  1. [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...
  2. 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...
  3. 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...
  4. 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)...
  5. 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!
  6. 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...
  7. [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...
  8. [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)...
  9. 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...
  10. 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...
  11. 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...
  12. 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...
  13. 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...
  14. 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...
  15. 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...
  16. zfs replication error - code 255

    Hi, I'm replicating two virtual machines (vm01 and vm02) from node A to node B. vm01 replicates properly, but vm02 doesn't complete the replication. vm02 has three hds. Apparently everything goes smoothly in the replication of disk-0, disk-1 seems to repeat the same piece of replication...
  17. CEPH pool without replication?

    Hi, is it possible to create a CEPH pool that does not replicate and where I have 100% of the storage available? We are talking about temporary data that is unimportant and may be lost. Setting a pool with size/min to 1/1 does not mean that it does not replicate. Hence the question.
  18. Replication of VM between two different ProxMox clusters...

    Hi, Is it possible to replicate one VM between two different clusters on a different locations? For example - I'm running a KVM with Xwiki inside on primary site and if that site goes down - I lost access to all my Wiki information, including vital information about the site itself. That's why...
  19. Is there a way to change the IP addresses in the .members hidden file in /etc/pve directory?

    We have a two node quorate cluster running over WAN, with each node behind a NAT, and we are looking to change the .members hidden file in order to change the IPs for each node to their respective public IP. Currently, when trying to replicate a ZFS pool, the set up fails as its looking to...
  20. ZFS replication of encrypted LXC subvol

    I'm using ZFS encryption on some LXC subvol storage, but found that proxmox replication does not natively support them. A single option needs to be added here ...
