Replication restore

[Alexandre Aguirre]

Hello good day !

I'm doing a simple basic replication lab, I have 2 clustered nodes all working, replication also working, my question is, how do I proceed in case node 1 goes out? how do i get node replicated disk on node 2?

Thank you in advance for your attention.

Hello !

Yes I looked at this documentation friend, but could not understand certainly how it works.

But I will give one more analysis.

Thanks for listening.

Hi,

Replication works when nodes are up and running.

After the first replication cycle is done, all nodes will have a "copy" of the VM.

You can not live migrate a VM if this VM is using local storage.

With local storage VM can be migrated in offline state only.

If a node fails, you must manually move the VM from the failed node to the remaining operating node.

This is explained here :

=======================
move both guest configuration files form the origin node A to node B:

# mv /etc/pve/nodes/A/qemu-server/100.conf /etc/pve/nodes/B/qemu-server/100.conf
# mv /etc/pve/nodes/A/lxc/200.conf /etc/pve/nodes/B/lxc/200.conf
=======================

Regards,

Ricardo Jorge

Thanks buddy !

I will perform the tests here and return for feedback

Good afternoon !

Sorry to ask again, but I'm still in doubt when node 1 gives physical problem in the hardware and is not turning on, how do I go up the node on replicated node 2?

Grateful for the attention !

please read the reference docs carefully - they explain the case quite well IMHO: https://pve.proxmox.com/pve-docs/chapter-pvesr.html#_migrating_a_guest_in_case_of_error

if you still have questions afterwards - please ask with a bit more detail/specifics

hope this helps!

Hello proxmox community.
I am planing, coparing data availability on some solutions like Replication or DFS wiht ceph. I am reopening this thread to ask how to replicate data (VM) to other node (reading WIKI ) if for example disk in failed active node A broke (so we can not get it working again)
I am planing nvme solution with one 2TB disk in all (two (Replication) or three nodes(HA with CEPH)).

Thank you for your attention in advance. Erik
