So the test always fails due to a mismatch with this expected golden output:
-Label: none uuid: <UUID>
+Label: none uuid: <UUID>
Total devices <NUM> FS bytes used <SIZE>
devid <DEVID> size <SIZE> used <SIZE> path SCRATCH_DEV
devid <DEVID> size <SIZE> used <SIZE> path /dev/mapper/error-test
The extra space after "uuid:" comes from _filter_uuid:
sed -e "s/\(uuid[ :=]\+\) *[0-9a-f-][0-9a-f-]*/\1 <UUID>/ig"
Which gets \1 with the string "uuid: " and then does "uuid: " + " " + "<UUID>".
We need to either to fix the golden output here or _filter_uuid (and
make sure it doesn't break any other tests using it directly or
indirectly such as yours).
commit a092363bbdfa6cc6e44353136bae9d3aa81baae2 (PATCH 3/3 V6] xfs: test
changing UUID on V5 superblock) caused the regression. btrfs/006 is
affected as well.
Thanks
