Trying to create the Block and Block.DB devices for BlueStore. Within the cephadm shell able to run the vgcreate but get the following errors and we cannot see the vg device in /dev so doesn't seem to actually create the vg, but vgs within the cephadm shell shows it, but vgs at the o/s level does not. FYI - SE Linux is disabled. stdout: Physical volume "/dev/sda" successfully created. Not creating system devices file due to existing VGs. stdout: Volume group "ceph-b80b7206-0c2e-4770-9895-51077b1d59d4" successfully created Running command: lvcreate --yes -l 5245439 -n osd-block-b992b707-c77a-412d-9286-3b3ec1d8b3e9 ceph-b80b7206-0c2e-4770-9895-51077b1d59d4 stderr: /dev/ceph-b80b7206-0c2e-4770-9895-51077b1d59d4/osd-block-b992b707-c77a-412d-9286-3b3ec1d8b3e9: not found: device not cleared Aborting.
