I am out of office right now, but I am pretty sure it was the same stack trace as in tracker. I will confirm tomorrow. Any workarounds? On Tue, Aug 13, 2019 at 5:16 PM Ilya Dryomov wrote: > > On Tue, Aug 13, 2019 at 3:57 PM Serkan Çoban wrote: > > > > I checked /var/log/messages and see there

I checked /var/log/messages and see there are page allocation failures. But I don't understand why? The client has 768GB memory and most of it is not used, cluster has 1500OSDs. Do I need to increase vm.min_free_kytes? It is set to 1GB now. Also huge_page is disabled in clients. Thanks, Serkan
