of "mount" and "showmount --exports 192.168.1.175" on the CentOS-System if you have mounted an filesystem from the NAS?
