# XFS v5 supers carry an LSN in various on-disk structures to track when
|
|
# associated metadata was last written to disk. These metadata LSNs must always
|
|
# be behind the current LSN as dictated by the log to ensure log recovery
|
|
# correctness after a potential crash. This test uses xfs_db to intentionally
|
|
# put the current LSN behind metadata LSNs and verifies that the kernel and
|
|
# xfs_repair detect the problem.
