Quoting Frank Schilder (frans(a)dtu.dk):
Dear Stefan,
I check with top the total allocation. ps -aux gives:
USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND
ceph 784155 15.8 3.1 6014276 4215008 ? Sl Jan31 932:13 /usr/bin/ceph-osd

These should have 8GB resident by now, but stay at or just below 4G. The other options
are set as
[root@ceph-04 ~]# ceph config get osd.243 bluefs_allocator
bitmap
[root@ceph-04 ~]# ceph config get osd.243 bluestore_allocator
bitmap
[root@ceph-04 ~]# ceph config get osd.243 osd_memory_target
8589934592
What does "bluestore_cache_size" read? Our OSDs report "0".
Gr. Stefan
