I seem to recall this coming up before when bluestore was new, and if I remember correctly the answer was "no", it is not like the journal for filestore where the journal empties itself and can later be lost as long as no writes were ongoing. The WAL (and DB) for bluestore seem to have more important roles than just being a small place to offload incoming writes. -- May the most significant bit of your life be positive. _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
