Dear Cephalopodians,
I performed several consistency checks now:
- Exporting an RBD snapshot before and after the object map rebuilding.
- Exporting a backup as raw image, all backups (re)created before and after the
object map rebuilding.
- md5summing all of that for a snapshot for which the re

Hi Bryan,
I think this is the old hammer thread you refer to:
http://lists.ceph.com/pipermail/ceph-users-ceph.com/2016-September/013060.html
We also have osdmaps accumulating on v12.2.8 -- ~12000 per osd at the moment.
I'm trying to churn the osdmaps like before, but our maps are not being trimm

Hi all,
I wanted to test Dan's upmap-remapped script for adding new osd's to a
cluster. (Then letting the balancer gradually move pgs to the new OSD
afterwards)
I've created a fresh (virtual) 12.2.10 4-node cluster with very small disks
(16GB each). 2 OSD's per node.

Hello, Ceph users,
I am not sure where to report the issue with the ceph.com website,

there are two config options of mon/osd interaction that I don't fully
understand. Maybe one of you could clarify it for me.

mdbox.

Hallo,
I have the same issue as mentioned here, namely
converting/migrating a replicated pool to an EC-based one. I have ~20 TB
so my problem is far easier, but I'd like to perform this operation
without introducing any downtime (or possibly just a minimal one, to
rename pools).

I just had this question as well.
I am interested in what you mean by fullest, is it percentage wise or raw
space. If I have an uneven distribution and adjusted it, would it make more
space available potentially.
Thanks

Ran into issues with bionic upgrades, and had to eventually revert from the
ceph repos to the Ubuntu repos where they have 12.2.8, which isn’t ideal.

Hi everyone, I have some questions about encryption in Ceph.
1) Are RBD connections encrypted or is there an option to use encryption
between clients and Ceph? From reading the documentation, I have the
impression that the only option to guarantee encryption in transit is to
force clients to encry
Hi,
AFAIK, there is no encryption on the wire, either between daemons or
between a daemon and a client
The only encryption available on Ceph is at rest, using dmcrypt (aka
your data are encrypted before being written on disk)

I think Ilya recently looked into a bug that can occur when
CONFIG_HARDENED_USERCOPY is enabled and the IO's TCP message goes
through the loopback interface (i.e. co-located OSDs and krbd).
Assuming that you have the same setup, you might be hitting the same
bug.

Hi,
as others pointed out, traffic in ceph is unencrypted (internal traffic
as well as client traffic). I usually advise to set up IPSec or
nowadays wireguard connections between all hosts. That takes care of
any traffic going over the wire, including ceph.
