Before adding/replacing new OSDs: What version of xfs is preferred by ceph developers/testers now? Time ago I move all to v5 (crc=1,finobt=1), it works, exclude "logbsize=256k,logbufs=8" in 4.4. Now I see, v5 is default mode (xfsprogs & kernel 4.5 at least).
I in doubts: make new OSDs old-style v4 + logbsize=256k,logbufs=8 (and remove v5 crc worloads) - increase linear performance (exclude rm/ls operations), or make current default v5 to other benefits. Are xfs v4 still mainstream for ceph? PS I use too fresh "unstable" Gentoo ~amd64, so don't know some normal distros reality... -- WBR, Dzianis Kahanovich AKA Denis Kaganovich, http://mahatma.bspu.unibel.by/ _______________________________________________ ceph-users mailing list ceph-users@lists.ceph.com http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
