Bluestore counts DB/WAL space as "storage" and those areas get a lot of space "used" due to preallocation and things like that, so it looks like your cluster is more used than it actually is, at least if you only count --data-drive space. This is also visible when you create new clusters and haven't written a single byte to it yet, each OSD starts off with some data USED, due to WAL/DB eating some space before first written byte hits the disks. -- May the most significant bit of your life be positive. _______________________________________________ ceph-users mailing list -- ceph-users@ceph.io To unsubscribe send an email to ceph-users-le...@ceph.io
