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
$ c
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

Btw, I am using ceph-volume.
I just test ceph-disk. In this case, the ceph-0 folder is mounted from
/dev/sdb1.
So tmpfs only happens when using ceph-volume? how it works?

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`,
`whoami`
