21# DESCRIPTION:
22#
23# The use of refreservation=auto on a filesystem does not change the
24# refreservation and results in an error.
25#
26# STRATEGY:
27# 1) Create a filesystem
28# 2) Verify that zfs set refreservation=auto fails without changing
29# refreservation from none.
30# 3) Set refreservation to a valid value.
31# 4) Verify that zfs set refreservation=auto fails without changing
32# refreservation from the previous value.
