Hello Thomas,
by default we allocate 1GB per Host on the Management Node, nothing on the

This value can be changed in the management container config file

OK, so after some debugging, I've pinned the problem down to
OSDMonitor::get_trim_to:

Sorry, to clarify, you also need to restrict the clients to mimic or
later to use RBD clone v2 in the default "auto" version selection
mode:
$ ceph osd set-require-min-compat-client mimic
Ah, of course, thanks for the clarification.

Dear All,
We are having problems with a critical osd crashing on a Nautilus
(14.2.8) cluster.
This is a critical failure, as the osd is part of a pg that is otherwise
"down+remapped" due to other osd's crashing; we were hoping the pg was
going to repair itself, as there are plenty of free os
I haven't seen any MGR hangs so far since I disabled the prometheus
module. It seems like the module is not only slow, but kills the whole
MGR when the cluster is sufficiently large, so these two issues are most
likely connected. The issue has become much, much worse with 14.2.8.
On 23/03/2020 09
I dug up this issue report, where the problem has been reported before:
https://tracker.ceph.com/issues/39264
Unfortuantely, the issue hasn't got much (or any) attention yet. So
let's get this fixed, the prometheus module is unusable in its current
state.

Hi everyone,
As we wrap up Octopus and kick of development for Pacific, now it seems
like a good idea to sort out what to call the Q release.
Traditionally/historically, these have always been names of cephalopod
species--usually the "common name", but occasionally a latin name
(infernalis).
Maybe just call it Quincy and have a backstory? Might be fun...

Checking the word "Octopus" in different languages the only one starting
with a "Q" is in "Maltese": "Qarnit"
For good measure here is a Maltesian Qarnit stew recipe:

Wait, your client name is just "1"? In that case you need to specify
that in your mount command:
mount ... -o name=1,secret=...
It has to match your ceph auth settings, where "client" is only a
prefix and is followed by the client's name
