3PAR File Persona NFSv4
Hi,
I am facing a problem with 3PAR File Persona. On the 3PAR side, NFSv4 domain name is set, and on the client the idmapd service is configured correctly. When i mount the file share on the client with NFSv4.0, the files owned by "root" user are displayed as "nobody", but the files owned by other users are displayed correctly. Looks like the "root" user is not getting mapped from 3PAR to client with NFSv4, but all other users are getting mapped.
Can someone please suggest how to solve this issue.
File Persona version is 1.5.4, and the client is RHEL7.4.
Thanks - Shashi Kanth.

Re: 3PAR File Persona NFSv4
What exports-options are used at the FilePersona Server ?
Did you set "no_root_squash" ?
Can you provide the "showfshare nfs -d <nfs-share-name>" output, of the share that is been mounted?
Can you provide the "showfs -auth" output ?
Is the FilePersona node also bound to an Active Directory server ?

Re: 3PAR File Persona NFSv4
read all these documents, but did not found any clue. This is a very basic functionality what customers expects to work with any NAS solution.

Re: 3PAR File Persona NFSv4
The export information looks good.
Are both NFS-client and the FilePersona server in the same NFSv4mapid-domain ?
This is a requirement for correct UID/GID mapping in NFSv4. If the server can´t match the user, it will automatically treat it as user nfsnobody.
At the cli, run "showfs -idmap".
If the output is "No NFSv4 domain is configured", then that´s most likly your problem.
To set/configure the domain in FilePersona run "setfs idmap <your-nfsv4-domain>
You can name the domain as whatever you want. e.g. "NFSv4.testdomain" or your DNS-domain.
The same setting need to be done at the NFSv4-client.
On a Linux system the configuration file is /etc/idmapd.conf.
The default NFSv4mapid-domain is usually the DNS-domain. If NFS-client and the FP-server are in the same DNS domain, then i recommend that you use this as your NFSv4mapid-domain.
If client and server are in different DNS-domains, then you will need to set a uniq one, both at NFS client and NFS-server.
Note that you may need to restart/start the idmapd-service on the client, when changing the config.
If this does not fix the problem, then please engage your HPE-support.
Hope that helps.

Re: 3PAR File Persona NFSv4
the domain is set correctly, on both File Persona and on the client.
except root user, every other normal users are getting mapped from File Persona to the NFSv4 client. The problem is only with the root user is not getting mapped for NFSv4 clients.
% showfs -idmap
NFSv4 domain name: btp.swinfra.net
# grep Domain /etc/idmapd.conf
Domain = btp.swinfra.net

Since the setup seems to be correct, please open a support-ticket.
