replication

  1. Replication between clusters

    How would I replicate a VM between two different clusters/subnets over a WAN?
  2. [SOLVED] Replication Job löschen der auf entferne Node zeigt

    Hallo zusammen, ich musste ein paar Veränderungen an unserem Cluster vornehmen, bei dem per storage replication (lokales ZFS) die VMs zwischen den Nodes repliziert werden. Eine Node musste ich dabei aus dem Cluster entfernen und habe sie neu aufgesetzt und sicherheitshalber unter neuem Namen...
  3. Proxmox Replication - Storage full, even though it isn't

    Hey, I am migrating from CentOS to proxmox and have a problem setting up my storage: I've got two machines, each with 2* Samsung 1TB SSDs (mirrored), both running Proxmox. I've got one VM with a 800GB raw image on machine one and want to replicate it onto machine two. So I first set up the zfs...
  4. [SOLVED] pve replication - invalid json

    Hi, one node A down, the vms were being replicated on node B. However, when viewing the replication through the graphical interface, the following message appears: invalid json data in '/var/lib/pve-manager/pve-replication-state.json' (500) the json file is corrupted: pst0 ^ D ^ K ^...
  5. Replicate to different storage - or backup?

    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...
  6. [SOLVED] backup Storage pool

    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...
  7. pve-zsync vs storage replication: differences in the internals

    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...
  8. Replication without snapshots & stop replication job.

    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...
  9. Replication Failed and "state" snap finded

    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...
  10. Good and simple way to use replication ?

    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...
  11. Design - Replication and backups

    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...
  12. Storage Replication - Starts fast and then slows to a crawl, second dataset slow from start. Using another way to send snapshots goes full speed.

    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...
  13. [SOLVED] Replication doesn't speed up migration (6.2 community edition)

    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...
  14. ZFS replication gives "our of space"

    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...
  15. Cluster: Host node ZFS redundancy with additional (storage) replication for VMs /CTs - best practice?

    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...
  16. Smaller size OSD - bigger VM, what happening? Ceph OSD, replication settings.

    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...
  17. [SOLVED] ZFS replication for VMs with multiple disks

    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...
  18. [SOLVED] How to wake and shutdown spare server for replication jobs?

    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...
  19. HA for replicated VM

    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...
  20. VM Replication - Two-way?

    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...
