replication

  1. 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...
  2. 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...
  3. Issue upgrading from 6 to 7

    Hello, in a two nodes cluster Master/Slave i have upgraded the Slave (empty) from proxmox 6 to 7. After this, replication stop working, so i can't migrate my VM from the Master (v6) to the Slave (v7) to perform the upgrade on the Master too. Any ideas ? Thanks!
  4. 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
  5. [SOLVED] Unsicherheit beim Löschen von disks/subvols

    Hallo, ich habe zwei Fragen, bei deren Beantwortung ich mir nicht sicher bin. Zum Hintergrund: ich habe ein Cluster mit 3 PVE’s (7.2.7) mit ZFS + PBS. Ich habe keine HA-Konfiguration (keine gemeinsames Storage sondern lokale SSD’s) sondern repliziere meine wichtigen VM’s / CT’s zyklisch...
  6. [TUTORIAL] Long Replication-Time caused by Office 2019 and Microsoft VSS

    Hello Maybe someone can help this too Problem was that Replication-Time on Windows RDS Hosts with installed Office 2019 took long time. About 5 to 90 minutes each job. After some investigation i noticed, that the Replication-Log hangs after „freeze guest filesystem“. Same time on vm, the...
  7. 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...
  8. Host names and Cluster

    Hey all, I deployed two servers in a cluster previously and how finished deploying 3rd for HA and having some issues with getting replication working on all three. it seems to be ssh key and hosts related, then dug deeper and likely to do with my host names being wrong. Currently 3 servers are...
  9. 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)...
  10. Window VPS lose Network connection during Replication

    Hello, I notice on some instances of Windows Server 2016 the loss of the network when the replication starts. When I log in the icon has an exclamation point and I have to disable the network and reactivate it. Did it happen to you? Some Windows logs: Thanks!
  11. 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...
  12. [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...
  13. [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)...
  14. HA - lan disconnect

    I understand that as home user of a 3 node proxmox setup I am somewhat different than the pro users. but I like to play and to understand the features Proxmox is giving me. I had HA configured with replication of 2 machines and saw how proxmox was handling the priorities, so far all ok for this...
  15. Intermittent sync issue

    We have some intermittent sync issue when syncing between 2 PBS. Here's the log: 2021-10-31T03:01:27-04:00: sync group vm/108 failed - unable to acquire lock on snapshot directory "/mnt/nas/vm/108/2021-10-30T04:04:17Z" - internal error - tried creating snapshot that's already in use It's...
  16. could not activate storage 'local-zfs', zfs error: zpool: symbol lookup error: zpool: undefined symbol: zpool_get_prop_literal (500)

    Hello, We have two nodes that have started to fail when replicating They used to work fine. command '/usr/bin/ssh -e none -o 'BatchMode=yes' -o 'HostKeyAlias=proxmox2' root@10.1.0.241 -- pvesr prepare-local-job 109-0 local-zfs:subvol-109-disk-0 --last_sync 0 --parent_snapname Limpio' failed...
  17. Is it possible: PVE + shared storage + HA + replication to remote site?

    All of my previous experience of PVE setups related to stand-alone hosts, and PVE is perfect for that. Now we want to connect shared SAN storage to several PVE hosts to have HA available. SAN (we rent it) seems to be FC connected. At the same time we want to have the same VMs copied...
  18. SLOG and L2ARC to speed up ZFS on a spinning drive

    Hi, I'm running a PVE cluster at home, mostly for fun and some local services. I deployed it on top of a couple of dell optiplex (for the low power consumption), which have 1 NVME slot and 1 SATA slot. Initially, I put one 1TB NVME SSD inside both of the optiplex, partitionned with ZFS, and 16...
  19. How to Replicate a vm between two nodes?

    Hi There, I'm trying to achieve a replication of a VM(id100) from Node A to Node B (and vice versa) - so when i make changes on VM that resides on NodeA it replicates that change to NodeB VM, yes i know that must be ZFS but i cant understand when in my scenario i have two nodes both nodes have...
  20. zfs snapshot hooking

    Hi, lads and ladies. I stuck with one little trouble about topic. I have a lot of VMs and CTs in a Proxmox environment, zfs-based. Some of them contains db or other services, that *CAN* restore after unclean shutdown, but it would be better to have them *CLEAN* at snapshot taken. I'm using...
