Description

In Lustre-1.8 or former releases, the user identity information upcall on Lustre MDS side is through the /proc interface:
/proc/fs/lustre/mds/

{mdsname}

/group_upcall

But for Lustre-2.x, such interface has been replaced (since Lustre-2.0 release) by: /proc/fs/lustre/mdt/

{mdtname}

/identity_upcall

Related mkfs/lctl parameters are changed also. These information is only partly updated in Lustre-2.x manual (section 33.1), should be fixed.

All the "group_upcall" in the manual should be replaced with "identity_upcall", not only for the section "33.1. User/Group Cache Upcall", but also for all the manual parts. The others to be updated include:

1) "mds_grp_downcall_data" => "identity_downcall_data"
2) "l_getgroups" => "l_getidentity"
3) "group_info" => "identity_info"
4) In lustre-1.8, "group_upcall"/"group_info" were under /proc/fs/lustre/mds/${mdsname}/
But in lustre-2.x, "identity_upcall"/"identity_info" are under /proc/fs/lustre/mdt/${mdtname}/

Assuming the answer to the question above is 'yes', the following change is available for review:

Do the changes to identity_upcall also mean 'group_info' should be changed to 'identity_info'?
