Hello, unfortunately ReadWriteMany does not work with this plugin.
You can find the CSI-plugin for such cases here https://kubernetes-csi.github.io/docs/drivers.html

Thanks.

Hi @sergelogvinov, is there any possibility of implementing ReadWriteMany?

[sergelogvinov]

Hello, the plugin uses block devices to attach and detach PVCs to VMs. There is no easy way to support ReadWriteMany access. As far as I know, well-known providers also do not offer this feature for block devices — instead, they use S3, NFS, or other file/object-based storage systems.

The latest release of Proxmox 8.4 introduces a new file system, VirtioFS, which can be used for ReadWriteMany PVCs within a single zone (Proxmox node). However, it is currently not dynamically attachable. For now, I recommend using NFS or S3 to achieve ReadWriteMany functionality

Could that be implemented for Ceph? ReadOnlyMany would already be really useful to me.
