It would probably help the community if you were to provide more data. Start from scratch and show the exact commands you run and the output.
Don't cut things out, if the output is long - use the SPOILER tag.
Start with no LVM or Multipath, and stop the service if needed. Provide "lsblk", "lsscsi", "blkid"
Add/enable multipath. Provide your exact configuration file "cat /etc/multipath.conf|egrep -v "^$|^#".
What is in your /etc/multipath/wwids
What are the OS and PVE versions? (pveversion). Did you install it from PVE ISO or Debian?
What are the package versions for multipath?
Make sure your system is operational and survives reboot at this point.
What is in your lvm.conf? cat /etc/lvm/lvm.conf |egrep -v "^$|^#| *#"
Only after that add LVM. Make sure you show the commands you use to do so, the state of devices, etc. Follow on with reboot.
Many thousands of people use this configuration at this time, there is something in your workflow that is different but it's hard to say with limited information.
Blockbridge : Ultra low latency all-NVME shared storage for Proxmox - https://www.blockbridge.com/proxmox
i used some guide on the internet for that as expected and merge information from 2 post, PVE 8.2.4 (ISO installed) on no-subscription for now (need a POC to justify the 10k CAD cost of 6 socket premium to my boss) lsscsi return command not found but i included lsblk and blkid with multipath -ll
i think it's about the filter in /etc/lvm/lvm.conf
