    @SABATIER Brice
    Shared managed disks do not natively offer a fully managed file system that can be accessed using SMB/NFS. You need to use a cluster manager, like Windows Server Failover Cluster (WSFC) or Pacemaker, that handles cluster node communication and write locking. So while it is possible to mount like you have you will need some cluster specific software for this to work. Please refer to the Sample Workloads section for some examples.

    You might consider using Azure Files. This will allow you to read and write to the same location without extra software. Azure Files offers fully managed file shares in the cloud that are accessible via the industry standard Server Message Block (SMB) protocol or Network File System (NFS) protocol. Azure file shares can be mounted concurrently by cloud or on-premises deployments.

    Hey,

    As mentioned, in order to get simultaneous access to the shared drive you will need clustered file system on top. You can deploy Failover Cluster on top of your VMs and add the drive as CSVFS. Depending on your goals, you can work with CSVFS directly or create HA File Server on top to get SMB/NFS access to share. Might help:
