Hi.
I just changed some of my data on CephFS to go to the EC pool instead
of the 3x replicated pool. The data is "write rare / read heavy" data
being served to an HPC cluster.
To my surprise it looks like the OSD memory caching is done at the
"split object level" not at the "assembled object leve
@Paul Emmerich Thank you very much!. That did the trick!

Why did you choose compat mode? Don't you want to try another one instead?

what's your 'ceph osd df tree' outputs？does the osd have the expected PGs?

i think the write data will also write to the osd.4 in this case.
bc your osd.4 is not down, so the ceph don't think the pg have some osd
down,
and it will replicated the data to all osds in actingbackfill set.

Did you osd oom killed when cluster doing recover/backfill, or just
the client io?
The configure items you mentioned is for bluestore and the osd memory
include many other
things, like pglog, you it's important to known do you cluster is dong recover?

From the error message, i'm decline to that 'mon_max_pg_per_osd' was exceed,
you can check the value of it, and its default value is 250, so you
can at most have 1500pgs(250*6osds),
and for replicated pools with size=3, you can have 500pgs for all pools,
you already have 448pgs, so the next pool ca
