replication

I have a proxmox cluster where each node has two tiers of storage: fast and small (=SSD or NVME) named "localSSD" and slow and large (=HDD) named "localHDD". Everything is ZFS. The VMs running are not HA configured. They can go down for some time, but preferably not hours/days. Each VM has a...

Hello everyone, I tried to find information about this, but apparently my setup seems to be exotic in this aspect because no one else has done this. I have a small 2 node cluster and plan to add another node with PBS installed to back up all VMs and containers. But also: a whole storage pool...

Hello Proxmox Community! I'm digging into Proxmox internals (literally Perl scripts) a bit, but I can't find answer for my question: what's is the differences in internal implementation between pve-zsync and full storage replication task. As far as I can see both mentioned methods use ZFS...

Two questions: 1. Is it possible to set up automatic replication of a VM between two nodes without replicating all snapshots? I. e. replicating only the current machine state, but not the snapshots taken of it before? I take daily and weekly snapshots (retain six weekly and seven daily) locally...

Hello, in my cluster i have finded a vm with replication faild with this log: -------------------------------------------------------------------------------- 2020-11-02 12:54:01 105-0: start replication job 2020-11-02 12:54:01 105-0: guest => VM 105, running => 15447 2020-11-02 12:54:01 105-0...

Hello I'm quite familiar with Hyper-V replication and migration and I don't really understand the way replication has to be used with proxmox My need is I just want to have 2 nodes on 2 physical hosts and use replication to be able to start the replicated VM on the second physical Host as soom...

I am setting up a tiny cluster - I only need more than one machine to provide fault tolerance (will be using 3 for quorum / simpler upgrade and maintenance cycles). Given that I have 3 physical hosts which is very redundant, I'm not planning on mutliple PSU's/NICs/RAID. To provide resillience...

Update: Believe this has to do with Wireguard VPN, possibly an MTU issue but the high speed going down to a trickle is very odd. If anyone has any insight would appreciate it. Kinda new to Proxmox built in replication but I am very familiar with zfs send / recv Testing out simple storage...

Hello all, I just created this account to ask this question as I can't find the answer elsewhere. I have a VM set up on a 6.2 community edition cluster. It's not using HA, the cluster is quorate and all seems well. The VM has replication set up for the two other nodes. The documentation...

Greetings I'm trying to have a replication job between two nodes of a cluster, like this: pvesr run -id 111-2 -verbose After transfering 173G, the process stops with "cannot receive incremental stream: out of space". The free space on the receiving end is 1.65T. What am I doing wrong? Thanks...

I am looking at the option of configuring a PVE cluster with storage replication (using a ZFS pool across the cluster nodes) so VMs and CTs can be moved to another node if the original host node has a failure. This is probably a PVE independent question but: when I create the initial ZFS...

Hi! Please help me understand for be clear: Example for sure, all works fine, Ceph health OK, VMs are stored in Ceph, by default only node1 running a VMs: node1: 1000 GB OSD (1 HDD) node2: 1000 GB OSD (1 HDD) node3: 1000 GB OSD (1 HDD) node4: 500 GB OSD (1 HDD) node5: 500 GB + 500 GB OSD (2...

Hello I was just testing Proxmox 6.2 and I was wondering why only the second disk of the vm was transferred fully, and first one was just incremental (and the zvol was there). Well, actually it seems that I've just set a replication (from GUI) and forgot about it :p. But the question remains...

I have a PVE cluster with a backup server which I would like to keep turned off most of the time as a "warm spare". Would it be possible to automatically issue a wake-on-lan command before replication jobs are scheduled to run, and shut the node down after all the replication jobs have been...

Hello I have read documentation and topics on forum about this subject but cannot find a clear answer (and the thread How does Replication work in a HA environment? is quite old , 2017) If I have a replicated VM betwen the 2 nodes I'll put this VM in HA configuration, Will HA process use the...

Hello community, Love Proxmox. So much fun to work with! I have a few VMs with local ZFS storage and a 2-Node (still figuring out where to install the 3rd) setup. I setup replication for a VM from node A (where it is currently running) to node B. Does a replication from node B to node A make...

Hi Community, Im Moment befasse ich mich mit dem Replication Feature von Proxmox. Aber da stelle ich mir die Frage wenn mein 1 Server ausfällt, wie kommen meine User dann auf den zweiten Server? Der hat ja eine andere IP etc. wie kann ich das konfigurieren ?

I have 2 Proxmox 6.0 nodes with replication setup between the nodes for a single VM. The replication works, but the freeze and thaw of the guest filesystem causes problems with the application running in the VM. It can't handle the brief pause. Is there a way to do the replication withOUT the...

Hi, we want to replicate our machines every 15 minutes. We scheduled the replication before every two hours: */2:00 Now we want to switch to each 15 minutes but not from 0 to 6 o-clock: mon..sun 06..23:0/15 This works but we do not understand the ':0' part in the pattern. What is the meaning...

Ever since Proxmox 6 came out, we moved towards using Proxmox with ZFS across all physical servers. That is because with the new corosync, we don't need to have multicast traffic between those servers. We have successfully virtualized servers that were previously on bare metal and even started...
