    I configured 2 nodes.
    Both are connected to the storage, but only one of them can see the volumes :

    - Node 1 :

    upload_2019-3-15_11-49-47.png

    - Node 2 :
    upload_2019-3-15_11-50-3.png

    upload_2019-3-15_11-50-20.png

    Any idea on how to fix it ?

    * Maybe the storage does only allow one node's initiator to access the LUN?
    * You need to configure and allow all node's initiators on the Storage, in order to be able to access it from all nodes

    `pvesm scan iscsi <portal>` can help in seeing whether iSCSI works on the tcp/ip layer.
    afterwards you need to log the node in (the archwiki has quite a nice documentation on the subject : https://wiki.archlinux.org/index.php/Open-iSCSI)

    I finally could figure out


    modprobe -r mptsas;sleep 1; modprobe mptsas


    iscsiadm -m node

    glad to hear the issue is resolved!

    I do wonder why a sas-driver (mptsas is for a familiy of LSI/Avago HBAs) has anything to do with the iSCSI stack though?
