Hello
I previously enabled upmap and used automatic balancing with "ceph balancer
on". I got very good results and OSD's ended up with perfectly distributed
pg's.
Now after adding several new OSD's, auto balancing does not seem to be
working anymore. OSD's have 30-50% usage where previously all h

I added `debug mgr = 4/5` to [global] section in ceph.conf on the active
mgr. And restarted mgr service. Is this correct ?
I noticed some config settings in the mgr logs.. Changed config to use

I am testing running manually `ceph osd pg-upmap-items 41.1 106 125`
Nothing shows up in logs on neither OSD 106 or 125 and nothing happens.

Hello
I am trying to diagnose why upmap stopped working where it was previously
working fine.
Trying to move pg 41.1 to 123 has no effect and seems to be ignored.
# ceph osd pg-upmap-items 41.1 23 123
set 41.1 pg_upmap_items mapping to [23->123]
No rebalacing happens and if i run it again it sh

Yeah i agree... the auto balancer is definitely doing a poor job for me.
I have been experimenting with this for weeks and i can make way better
optimization than the balancer by looking at "ceph osd df tree" and
manually running various ceph upmap commands.
Too bad this is tedious work, and tend
Hello
I am using "ceph-deploy osd create --dmcrypt --bluestore" to create the
OSD's.
I know there is some security concern when enabling TRIM/discard on
encrypted devices, but i would rather get the performance increase.
Wondering how to enable TRIM in this scenario ?
