#
# DESCRIPTION:
# 'zpool create' will fail in the following cases:
# existent pool; device is part of an active pool; nested virtual devices;
# differently sized devices without -f option; device being currently
# mounted; devices in /etc/vfstab; specified as the dedicated dump device.
#
# STRATEGY:
# 1. Create case scenarios
# 2. For each scenario, try to create a new pool with the virtual devices
# 3. Verify the creation is failed.
