Re: Unexplainable high memory usage OSD with BlueStore

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.
