Note that the code looks for wal/db devices in the block device's LV tags after it is found. In other words:

sudo lvs -o lv_tags | grep type=block | grep ceph.wal_device
sudo lvs -o lv_tags | grep type=block | grep ceph.db_device

This is the window where the following might not yet exist, yet we know they *should* exist based on the above tags:

sudo lvs -o lv_tags | grep type=wal
sudo lvs -o lv_tags | grep type=db
