Did an EC-aware version of this calculator ever escape the Red Hat paywall?

Hi,
In a fresh quincy install, when I type the command to add a host, I get this error:
ceph orch host add gpuno02 10.0.100.2
Error EINVAL: Command ['which', 'python3'] failed. which: no python3 in (/sbin:/bin:/usr/sbin:/usr/bin)
The output of the which command:

Which weights (CRUSH or reweight?) And which balancer?
Assuming the ceph-mgr balancer module in upmap mode, you’d want the reweight
values to be 1.000 since it uses the newer pg-upmap functionality to distribute

Hi David,
Something else you could try with that other pool, if it contains little or
no data, is to reduce the PG number. This does cause some backfill
operations as it does a pg merge but this doesn't take long if the pg is
virtually empty. The autoscaler has a mode where it can make

Hi Erdem,
The balancer was driving all the weights to 1.0 so I turned it off. The
OSDs were creeping up to the 90% full threshold with it turned on. I've been
playing whackamole with the OSDs for a week trying to keep the cluster from
locking all writes when a single OSD goes over 90%.

Hi Richard,
Thanks for that. It never occurred to me that we'd need at least 10
servers for that shape of EC. We will certainly push to get that new
server in now.

Using Quincy I'm getting a much worse lag owing to ceph syslog message
volume, though without obvious system errors.
In the usual case of no current/active hardware errors and no software
crashes: what config settings can I pick so that what appears in syslog

Dear Ceph community,
We are having an issue with the MGR progress module:
Module 'progress' has failed: ('e7fb29e3-9caf-4b20-b930-cee8474526bb',)
We are currently on ceph version 16.2.7

I'm aware that there are already issues an
Hi David,
I think you're right with your option 2. 512 pgs is just too few. You're
also
right with the "inflation" but you should add your erasure bits to the
calculation, so 9x512=4608. With 144 OSDs, you would average 32 pgs per OSD.
Some old advice for that number was around 100.
But your cur
Hi Gregory
Thanks for your confirmation. I hope I can start some tests today.
Cheers

Hello all,
how important is it to use the same Linux kernel version on all Hosts?
Background is, that new hosts are installed with the actual Ubuntu server
22.04 while the older ones run with Ubuntu 20.04.
In other words: may I disable this check:
ceph cephadm config-check disable kernel_versio
Hi,
can you share your 'ceph osd tree' so it easier to understand what
might be going wrong. I didn't check the script in detail, what
exactly do you mean by extending? Do you create new hosts in a
different root of the osd tree? Do those new hosts get PGs assigned
although they're in a d
