Hi, This might be the pglog issue which has been coming up a few times on the list. If the OSD cannot boot without going OOM, you might have success by trimming the pglog, e.g. search this list for "ceph-objectstore-tool --op trim-pg-log" for some recipes. The thread "OSDs taking too much memory, for pglog" in particular might help. Cheers, Dan On Tue, Oct 20, 2020 at 11:57 PM Ing. Luis Felipe DomÃnguez Vega <luis.dominguez@desoft.cu> wrote:
Hi, today mi Infra provider has a blackout, then the Ceph was try to recover but are in an inconsistent state because many OSD can recover itself because the kernel kill it by OOM. Even now one OSD that was OK, go down by OOM killed.
Even in a server with 32GB RAM the OSD use ALL that and never recover, i think that can be a memory leak, ceph version octopus 15.2.3
In: https://pastebin.pl/view/59089adc You can see that buffer_anon get 32GB, but why?? all my cluster is down because that. _______________________________________________ ceph-users mailing list -- ceph-users@ceph.io To unsubscribe send an email to ceph-users-leave@ceph.io
