An email from this list stated that the wal would be created in the same place as the db, if the db were specified when running ceph-volume lvm create, and the db were specified on that command line. I followed those instructions and like the other person writing to this list today, I was surprised to find that my cluster usage was higher than the total of pools (higher by an amount the same as all my wal sizes on each node combined). This leads me to think my wal actually is on the data disk and not the ssd I specified the db should go to.
How can I verify which disk the wal is on, from the command line? I've searched the net and not come up with anything.
Thanks and regards
