hi, I have a nas connected to a server via iscsi. I connected this nas with the same iqn to another server. It seems that at the moment it doesn't give me any problems, but my question is: does it involve problems? Is it a correct procedure? is it not recommended ?.
I would add, if I want to disconnect the iscsi unit, it won't, it warns me that there are active services, what control are they? and how to disconnect them?
Thank you

    Hey,

    In order to work with a single iSCSI LUNs on 2 servers simultaneously you need to have a file system, which can coordinate I/O, as mentioned above CSVFS can handle it.
    https://learn.microsoft.com/en-us/windows-server/failover-clustering/failover-cluster-csvs

    For your case, it is easier to create SMB file share on your NAS and connect it on your servers. The fileserver could be created with StarWind VSAN as a fault-tolerant storage backend for a HA Fileserver. The following guide covers Failover Cluster process creation as well as HA File Share.

    Hi,

    If the NAS storage is shared to different servers, it is normal and recommended that we connect the same IQN to different servers.

    In my test, I have a Windows Server for storage, I created virtual disk with IQN: iqn.1991-05.com.microsoft:dc-target-n1-n1-target. This IQN is configured to allow node 1 and node 2 to connect.

    perfect, I managed to do it. I specify that the two servers are of different domains. When a user of domain 1 creates or modifies shared shared files within the issi, the user of domain 2 does not see the added files and the changes. Because?
