# FS QA Test No. 029
|
|
#
|
|
# Check if creating a sparse copy ("reflink") of a file on btrfs
|
|
# expectedly fails when it's done between different filesystems or
|
|
# different mount points of the same filesystem.
|
|
#
|
|
# For both situations, these actions are executed:
|
|
# - Copy a file with the reflink=auto option.
|
|
# A normal copy should be created.
|
|
# - Copy a file with the reflink=always option. Should result in
|
|
# error.
