hi, I never recognized the Debian /etc/default/ceph :-) ========= # Increase tcmalloc cache size TCMALLOC_MAX_TOTAL_THREAD_CACHE_BYTES=134217728 ======== that is, what is active now. Huge pages: # cat /sys/kernel/mm/transparent_hugepage/enabled always [madvise] never # dpkg -S /usr/lib/x86_64-linux-gnu/libjemalloc.so.1 libjemalloc1: /usr/lib/x86_64-linux-gnu/libjemalloc.so.1 so file exists on PROXMOX 5.x (Ceph version 12.2.11-pve1) If I understand correct: I should try to set bitmap allocator [osd] ... bluestore_allocator = bitmap bluefs_allocator = bitmap I would restart the nodes one by one and see, what happens. cu denny _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
