Using Ceph pool for CT fails - rbd kernel module missing

[snooops]

Describe the bug After the installation of the proxmox 8 following the bookworm guide in this wiki, i followed those steps: https://pve.proxmox.com/wiki/Deploy_Hyper-Converged_Ceph_Cluster to setup a ceph cluster. Ceph cluster is up and running among three Raspberry PI 5 8GB systems. If i move a disk from local storage into the ceph storage i get the error message:

modinfo: ERROR: Module rbd not found.
modprobe: FATAL: Module rbd not found in directory /lib/modules/6.6.31+rpt-rpi-2712
rbd: failed to load rbd kernel module (1)

To Reproduce Steps to reproduce the behavior:

1. Install Proxmox 8 using this guide: https://github.com/jiangcuo/Proxmox-Port/wiki/Install-Proxmox-VE-on-Debian-bookworm on three raspberry pi 5 8gb using the sdcard and raspbian 8 bookworm
2. Create a Proxmox Cluster using the webinterface for those three raspberries.
3. Follow this guide to create a proxmox cluster: https://pve.proxmox.com/wiki/Deploy_Hyper-Converged_Ceph_Cluster
4. On the first node: do the ceph init, skip that step on the other two nodes
5. create on each node a ceph mon
6. create on each node a osd device
7. create a pool using pveceph pool create piceph --add_storages
8. Create a CT and assign local storage
9. Once CT is created, try to move CT storage from local storage to piceph storage.

Expected behavior ceph storage works without error.

Update your kernel to support rbd

[snooops]

I googled around and saw this: https://github.com/raspberrypi/linux/issues/6224 I guess in a few days a new kernel with rbd support will come automatically to raspberry pi.
