Looks like I found the answer. The preparation was not the proper way. I
found valuable information in ceph-disk prepare --help page; the cluster
oprating better way:
NAMEMAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:00 931,5G 0 disk
├─sda18:10 476M 0 part
├─sda28:2
sudo df -h:
udev3,9G 0 3,9G 0% /dev
tmpfs 790M 19M 771M 3% /run
/dev/md0 46G 2,5G 41G 6% /
tmpfs 3,9G 0 3,9G 0% /dev/shm
tmpfs 5,0M 0 5,0M 0% /run/lock
tmpfs 3,9G 0 3,9G 0% /sys/fs/cgroup
/dev/sdb1
I'm not seeing anything that would show anything to indicate a problem. The
weights, cluster size, etc all say that ceph only sees 30GB per osd. I
don't see what is causing the discrepancy. Anyone else have any ideas?

And the `sudo df -h`? Also a `ceph df` might be helpful to see what's
going on.

Hi David!
lsblk:

The output of `sudo df -h` would also be helpful. Sudo/root is generally
required because the OSD folders are only readable by the Ceph user.

What is the output of `lsblk`?
