We are aware of the problem. I'm going to try and develop a patch to handle the move to /sys/ in the next week or so.

Subject: [lustre-discuss] ltop for lustre 2.10.2 ?
Is there version of ltop working with lustre 2.10.2 ?
lmtmetric does not work on mds; it is OK checking ost on oss.
# lmtmetric -m mdt
lmtmetric: error reading lustre MDS uuid from proc: Invalid argument
lmtmetric: mdt metric: Invalid argument
I suspect it is due to lmtmetric constantly reading /proc/fs/lustre/version and it is now in /sys/...

I'm trying to get ltop working on SLF 7.4 with lustre 2.10.2. No need for lmt & DB.
