This is expected. ceph-volume with BlueStore does not use any filesystem
at all, but rather stores its metadata in LVM tags. When the OSDs are
activated, a ramdisk (tmpfs) is mounted on /var/lib/ceph/osd/* and then
the minimal files to start a BlueStore OSD are created from the LVM tags.

The dev-sdh1.device errors sound like systemd is still trying to mount
the old OSDs, which used disk partitions. Look in /etc/fstab and in
/etc/systemd/system for any references to those filesystems and get rid
of them. /dev/sdh1 and company no longer exist, and nothing should
reference them.
