I'm testing an upgrade to Nautilus on a development cluster and the command "ceph device ls" is returning an empty list. # ceph device ls DEVICE HOST:DEV DAEMONS LIFE EXPECTANCY # I have walked through the luminous upgrade documentation under https://docs.ceph.com/docs/master/releases/nautilus/#upgrading-from-mimic-or-luminous but I don't see anything pertaining to "activating" device support under Nautilus. The devices are visible to ceph-volume on the OSS nodes. ie: osdev-stor1 ~]# ceph-volume lvm list ====== osd.0 ======= [block] /dev/ceph-f5eb16ec-7074-477b-8f83-ce87c5f74fa3/osd-block-c1de464f-d838-4558-ba75-1c268e538d6b block device /dev/ceph-f5eb16ec-7074-477b-8f83-ce87c5f74fa3/osd-block-c1de464f-d838-4558-ba75-1c268e538d6b block uuid dlbIm6-H5za-001b-C3mQ-EGks-yoed-zoQpoo <snip> devices /dev/sdb ====== osd.2 ======= [block] /dev/ceph-37145a74-6b2b-4519-b72e-2defe11732aa/osd-block-e06c513b-5af3-4bf6-927f-1f0142c59e8a block device /dev/ceph-37145a74-6b2b-4519-b72e-2defe11732aa/osd-block-e06c513b-5af3-4bf6-927f-1f0142c59e8a block uuid egdvpm-3bXx-xmNO-ACzp-nxax-Wka2-81rfNT <snip> devices /dev/sdc Is there a step I missed?
