# DESCRIPTION:
# Verify that ZFS volume property "volmode" works as intended.
#
# STRATEGY:
# 1. Verify "volmode" property does not accept invalid values
# 2. Verify "volmode=none" hides ZVOL device nodes
# 3. Verify "volmode=full" exposes a fully functional device
# 4. Verify "volmode=dev" hides partition info on the device
# 5. Verify "volmode=default" behaves accordingly to "volmode" module parameter
# 6. Verify "volmode" property is inherited correctly
# 7. Verify "volmode" behaves correctly at import time
# 8. Verify "volmode" behaves accordingly to zvol_inhibit_dev (Linux only)
#
# NOTE: changing volmode may need to remove minors, which could be open, so call
#       udev_wait() before we "zfs set volmode=<value>".
