Hi All, For all those who have been hit by the bug in Ubuntu where update-grub causes your OSD's to crash out when it probes the partition, a fixed package has been released to xenial-proposed which fixes the problem. I have installed and confirm it fixes the problem. https://launchpad.net/ubuntu/+source/os-prober/1.70ubuntu3.1 Nick _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
