Bug #25207
Updated by Alfredo Deza over 5 years ago
Hi, I am trying to install the osd on nvme drive. It is not linked to any volume groups. When i tried to use the command "ceph-volume lvm create --data /dev/nvme1n1" on the osd node, i got the following segmentation fault. For testing, on the other server, i created a volume group and the logical volume, used the "ceph-volume lvm create --data ceph_vg_ce2/osd_A", even this gives the segmenatation fault.
