    Replication Failure

    I'm trying to setup replication between two nodes to have a copy on each node as well as backups in PBS and TrueNAS. I have setup PBS and will do TruNAS later. I currently have both nodes setup with ZFS pools though they do have vastly different configurations. Each node has it own local ZFS...

    What's the path of replicated disks and volumes?

    Hello. I have a cluster with no shared storage. I have configured replication. If a node fails, I am supposed to manually migrate the already replicated guests through the CLI following these instructions: https://pve.proxmox.com/pve-docs/chapter-pvesr.html#_migrating_a_guest_in_case_of_error...

    Renaming ZFS Storages in a Cluster for Replication

    Hi everyone, I've set up a three-node Proxmox cluster using ZFS, but I just realized—after searching the forums—that I made a mistake in my storage configuration. I assigned different ZFS pool names on each node, so when I try to configure replication, Proxmox fails because it expects the same...

    Proxmox HA VM with unreplicated scratch disk

    I have a VM in a HA group. Its primary disk is replicated to the other nodes, and the VM is able to migrate between nodes. I need to add a scratch/temp disk to the VM for intermediate writes. This disk doesn't need to be replicated if the VM migrates to a new node; a disk simply needs to exist...

    Migration from VMware to Proxmox: Reusing Hardware Proxmox-SAN

    What are the best storage configurations in Proxmox to access a SAN with multiple nodes while ensuring high performance, redundancy, and simultaneous access? How do options like ZFS over iSCSI, ZFS over NVMe/TCP, Ceph compare in terms of latency, scalability, and complexity? The goal is to...

    API: get running replications (before node update)

    Hello, currently I'm writing an ansible / python / proxmoxer update script for my 2,5-node(*) cluster using the webapi for proxmox. Before I start an update for a node, I set the maintainence mode and disable all replication jobs. I can get all replication jobs via webapi - but how can I check...

    pve-zsync: still supported?

    As part of investigating different options for ZFS dataset replication under proxmox, I've comes across a tool called `pve-zsync`.This appears to be for syncing zfs datasets between hosts, a bit like how `pvesr` syncs the zfs disk images between hosts. I'm struggling to understand if `pve-zsync`...

    Number of concurrent storage replication tasks per host?

    Does anyone know if it's possible to have more than a single VM replication task run from a given host system at one time? Asking because in secure environments (ie using ssh for passing replication traffic) it can take a fair while for a given VMs storage to be replicated to other hosts. This...
