NFS4 UID/GID translation problem
 

I'm setting up a NFS4 server/client setup, and am having problems with UID/GIDs, ownership, and ultimately, permissions.

I can mount the export and can view the files. However, I cannot write to the files. When I do a long listing, it shows unusual owning user, owning group info - it shows a long hash of numbers as the owner, and a long hash of numbers as the group. This isn't what the host server shows as the ownership locally.

I know it isn't the client, because I mounted it locally (on the same box the export is housed on), and it does the same thing.

Here is my export:
/data *(rw,wdelay,insecure,sync,fsid=0,no_subtree_check)

Here is my mount command:
mount -t nfs4 10.0.0.12:/ /media/nfs4

How do I fix this problem?

I dont know is it me or.....
I see you have exported the /data dir and are trying to mount the / dir.

is that correct?

I am exporting /data on the server and mounting it on the client. The syntax (/data vs /) is correct because of the pseudofilesystem features of NFS4 (syntax varies from NFS3).

I just don't know why the ownership isn't coming across the mount.
