This I don't really know where it comes from. I think at a certain point I ran "ceph osd crush tunables optimal", and it probably added "vary_r", but then I run "ceph osd crush tunables firefly" and it didn't remove it... is it normal? > If you want older kernels to talk to the cluster, you need to avoid the > new tunables and features! Well, as I said, I'm not a ceph expert, I didn't even know I enabled features the kernel of the distribution did not support. I guess the problem is that I am using packages from the ceph.com repo, while the kernel comes from ubuntu. However, it's at least curious that when I was running firefly from ubuntu repositories I could create an EC pool, but the kernel was not compatible with EC2 pools... .a. -- antonio.messina@xxxxxxxxxxx +41 (0)44 635 42 22 antonio.s.messina@xxxxxxxxx S3IT: Service and Support for Science IT http://www.s3it.uzh.ch/ University of Zurich Winterthurerstrasse 190 CH-8057 Zurich Switzerland _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
