XFS has an issue where superblock counters may not be properly synced when recovery occurs via a read-only mount. This causes the filesystem to become inconsistent after unmount. To cover this test case, update generic/388 to switch between read-only and read-write mounts to perform log recovery. Signed-off-by: Brian Foster <bfoster@redhat.com> Reviewed-by: Darrick J.

# Test XFS log recovery ordering on v5 superblock filesystems. XFS had a problem
|
|
# where it would incorrectly replay older modifications from the log over more
|
|
# recent versions of metadata due to failure to update metadata LSNs during log
|
|
# recovery. This could result in false positive reports of corruption during log
|
|
# recovery and permanent mount failure.
|
|
#
|
|
# To test this situation, run frequent shutdowns immediately after log recovery.
|
|
# Ensure that log recovery does not recover stale modifications and cause
|
|
# spurious corruption reports and/or mount failures.
