It has been zapped prior. I can't see what the actual command you used is, but I am guessing you did something like: ceph-volume lvm prepare --filestore --data /dev/sdb --journal /dev/sdb Which is not possible. There are a few ways you can do this (see: http://docs.ceph.com/docs/master/ceph-volume/lvm/prepare/#filestore ) With a raw device and a pre-created partition (must have a PARTUUID): ceph-volume lvm prepare --data /dev/sdb --journal /dev/sdc1 With LVs: ceph-volume lvm prepare --data vg/my-data --journal vg/my-journal With an LV for data and a partition: ceph-volume lvm prepare --data vg/my-data --journal /dev/sdc1 > > What is going wrong, and how can I fix it? > > Thank you > R > > > _______________________________________________ > 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
