Hi all, Is TCMALLOC_MAX_TOTAL_THREAD_CACHE_BYTES configured just for filestore or can be used for bluestore, too? https://github.com/ceph/ceph/blob/master/etc/default/ceph#L7 Thanks.

It *should* be set to 128MB for both fwiw. There may be slightly less need now with async messenger but we still have a ton of threads flying around allocating memory and I don't think we can get away with lowering it yet. Might be something for interested parties to retest though! :) Mark On 10/13/20 5:46 PM, Seena Fallah wrote:

Thanks for your information. I see ceph-ansible is setting it just for filestore and when I deploy my ceph cluster there is no /etc/default/ceph file for my OSDs and I got confused :)) I have made a PR for it in ceph-ansible. Thanks. On Wed, Oct 14, 2020 at 4:26 PM Mark Nelson <mnelson(a)redhat.com> wrote:
