It looks like the math is failing because of the use of decimal numbers, even though the test itself is passing.
The test is then trying to use either "virt-what" or "dmidecode" to decide if this is a VM or not. Either or both of the virt-what or dmidecode RPMs needs to be installed for that, but this is secondary to the actual failure.
Not sure why this started failing now. It looks like it has always been failing, but "dmidecode" or "virt-what" were causing the error to be ignored:
Average uncached read: 15.93 Average speedup with OSS cached read: 22.10 = +38.73% Average speedup with ladvise willread: 21.49 = +34.90% /usr/lib64/lustre/tests/sanity.sh: line 19613: [: 11.05: integer expression expected running in VM 'kvm', ignore error sanity test_255a: @@@@@@ IGNORE (env=kvm): Speedup with willread is less than 11.05%, got 21.49%
There likely also needs to be a "dmidecode" package installed on some of the test nodes/images to solve this completely, but it is worthwhile to fix the actual test cases first if this isn't too disruptive.
