Hi Robert,

bluestore_allocated just tracks how many space was allocated from slow(aka block) device to keep actual user data. It has nothing about DB and/or WAL.

There are counters in bluefs section which track corresponding DB/WAL usage.

Thanks,

Igor

 I have created new OSDs for Ceph Luminous.  In my Ceph.conf I have specified that the db size be 10GB, and the wal size be 1GB.  However when I type ceph daemon osd.0 perf dump I get: bluestore_allocated": 5963776

 I think this means that the bluestore db is using the default, and not the value of bluestore block db size in the ceph.conf. Why is this?

 Thanks
