I am also receiving this same error. I am trying to move the location to a Lacie 5big NAS.

Inbroker - did you only make these changes:
“[FONT=sans-serif][COLOR=#000000]Edit the storage node definition with the IP address of your NFS server and set the image location to the path on the nfs server. Make sure it has a file called .mntcheck in the root of the share, a directory called dev and a .mntcheck file in the dev folder.” or did you also have to edit the config.php file? I am getting the same error trying to save the images to a Lacie 5big NAS. [/COLOR][/FONT][quote=“Inbroker, post: 1020, member: 398”]Hi Nikolai,
thanks for your reply. Actually in my case the solution was even simpler since i didn’t have to mess up with iSCSI but just an external NFS server. So, another classic case of RTFW as described here [url]http://fogproject.org/wiki/index.php?title=FOGUserGuide#Separate_NFS_Server[/url].
Don’t know why but my mind has stuck in the idea that the /images folder was some kind of a magical folder required by Fog. I just pointed the image directory to the NFS share and it worked fine.

Thanks for your help.[/quote]
