This is probably due to the Kernel RBD client not being recent enough. Have you tried upgrading your kernel to a newer version? 3.16 should contain all the relevant features required by Giant. -----Original Message----- From: ceph-users [mailto:ceph-users-bounces@xxxxxxxxxxxxxx] On Behalf Of Antonio Messina Sent: 05 December 2014 09:37 To: Anthony Alba Cc: ceph-users@xxxxxxxxxxxxxx Subject: Re: Giant or Firefly for production On Fri, Dec 5, 2014 at 2:24 AM, Anthony Alba <ascanio.alba7@xxxxxxxxx> wrote: > Hi Cephers, > > Have anyone of you decided to put Giant into production instead of Firefly? This is very interesting to me too: we are going to deploy a large ceph cluster on Ubuntu 14.04 LTS, and so far what I have found is that the rbd module in Ubuntu Trusty doesn't seem compatible with giant: feature set mismatch, my 4a042a42 < server's 2104a042a42, missing 21000000000 I tried with different "ceph osd tunables" but nothing seems to fix the issue However, this cluster will be mainly used for OpenStack, and qemu is able to access the rbd volume, so this might not be a big problem for me. .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 _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
