Thank you all for your help. @Adam From the reading you gave me I have understood the following : 1 - Set osd_memory_target_autotune to true then set autotune_memory_target_ratio to 0.2 2 - Or do the math. For my setup I have 384Go per node, each node has 4 nvme disks of 7.6To, 0.2 of memory is 19.5G. So each OSD will have 19G of memory. Question : Should I take into account the size of the disk when calculating the required memory for an OSD? I have another problem, the local registry. I deployed a local registry with the required images, then I used cephadm-ansible to prepare my hosts and inject the local registry url into /etc/container/registry.conf file Then I tried to deploy using this command on the admin node: cephadm --image 192.168.2.36:4000/ceph/ceph:v17 bootstrap --mon-ip 10.1.0.23 --cluster-network 10.2.0.0/16 After the boot strap I found that it still downloads the images from the internet, even the ceph image itself, I see two images one from my registry the second from quay. There is a section that talks about using a local registry here https://docs.ceph.com/en/reef/cephadm/install/#deployment-in-an-isolated-env..., but it's not clear especially about the other images. It talks about preparing a temporary file named initial-ceph.conf, then it does not use it???!!! Could you help? Regards. Le jeu. 22 févr. 2024 à 11:10, Eugen Block <eblock@nde.ag> a écrit :
Hi,
just responding to the last questions:
- After the bootstrap, the Web interface was accessible : - How can I access the wizard page again? If I don't use it the first time I could not find another way to get it.
I don't know how to recall the wizard, but you should be able to create a new dashboard user with your desired role (e. g. administrator) from the CLI:
ceph dashboard ac-user-create <username> [<rolename>] -i <file_with_password>
- I had a problem with telemetry, I did not configure telemetry,
then
when I clicked the button, the web gui became
inaccessible.....????!!!
You can see what happened in the active MGR log.

Hi,
I have some questions about ceph using cephadm.
I used to deploy ceph using ceph-ansible, now I have to move to cephadm, I am in my learning journey.
- How can I tell my cluster that it's a part of an HCI deployment? With ceph-ansible it was easy using is_hci : yes - The documentation of ceph does not indicate what versions of grafana, prometheus, ...etc should be used with a certain version. - I am trying to deploy Quincy, I did a bootstrap to see what containers were downloaded and their version. - I am asking because I need to use a local registry to deploy those images. - After the bootstrap, the Web interface was accessible : - How can I access the wizard page again? If I don't use it the first time I could not find another way to get it. - I had a problem with telemetry, I did not configure telemetry, then when I clicked the button, the web gui became inaccessible.....????!!!
