replication

Hi There, Is there a technical reason why Online / Live Migration of VMs that are replicated across local disks (from Node 1 local-zfs to Node 2 local-zfs) does not currently seem to be permitted? If this is not currently permitted / available, is it planned to be made available in Proxmox 6...

In a replicated ZFS environment, containers can be easily migrated from one node to another, as the only supported migration mode of a running container is restart mode. It works quick and reliably if replication happends e.g. hourly or more often. For VMs, the system does not allow to select...

Hello everyone, I'm currently moving my virtual machine infrastructure from VMWare to Proxmox and have noticed a few things that seemed odd (at least to a beginner). Firstly, I've been able to ssh between the nodes in my cluster without entering the password (for example, I'm logged in as root...

Hello, just added 2 new nodes to my cluster, without errors, but when i try to replicate i have this error: 2019-06-18 10:44:01 108-2: (remote_prepare_local_job) Host key verification failed. 2019-06-18 10:44:01 108-2: (remote_prepare_local_job) 2019-06-18 10:44:01 108-2: end replication job...

Hi all! I been getting some trouble with my hosts randomly rebooting on me. It has happened a few times now and I don't know how to investigate it. Below are the syslogs immedietely before and after the last reset. Notice the "^@^@^@^@" which I would guess is where something (watchdog?) reset...

I have the following file system that gets replicated to two other PVE nodes: root@carrier:~# zfs list -ospace -tall -r rpool/data/subvol-104-disk-2 NAME AVAIL USED USEDSNAP USEDDS USEDREFRESERV USEDCHILD rpool/data/subvol-104-disk-2...

Hi all, We are currently running a PVE cluster with multiple machines and serve about 15 LXC containers and 10 VMs. We are using PVE replication (every 15min) to onsite PVE machines and znapzend to create hourly snapshots that are also replicated off site. This should protect us against a...

Currently Proxmox VE only enables us to set QUOTA (space used including snapshots), but in many setups it also makes sense to set REFQUOTA (space used excluding snapshots). I have deployed znapzend for automatic ZFS snapshoting and replication, but these automatic snapshots are eating up...

Hello! We have a couple of servers configured to use local ZFS pools for storage. These pools have Thin Provisioning enabled. I used to think that Thin Provisioning + ZFS was enough to have the VMs use on physical storage the same space that they are using into themselves, but it seems I was...

Moin werte Kollegen, unser Cluster speichert mit CEPH, zeitgleich möchte ich in ein "Notfalldatacenter" alle VMs replizieren (15min, 1h, 3h Takt) um Worstcases abzufedern. Das Datacenter steht abseits der Firmeneinrichtungen aber im Aktionsbereich der LKW. Es wäre nicht vollkommen an den Haaren...

I would like to copy/replace the disk of a newly created VM with the one from a template using ssh command. The template's zfs vol is rpool/data/vm-100-disk-0 , How to copy this vol to VM ID 101 using ssh commands. Any tips ?

Hi, first of all thank you for the great software, we enjoy using it for more than a year now. Also sorry for any noob questions i will make. So we are using proxmox for our server without any problem and we are now thinking to make use of our old server as backup option. Our main goal is, in...

I have 2 nodes (rk1 and rk2) on each node I have an extra disk to create the zfs system on it, i have the latest version of proxmox and i have added the disks one to its node as ZFS and create a VM test and the vm disk i located is on the ZFS disk of rk1, when i go to make the replication it...

Hello, i have a cluster node ( ZFS / Replication /HA 3 nodes cluster ) with 3 VPS (2 LXC, 1 KVM ). All replication job on node2 are stalled but no errors log. Before reboot the node, i'm tryng a pve-zsync but return this error: /usr/sbin/pve-zsync sync --source 104 --dest...

Hi guys, I'm wondering how the data from a running VM replicated with consistence to another storage as I would expect some sort of guest interaction to trigger VSS for example to ensure there is no missing data due to writes being cached at the time the replication runs. I'm trying to compare...

Greetings I'm trying to run a replication between two nodes and get this weird error: 2018-12-28 17:17:01 141-0: start replication job 2018-12-28 17:17:01 141-0: guest => VM 141, running => 10901 2018-12-28 17:17:01 141-0: volumes => ct_A:vm-141-disk-1,ct_A:vm-141-state-After_install...

On my setup, a VM that takes 9.86T of ZFS pool on active host, grows to 19.6T when replicated to one of the other hosts. On yet another host, it takes 9.86T as expected. Every one of them has ZFS "copies=1" enabled. Data is already compressed (it's a nested zpool inside a zvol). The only thing...

Hello to all. I have used Proxmox since 3.4. the advances in the platform are definitely exciting to see! We are using zrep to sync zfs volumes to a non cluster machine at this time. Thanks to Brown @ bolthole for his code. It works well. However I have a hankering to use the cluster features to...

I do not understand what has happened, I have 3 hosts. all 3 running same version 5.0.23. All 3 on ZFS. Replication worked fin for a while accross the hard drives of one host to the other, but now it is stuck on 2 of the hosts. In the images attached, == vm1 no longer exists, it was...

Hi there, Consider a 3 node setup with each node having 2x 10GB & 6x 1GB Nic. Is it more interesting to speedup replication between the nodes using 10GB interconnects and have the VM's communicate on 1GB (scenario 1) or is it more interesting to speed up VM <—> desktop access (scenario 2) My...
