Symptoms

When adding a NFS exception to a share it disappears once applied in the Browser User Interface(BUI) or reports the following error from the Command Line Interface(CLI):

error: An unanticipated system error occurred: cannot set property for
'<pool_name>/local/<project_name>/<share_name>': invalid property value: cannot mix "*"
with other values: <NFS_exception>

Changes

In this example, I am attempting to define the client FQDN 'client.domain.tld', as having read and write permissions for the share 'TestShare' in the 'default' project:

ZFSSA:> shares select default select TestShare
ZFSSA:shares default/TestShare> get sharenfs
sharenfs = sec=sys,rw
ZFSSA:shares default/TestShare> set sharenfs="sec=sys,rw,rw=client.domain.tld"
sharenfs = sec=sys,rw,rw=client.domain.tld (uncommitted)
ZFSSA:shares default/TestShare> commit
error: An unanticipated system error occurred: cannot set property for
'pool-1/local/default/TestShare': invalid property value: cannot mix "*"
with other values: rw=*:client.domain.tld

This may be due to transient failure, or a software defect. If this problem
persists, contact your service provider.

The similar operation - in the BUI - results in the exception being added disappearing after the change is applied.

Cause

The ZFS Storage Appliance does not support explicitly defining NFS exceptions that duplicate the default permissions.

ie. The default share mode is read/write so you cannot define some specific host, domain or subnet as share mode: read/write.

Solution

Only add exceptions that differ from the default of the share.
