​​ Yes, I am using ceph-volume. And i found where the keyring comes from. bluestore will save all the information at the starting of disk (BDEV_LABEL_BLOCK_SIZE=4096) this area is used for saving labels, including keyring, whoami etc. these can be read through ceph-bluestore-tool show-lable $

Likely the differences you're seeing of /dev/sdb1 and tmpfs have to do with how ceph-disk vs ceph-volume manage the OSDs and what their defaults are. ceph-disk will create partitions on devices while ceph-volume configures LVM on the block device. Also with bluestore you do not have a standard

I am testing ceph Luminous, the environment is - centos 7.4 - ceph luminous ( ceph offical repo) - ceph-deploy 2.0 - bluestore + separate wal and db I found the ceph osd folder `/var/lib/ceph/osd/ceph-0` is mounted from tmpfs. But where the files in that folder come from? like `keyring`,
