xfs_db requires us to pass in the log device, if any; this can be accomplished via _scratch_xfs_db_options (if we're operating on the scratch device, anyway). However, many of the tests/xfs/ scripts pass only $SCRATCH_DEV directly, so they'll fail if we test with an external log. Fix that by adding a new _scratch_xfs_db helper. Signed-off-by: Darrick J.

# FS QA Test No. 070
|
|
#
|
|
# As part of superblock verification, xfs_repair checks the primary sb and
|
|
# verifies all secondary sb's against the primary. In the event of geometry
|
|
# inconsistency, repair uses a heuristic that tracks the most frequently
|
|
# occurring settings across the set of N (agcount) superblocks.
|
|
#
|
|
# xfs_repair was subject to a bug that disregards this heuristic in the event
|
|
# that the last secondary superblock in the fs is corrupt. The side effect is an
|
|
# unnecessary and potentially time consuming brute force superblock scan.
|
|
#
|
|
# This is a regression test for the aforementioned xfs_repair bug. We
|
|
# intentionally corrupt the last superblock in the fs, run xfs_repair and
|
|
# verify it repairs the fs correctly. We explicitly detect a brute force scan
|
|
# and abort the repair to save time in the failure case.
