I was using some cheaper ssds for monitors and was wondering why they had already written 80 TB after 8 month. 3.8MB/s? That's a little more than I would naively expect, but LevelDB is probably doubling the total data written (at least), so that brings it down to 1.9MB/s of real data. How big is your PGMap and OSDMap? Do you have any logging being written to those SSDs? Etc. ;) _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
