For example, ifĬrush requires 1 replica on each of 3 racks, but there are fewer OSDs in 1 of Would not allow a pool to ever have completely balanced PGs. This can be set with a command likeĬeph config set mgr mgr/balancer/upmap_max_deviation 2. Upmap_max_deviation which now is an integer number of PGs of deviationįrom the target PGs per OSD. The configuration value osd_calc_pg_upmaps_max_stddev used for upmapīalancing has been removed. New admin command ceph daemon osd.# dump_osd_network willĭo the same but only including heartbeats initiated by the specified OSD. Value determined by the config options, for the average for any of the 3 intervals. List all connections with a ping time longer than the specified threshold or New admin command ceph daemon mgr.# dump_osd_network command will When OSD heartbeat pings take longer than the specified amount. Mon_warn_on_slow_ping_time specified in milliseconds over-rides the Osd_heartbeat_grace to determine the threshold. Option mon_warn_on_slow_ping_ratio specifies a percentage of Intervals with average, minimum and maximum values. The OSD computes 1 minute, 5 minute and 15 minute Time exceeds a configurable threshold for any of the intervalsĬomputed. How many RGW daemons, zones, and zonegroups are present which RGW frontends are in useĪggregate stats about the CRUSH map, like which algorithms are used, howīig buckets are, how many rules are defined, and what tunables are in useĪ health warning is now generated if the average osd heartbeat ping
