Make sure xfs_repair can't clear the log by default when it is corrupted.
xfs_repair always and only clear the log when the -L parameter is specified.
This has updated by:
Commit f2053bc ("xfs_repair: don't clear the log by default")
Can you please put more details in commit log? e.g. what's the problem
you want to fix, what's the symptom, etc. I had a hard time
understanding the problems without running the test.

Hi Eryu
xfs_repair without -L option succeeded to repair filesystem at xfs/098 if log is corrupted. However, this feature has been changed by following patch since xfsprogs-dev(4.3.0), we have to use -L option to
repair filesystem if log is corrupted.
Commit f2053bc ("xfs_repair: don't clear the log by default")

xfs/098 will fail to repair filesystem if log is corrupted since xfsprogs-dev(4.3.0), so fix it.

Thanks
Xiao Yang.

The above two redirection updates seem not necessary to me, mount
failure message got redirected to $seqres.full in both cases. Any reason
doing so?

Thanks,

Hi Eryu
if xfs_repair without -L option can succeed to repair filesystem, the second mount will skip.

Thanks
Xiao Yang.
