[ceph-users] OSDs taking too much memory, for pglog

Several OSDs of one of our clusters are down currently because RAM usage has increased during the last days. Now it is more than we can handle on some systems. Frequently OSDs get killed by the OOM killer. Looking at "ceph daemon osd.$OSD_ID dump_mempools", it shows that nearly all (about 8.5 GB) is taken by osd_pglog, e.g. "osd_pglog": { "items": 461859, "bytes": 8445595868 }, We tried to reduce it, with "osd memory target" and even with "bluestore cache autotune = false" (together with "bluestore cache size hdd"), but there was no effect at all. I remember the pglog_hardlimit parameter, but that is already set by default with Nautilus I read. I.e. this is on Nautilus, 14.2.8. Is there a way to limit this pglog memory? Cheers Harry
