Hi Andrej, I wonder if this is another manifestation of the buggy gperftools-libs v2.8 bug, e.g. https://tracker.ceph.com/issues/49618 If so, there is a fixed (downgraded) version in epel-testing now. Cheers, Dan On Tue, Mar 9, 2021 at 4:36 PM Andrej Filipcic <andrej.filipcic@ijs.si> wrote:
Hi,
under heavy load our cluster is experiencing frequent OSD crashes. Is this a known bug or should I report it? Any workarounds? It looks to be highly correlated with memory tuning.
it happens with both nautilus 14.2.16 and octopus 15.2.9. I have forced the bitmap bluefs and bluestore allocator.
the cluster is ~60 nodes with 256GB ram and 25Gb NICs, ~1600 OSDs on 100g network. Typically it is happening when the traffic is above 100GB/s.
Best regards, Andrej
