Hello all,
Trivial check: In section 17.2 of the Lustre manual, under major
release upgrades, this is noted as step 14:

> Introduced in Lustre 2.7
> (Optional) If you are upgrading from a release before Lustre 2.7, to 
> enable OST FIDs to also store the OST index (to improve reliability of 
> LFSCK and debug messages), after the OSTs are mounted run once on each 
> OSS:
> oss# lctl set_param osd-ldiskfs.*.osd_index_in_idif=1

We recently went from Lustre 2.5 to 2.8 (on our way to 2.12), and
I would like to add the above setting, now that we have been running
for a few weeks. However, I think it should actually be:

oss# lctl set_param osd-ldiskfs.*.index_in_idif=1

Could someone confirm? I'm far from a pro on all of the various
Lustre variables.

Thanks a lot.
