Hi
How can we enable bluestore_default_buffer
Hi Haung,
So you are suggesting that even though osd.4 in this case has weight 0,
it's still getting new data being written to it? I find that counter to
what weight 0 means.
Thanks

For testing purposes I set a bunch of OSD to 0 weight, this correctly
forces Ceph to not use said OSD. I took enough out such that the UP set
only had Pool min size # of OSD (i.e 2 OSD).
Two Questions:
1. Why doesn't the acting set eventually match the UP set and simply point
to [6,5] only
2. Why
Look here

Of course, please be aware that your clients must be recent enough
(especially for kernel clients).
Sadly, if the compat-level is too old for upmap, you'll only find a small
warning about that in the logfiles,
but no error on terminal when activating the balancer or any other
Can anyone help with this? Why can't I optimize this cluster, the pg counts
and data distribution is way off.

I enabled the balancer plugin and even tried to manually invoke it but it
won't allow any changes. Looking at ceph osd df, it's not even at all.
Thoughts?

Set 3 osd to "out", all were on the same host and should not impact the
pool because it's 3x replication and CRUSH is one osd per host.
However, now we have one PG stuck UKNOWN. Not sure why this is the case, I
do have background writes going on at the time of OSD out. Thoughts?

Hello,
My manager keeps dying, the last meta log is below. What is causing this? I
do have two roots in the osd tree with shared hosts(see below), I can't
imagine that is causing balancer to fail?

Hello,
Been working on Ceph for only a few weeks and have a small cluster in VMs.
I did a ceph-ansible rolling_update to nautilus from mimic and some of my
PG were stuck in 'active+undersized+remapped+backfilling' with no progress.
All OSD were up and in (see ceph tree below). The PGs only had 2
