    Hello !

    I try for the first time to make a HA PVE, and I am lost a little bit

    I have 4 nodes in cluster connected using SAS connection to the storage (HP P2000 G3 SAS SAN).
    Mutipath is configured and working fine.

    I tried using LVM and ZFS it work fine on all nodes.

    But I am lost for the next step to be able to do live migration and HA.
    What storage type should I use ?

    Can I still use ZFS over scsi even if my storage is attached using SAS and not ethernet ?
    Should I use another storage ?

    Help

    No, you can never use ZFS on any HA-based storage backend. ZFS is a single-host filesystem and you cannot use it on multiple nodes at the same time - it can only be accessed/opened on one node.

    Just use LVM (not thin, this is also not cluster compatible) and use it. It supports HA migration.

    Thank you for the reply !

    Yes, this is what I did and it is working fine !

    My only regret is that I can not make any snapshot.

    Best regards !

    Oh .... I therefore have one node with local ZFS storage on multiple SSDs to play around with a new VM, snapshot it and do all the stuff i wanted to test and it then "moves to production" on the SAN. This works very well and is IMHO the best solution for such "problems".
