By the way, I intend to install jewel version throught “rpm” command, and I already have a user “ceph” on the target machine, is there any problem if I do “systemctl start ceph.target” after the installation of jewel version? 发件人: ceph-users [mailto:ceph-users-bounces@xxxxxxxxxxxxxx] 代表 许雪寒 发送时间: 2017年6月20日 10:35 收件人: ceph-users@xxxxxxxxxxxxxx 主题: Question about upgrading ceph clusters from Hammer to Jewel Hi, everyone. I intend to upgrade one of our ceph clusters from Hammer to Jewel, I wonder in what order I should upgrade the MON, OSD and LIBRBD? Is there any problem to have some of these components running Hammer version while others running Jewel version? Do I have to upgrade QEMU as well to adapt to the Jewel version’s LIBRBD? Thank you☺ _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
