Description

Looking at logs for sanity test 205b, for example at https://testing.whamcloud.com/sub_tests/a18f122e-e464-43be-9472-da6588a10be6, we see an error when trying to clear job_stats

== sanity test 205b: Verify job stats jobid and output format ======================================== 10:42:51 (1622198571)
error: set_param: param_path 'mdt/*/job_stats': No such file or directory

Looking at test 205b, we see that we are trying to clear the job_stats on the client with

17642 test_205b() {
17643         job_stats="mdt.*.job_stats"
17644         $LCTL set_param $job_stats=clear

If we want to clear the local statistics, the Lustre manual says to run

Clear statistics for all jobs on the local node:

# lctl set_param obdfilter.*.job_stats=clear

If we want to clear all statistics, then we should run the command on line 17644 on the MDS.
