@LoneExile Thanks for the answer! Unfortunately, I need the Debian version of the distribution because I'm installing Proxmox. I discovered that the default build bookworm_edge_6.6.0-rc1 contains the RBD module. But here I encountered the surprising behavior of the Orange Pi 5 Plus board: now it boots not every time. I literally have to switch the power supply several times until the OS boots. This does not happen on the bookworm_legacy_5.10.160 kernel version. I have three identical Oragne Pis with different power supplies and this problem is reproduced on the bookworm_edge_6.6.0-rc1 kernel. But this is a question for a another thread. Nevertheless thank you!
