I noticed while testing a different mkfs option that btrfs/029 was failing because it was getting the extra output from our mkfs.btrfs. After I fixed that I was still failing because my version of cp will spit out the source and destination files, not just the destination file. So redirect _scratch_mkfs to /dev/null like everybody does and make the golden output just expect to see "cp failed" instead of the cp specific output.

# 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.
