# ID: zvol_ENOSPC_001_pos
#
# DESCRIPTION:
# A zvol volume will return ENOSPC when the underlying pool runs out of
# space.
#
# STRATEGY:
# 1. Create a pool
# 2. Create a zvol volume
# 3. Create a ufs file system ontop of the zvol
# 4. Mount the ufs file system
# 5. Fill volume until ENOSPC is returned
#
# TESTABILITY: explicit
#
# TEST_AUTOMATION_LEVEL: automated
#
# CODING_STATUS: COMPLETED (2005-07-04)
