[NFS-Ganesha-Support] Re: Initial testing with ESXi 6.7

8 Jan 2021

      What files actually exist in the /nfs file system? Those errors about referrals are because Ganesha is trying to check if a file is supposed to be a referral, but it can't get attributes for the file. Turning on some debug would help, add this to your config:

LOG {
    COMPONENTS {
        FSAL = FULL_DEBUG;
    }
}

And either re-start or issue a SIGHUP. We can get a better idea of what is going on.

Subject: [NFS-Ganesha-Support] Initial testing with ESXi 6.7
Hello All,
I am attempting to get nfs-ganesha 3.0.3 under Ubuntu 20.04 working with
ESXi.  While I can successfully mount the NFS export I receive regular errors
while performing any kind of file work through ESXi.  The volume /vdb is just raw
formatted with XFS and the environment is completely virtual.  Any suggestions
for debugging this farther as this is my first time trying out this configuration.
