ZFS online migration (replication) doesnt work

[Bart Brouwer]

Hi, i have 2 proxmox servers updated till the latest version. (Virtual Environment 5.1-36)
both nodes has ZFS pools with the same name.

Offline migration works fine.

when i want to migrate online, i got this message: (screenshot either). i dont know what state-test disk is.

Your VM uses local disks. Live migration only works if you have shared storage.

 

[Bart Brouwer]

hmm, i thought zfs will give me the option for using local storage and live migration.

i have also a nas with shared storage. live migration works indeed.

But when do i need replication then if i cant bring this VM up on the other node?

For Backup or fail over scenarios.

 

[Bart Brouwer]

ah oke. i thought. handy, if i make replication and migrate, he brings the latest data to this node and goes up.
save for migration and safe as backup.

how could i bring the vm up on the other nodeB when node A fails?
