NFS network share, I can mount it but not write to it although I am owner

[pastic]

I am grappling with this since several hours, but I think I am out of ideas.
I have a NAS with an NFS share 'dev' that I am trying to mount to /media/freenas/dev and getting write access to my local user. My user 'peter' thus needs to be owner of the mounted files and folders. 'peter' is already owner recursively of dev on the NAS, and locally /media/freenas/dev is owned by my 'peter'.
I have put this in fstab:

Code: Select all

10.0.0.50:/mnt/TANK/dev    /media/freenas/dev    nfs    rw,noauto,user    0 0

and with this 'peter' can mount the share but 'peter cannot write to it. When it is mounted the owner locally changes from 'peter' to '1002', which is the userid of 'peter' on the NAS.

When I mount smb shares in /media/freenas/ I can specify uid=peter,username=peter,userpass=mypass, but this is not possible with NFS apparently.

Actually, I can't even mount it in /home/peter/ and have write access. I thought 'rw' was supposed to take care of that?
