Description

obdfilter-survey looks for the Lustre version to see if the variable rszmax should be changed

 253 check_record_size() {
 254         [ $(version_code $(get_lustre_version)) -lt $(version_code 2.3.61) ] &&
 255                 rszmax=1024
...

In logs for obdfilter survey, we see an error when trying to check the Lustre version. For example, in the suite_stdout log for https://testing.hpdd.intel.com/test_sets/586ba2cc-3bb7-11e7-b3f6-5254006e85c2, we see

07:44:33:/usr/bin/obdfilter-survey: line 242: ( << 16) | ( << 8) | : syntax error: operand expected (error token is "<< 16) | ( << 8) | ")
07:44:33:/usr/bin/obdfilter-survey: line 254: [: -lt: unary operator expected

We get the version with

 245 get_lustre_version() {
 246         local host=${1:-${unique_hosts[0]}}
 247         remote_shell $host $lctl get_param -n version |
 248                 awk '/^lustre:/ {print $2}'
 249 }

The problem is that the string "lustre" is no longer returned with the lctl call

# lctl get_param -n version
2.9.56_70_g3dad616

The call to 'lctl get_param' should be not to pipe the results to awk.
