# DESCRIPTION:
# Doing a 'mv' of a large amount of files between two directories
# within a zfs filesystem works without errors.
#
# STRATEGY:
#
# 1. create a pool and a zfs filesystem
# 2. create two directories within the filesystem
# 3. create a large number of files within a directory
# 4. Move files from one directory to another and back again
# 5. validate file number
# 6. increase the number of files to $MVNUMFILES + $MVNUMINCR
# 7. repeat steps 3,4,5,6 above
# 8. verify the data integrity
