[SOLVED] Unable to replicate new VM to new Node

[cbarbie]

I have successfully setup replication before, but this time I am unable to figure out the issue.

I am trying to replicate new VM (105-OpnSense) on node ProxMoxD to a new node on my Test cluster, ProxMoxC.


Both nodes have a ZFS pool called VMs.



I can ping the cluster IP address and the node addresses from each node to all of the other nodes.


The replication job is failing with exit code 255, which seems generic.

2024-05-13 05:29:02 105-0: start replication job
2024-05-13 05:29:02 105-0: guest => VM 105, running => 0
2024-05-13 05:29:02 105-0: volumes => VMs:vm-105-disk-2,VMs:vm-105-disk-3
2024-05-13 05:29:04 105-0: (remote_prepare_local_job) storage 'VMs' is not available on node 'ProxMoxC'
2024-05-13 05:29:04 105-0: end replication job with error: command '/usr/bin/ssh -e none -o 'BatchMode=yes' -o 'HostKeyAlias=ProxMoxC' -o 'UserKnownHostsFile=/etc/pve/nodes/ProxMoxC/ssh_known_hosts' -o 'GlobalKnownHostsFile=none' root@192.168.1.226 -- pvesr prepare-local-job 105-0 VMs:vm-105-disk-2 VMs:vm-105-disk-3 --last_sync 0' failed: exit code 255


Is there a log that would give me additional details?
Am I missing something obvious?

storage 'VMs' is not available on node 'ProxMoxC'

The VM is on the storage "VMs", which does not exist on the target node.
Replication needs the ZFS pool to have the same name between nodes.

Both nodes have the same ZFS pool.



The pool showed up here before I added ProxMoxC (target) to the cluster:

After adding ProxMoxC to the cluster it disappeared.

If I try to add the storage in Datacenter, I get this:


I was able to add VMs_C, but replication still failed with the same 255:

The storage is not active on both nodes.

The steps to create the zfs storage are:

1. Create ZFS on first node. "Add Storage" has to be checked.
2. Create ZFS on second node. "Add Storage" must NOT be checked.
3. Go to Datacenter > Storage. Edit your new ZFS storage. In the field "Nodes:" add the second node.
4. Enable "Thin provision" to get thin provisioned VM HDD images.

One little check box made all the difference!

Thank you!

Great it works now!
