lmtmetric does not work on mds; it is OK checking ost on oss.<br>
<br>
# lmtmetric -m mdt<br>
lmtmetric: error reading lustre MDS uuid from proc: Invalid argument<br>
lmtmetric: mdt metric: Invalid argument<br>
<br>
I suspect it is due to lmtmetric constantly reading /proc/fs/lustre/version and it is now in /sys/...<br>

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