22# DESCRIPTION:
23# Verify 'zfs rename' works on a ZVOL already in use as block device
24#
25# STRATEGY:
26# 1. Create a ZVOL
27# 2. Create a filesystem on the ZVOL device and mount it
28# 3. Rename the ZVOL dataset
29# 4. Receive a send stream with the same name as the old ZVOL dataset and verify
30#    we don't trigger any issue like the one reported in #6263
