When you are using NFS encoding on ZFS Storage Appliance, inappropriate DNS settings cause NFS not being able to convert the path names into the expected encoding.

Symptoms

As a part of NFS service functionality, users can set encoding to specify what character code set the path names are using.

However, in a DNS-less environment, the NFS code fails to call the conversion code and may result in garbled path names.

Cause

In mountd.c and nfs_cmd.c code, there are places we are calling DNS lookup. The call to DNS lookup has now been changed so that it works even if a DNS server is not present.

Before the modifications, the failure of the DNS function resulted in NFS code not calling 'kiconv' or a kernel module to process the encoding, to convert the path name.

Solution

Upgrade to Appliance Firmware Release 2013.1.1.5 or later.
