[lustre-discuss] Missing lfsck_namespace, lfsck_layout

I have started an lfsck on a 12.2.5-MDT.
'lctl lfsck_query' tells me that it is doing layout repairs ('layout_repaired:' is increasing): very good.

However, there is no such thing as 'mdd.FSNAME-MDT_target.lfsck_layout' (which, according to the manual, I should query with lctl get_param).

There is also no 'mdd. FSNAME-MDT_target.lfsck_namespace'

I have checked /sys/fs/lustre/mdd, where the only lfsck-related entries are 'lfsck_async_windows' and 'lfsck_speed_limit'

And nothing of the like can be found anywhere under /proc/fs/lustre or /sys/fs/lustre.

Finally I repeated this on a test system (Lustre 2.12.6) which I have set up fairly recently, therefor I still do remember not deveating at all from 
the defaults.
-> no lfsck_namespace, no lfsck_layout

Just an error in the manual?
