Hi, I am quite new to ceph and just try to set up a ceph cluster. Initially I used ceph-deploy for this but when I tried to create a BlueStore osd ceph-deploy fails. Next I tried the direct way on one of the OSD-nodes using ceph-volume to create the osd, but this also fails. Below you can see what ceph-volume says. I ensured that there was no left over lvm VG and LV on the disk sdg before I started the osd creation for this disk. The very same error happens also on other disks not just for /dev/sdg. All the disk have 4TB in size and the linux system is Ubuntu 18.04 and finally ceph is installed in version 13.2.4-1bionic from this repo: https://download.ceph.com/debian-mimic. There is a VG and two LV's on the system for the ubuntu system itself that is installed on two separate disks configured as software raid1 and lvm on top of the raid. But I cannot imagine that this might do any harm to cephs osd creation. Does anyone have an idea what might be wrong?
