I noticed that in my scenario, when I mount cephfs via the kernel module,
it directly copies to one or three of the OSDs. And the writing speed of
the client is higher than the speed of replication and auto scaling This
causes the writing operation to stop as soon as those OSDs are filled, and

Hi,
I don't think this is going to work. Each OSD belongs to a specific
host and you can't have multiple buckets (e.g. bucket type "host")
with the same name in the crush tree. But if I understand your
requirement correctly, there should be no need to do it this way. If
you structure your
Hi,
I don't quite understand the issue yet, maybe you can clarify.
If I perform a "change volume type" from OpenStack on volumes
attached to the VMs the system successfully migrates the volume from
the source pool to the destination pool and at the end of the
process the volume is visible

This message does not concern Ceph itself but a hardware vulnerability which
can lead to permanent loss of data on a Ceph cluster equipped with the same

Hello guys,
We have a Ceph cluster that runs just fine with Ceph Octopus; we use RBD
for some workloads, RadosGW (via S3) for others, and iSCSI for some Windows
clients.
Recently, we had the need to add some VMWare clusters as clients for the
iSCSI GW and also Windows systems with the use of Clus
Hi, I have a real hardware cluster for testing available now. I'm not
sure whether I'm completely misunderstanding how it's supposed to work
or if it's a bug in the LRC plugin.
This cluster has 18 HDD nodes available across 3 rooms (or DCs), I
intend to use 15 nodes to be able to recover if o
Hi,
so grafana is starting successfully now? What did you change?
Regarding the container images, yes there are defaults in cephadm
which can be overridden with ceph config. Can you share this output?
ceph config dump | grep container_image
I tend to always use a specific image as describe

Hi,
Actually I've learned that it's not needed for a rule to start with a root
bucket, so I can heve rules that will only consider a subtree of my total

BTW: it is possible to have different trees with dif

Hi Eugen,
Thank you very much for these detailed tests that match what I observed
and reported earlier. I'm happy to see that we have the same
understanding of how it should work (based on the documentation). Is
there any other way that this list to enter in contact with the plugin

Hi Patrick,
The event log size of 3/5 MDS is also very high, still. mds.1, mds.3,
and mds.4 report between 4 and 5 million events, mds.0 around 1.4
million and mds.2 between 0 and 200,000. The numbers have been constant
since my last MDS restart four days ago.
I ran your ceph-gather.sh script a
Hi,
adding the dev mailing list, hopefully someone there can chime in. But
apparently the LRC code hasn't been maintained for a few years
(https://github.com/ceph/ceph/tree/main/src/erasure-code/lrc). Let's

Zitat von Michel Jouvin :
Hi Eugen,
Thank you very much for these detaile
I see, thanks for the feedback guys!
It is interesting that Ceph Manager does not allow us to export iSCSI
blocks without selecting 2 or more iSCSI portals. Therefore, we will always
use at least two, and as a consequence that feature is not going to be
supported. Can I export an RBD image via iSC
As a sidenote: there's the windows rbd driver which will get you wy
more performance. It's labeled beta, but it seems to work fine for a lot
of people. If you have a testlab you could try that.

Hello,
I'd like to know is there a way to query some metrics/logs in octopus (or if
has newer version I'm interested for the future too) about the bandwidth used
in the bucket for put/get operations?
Thank you
