# DESCRIPTION:
#	ENOSPC is returned on pools with large physical block size and small
#	recordsize.
#
# STRATEGY:
#	1. Create a pool with property ashift=13 (8K block size)
#	2. Set property recordsize=512 and copies=3 on the root dataset
#	3. Write a file until the file system is full
#	4. Verify the return code is ENOSPC
