# Description:
# Verify resumability of a full ZFS send/receive with the source filesystem
# unmounted.
#
# Strategy:
# 1. Destroy the filesystem for the receive
# 2. Unmount the source filesystem
# 3. Start a full ZFS send, redirect output to a file
# 4. Mess up the contents of the stream state file on disk
# 5. Try ZFS receive, which should fail with a checksum mismatch error
# 6. ZFS send to the stream state file again using the receive_resume_token
# 7. ZFS receive and verify the receive completes successfully
