osd_memory_target is 4294967296. Cluster setup: 3 mon, 3 mgr, 21 osds on 3 ceph-osd nodes in lvm scenario. ceph-osd nodes resources are 32G RAM - 4 core CPU - osd disk 4TB - 9 osds have block.wal on SSDs. Public network is 1G and cluster network is 10G. Cluster installed and upgraded using ceph-ansible. On Thu, Aug 27, 2020 at 7:01 PM Eugen Block <eblock(a)nde.ag> wrote:

Yes, each osd node has 7 osds with 4 GB memory_target. On Fri, Aug 28, 2020, 12:48 PM Eugen Block <eblock(a)nde.ag> wrote:

Can you try the opposite and turn up the memory_target and only try to start a single OSD? Zitat von Vahideh Alinouri <vahideh.alinouri(a)gmail.com>om>:

One of failed osd with 3G RAM started and dump_mempools shows total RAM usage is 18G and buff_anon uses 17G RAM! On Mon, Aug 31, 2020 at 6:24 PM Vahideh Alinouri <vahideh.alinouri(a)gmail.com> wrote:

Hi, Wido had an idea in a different thread [1], you could try to advise the OSDs to compact at boot: [osd] osd_compact_on_start = true Can you give that a shot? Wido also reported something about large OSD memory in [2], but noone commented yet.
