Hi, In a cluster where the failure domain is the host and dozens of hosts, the 85% default for nearfull ratio is fine. A host failing won't suddenly make the cluster 99% full. In smaller clusters, with 10 hosts or less, it is likely to not be enough. And in larger clusters 85% may be too much to reserve and 90% could be more than enough.
Is there a way to calculate the optimum nearfull ratio for a given crushmap ? Cheers -- Loïc Dachary, Artisan Logiciel Libre _______________________________________________ ceph-users mailing list [email protected] http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
