Debian's bluestore *rocksdb* does not support neither fast CRC nor compression
from osd logs:

I use Debian 9.3 and Ceph Luminous 12.2.2

1. Characteristics of build machine MUST NOT affect builds. i.e. we should strictly override ./configure options which are detected by testing current processor (and current Linux kernel) features.
2. What about compression ? It does not depend on SSE, right ?

Yeah, I agree. Is there a build log from the debian build farm?
The packages we build upstream do appear to have this support, so something is changing the d/* files downstream or something in the environment is not getting overriden.
Hmm, can you confirm that an upstream v12.2.1 package from http://download.ceph.com/debian-luminous/ for stretch or jessie does have the support correctly compiled in?

- Status changed from Need More Info to In Progress
The build args are all coming from ceph.spec.in or debian/rules, and should match up with the builds you see in shaman, e.g. https://jenkins.ceph.com/job/ceph-dev-build/ARCH=x86_64,AVAILABLE_ARCH=x86_64,AVAILABLE_DIST=centos7,DIST=centos7,MACHINE_SIZE=huge/14921/consoleText
You might want to check with Kefu, who looked at this a while back. See http://tracker.ceph.com/issues/21603 and 318189465d1fc034ba8a6db7e981859eca2f10b2
