    Hi

    I am trying to use Storage Replication.
    I have deployied two servers: nodeA and nodeB.
    I actived the Storage Replication in a container VM.
    First replication ran ok...
    I can migrate the VM between nodeA and nodeB.
    I actived HA between this two nodes! I know, this a no-recommended behavior... But don't worry! It's just a lab environment!
    So when the nodeA has crash, the Vm restarted in nodeB. That is expected behavior.
    But, when the nodeA has back online, I cannot migrate the VM from nodeB to nodeA.
    I get this error:

    TASK ERROR: migration aborted

    In order to remediate this BAD behavior, I maked a script in nodeB, that destroy de zvol in nodeA, and perform a migration. The scipt below do the job:
    #!/bin/bash

    ssh root@pve01 zpool destroy ZFS-LOCAL -f
    ssh root@pve01 zpool create ZFS-LOCAL /dev/vdb -f
    ha-manager migrate ct:101 pve01

    I don't know if this a bug or what!

    Whatever it is, I don't have a clue in how to fix it!

    Somebody can help???

    Thanks a lot

    Yes this is known. It is not implemented yet.
