    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...
