Hi Rhian, not sure if you fond an answer already.
I believe in luminous and mimic it is only possible to extract compression information on osd device level. According to the recent announcement of nautilus, this seems to get better in the future. If you want to check if anything is compressed, you need to find a data-OSD that's in a data pool of your cepf fs. On this OSD you can extract low-level information, including compression statistics. You find details in this conversation: https://www.mail-archive.com/ceph-users@lists.ceph.com/msg49339.html . Hope that helps, ================= Frank Schilder AIT Risø Campus Bygning 109, rum S14 ________________________________________ From: ceph-users <ceph-users-boun...@lists.ceph.com> on behalf of Rhian Resnick <xan...@sepiidae.com> Sent: 16 November 2018 16:58:04 To: ceph-users@lists.ceph.com Subject: [ceph-users] Checking cephfs compression is working How do you confirm that cephfs files and rados objects are being compressed? I don't see how in the docs. _______________________________________________ ceph-users mailing list ceph-users@lists.ceph.com http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
