    ZFS: Storage space for zvols almost doubles when transferred to raid-z3 pool

    I'm running a ZFS raid-z3 zfs pool on a Proxmox node that serves as a backup host. I create snapshots on different Proxmox hosts with ZFS mirror pools and pull them to the backup node. I noticed that the same snapshots of zVOLs are occupying almost twice the storage space on the backup node...

    Cold Redundancy of a VM in a cluster of two nodes

    Hello, I need help managing the redundancy of a VM. At the moment I have 2 physical machines in Cluster MAIN and BACKUP (Proxmox 7.3) both configured: in RAID1 ZFS (directly from the ProxMox installation). The two machines have two 1TB SSDs. I know I can't have HA since I don't have 3 nodes...

    Best way to have hot spare + backup at the same time with PVE on ZFS (with pvesr & sanoid)

    Syncoid (dataset synchronization between two different machines) and Sanoid (creation and prune of snapshots) are two ZFS (high-level) tools that combined give you hot spares (syncoid) and backups (sanoid) to roll back to them if necessary. Proxmox has the storage replication feature (pvesr)...

    ZFS replication & migration fails after migration (CT & VM)

    Hello everybody, After tinkering a little big with PBS, I have uninstalled it and installed PVE too in my second node. Then I have tried to set up replication between both of my nodes. Everthing worked well at the end. Then I tried migrating a CT and a VM to my new node. After that, in the web...

    Odd problem with auto-migrated VMs to wrong hosts, plus how best to disable HA for now?

    We have a Proxmox cluster comprising two identical large machines, with 120 cores and 370+ gig of memory, and with each machine having two ZFS disk pools, Tank1 of 50TB HDD, and Tank2 of 2TB of SSD, and a third less powerful machine with just one ZFS pool, a mirrored paid of 10TB disks...

    Proxmox VM DR Scenario

    Hello everyone, I have two different Proxmox VE clusters in my data center located in two different geographies. I want to replicate for DR of VMs running on Proxmox. Currently, I can provide this with file system replication on Storage, but it is not very useful. Do anyone protect against DR...

    questions about replication and zfs

    Hello, I was hoping to get some clarification about zfs and replication. my VM 104 is running on Proxmox2 in my cluster. I set up a replication task to replicate it to proxmox1 in my cluster. Is the VM on proxmox2 using the snapshot or is it safe to delete the snapshots? (this goes for all...

    BTRFS and VM replication

    I am testing Proxmox with BTRFS and I missed VM replication. VM migration works fine. Is there any roadmap for VM replication on BTRFS? I tested using Proxmox version 7.2.7 Thanks, Ricardo Jorge

    One way only replication.

    Hi, I have a 2 node PVE (with a third corosync quorum node), with replication configured. I'd like to have one way replication only, so that when node A is active, it does replicate on node B, but when node B became active, it does not replicate VMs back to node A. That's because replication...

    Could you use proxmox with ceph for geo-failover ?

    Im trying to find a way to use proxmox with ceph as a multi site failover cloud setup of some sorts :). So i have 2 proxmox clusters with ceph, in different locations. They see each-other via site-to-site vpn, and have configured mirroring (journaling) with rbd on a pool (on all its images)...

    ZFS replication sometimes fails

    We're currently testing ZFS replication in order to use it on our production servers. I made a test cluster of 3 nested Proxmox VMs: at1, at2 and at3. Each node has a single 16GB drive with a ZFS pool. I created a VM and a container (referred to as "VMs" from now on) on at1, enabled...

    [SOLVED] Is is possible to specify the NIC used for storage replication?

    I have a 3 node cluster running PVE 7.1-10. I am successfully replicating a pfsense VM between two nodes in my cluster, but it's going over my LAN NIC instead of my dedicated cluster network. Is there a way I can specify the NIC for replication? Even better, can I specify a primary and...

    [SOLVED] Replication in cluster - different ZFS storage on nodes - not available on node

    I have extended a test cluster with a new machine (called: pmx1885) which has its ZFS pool setup done after the install with the web-gui not with the installer (during installation time). This differs from my other cluster nodes in this case. The other cluster nodes (pmx2b,pmx1b,pmx2a,pmx1a)...
