  1. Question Pattern Replication Schedule

    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...
  2. Operational issues with ZFS and pvesr

    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...
  3. Bug bei replizieren

    Hi, ich habe testweise 2 Proxmox zu einem Cluster zusammengeschlossen. Beide sind mittels nativer ZFS-Encryption verschlüsselt. Wenn ich jetzt von Node A eine VM auf Node B Replizieren (in GUI Konfiguriert) möchte kommt im Log die Meldung: cannot send...
  4. [SOLVED] Replication not possible ? Cluster + ZFS

    Hi, I'm trying to do replication but it's not working, here's my setup. Cluster of 3 nodes. Local ZFS storage on each node. Each ZFS pool has to have a different pool name, this seems to be a consequence of each node being part of the cluster. When doing the replication it asks that the...

    hi there. I have 2 CPD in different buildings, connected with 10Gb Fibber, 1 is the production the 2 is the backup disaster recovery. how could I replicate every x time from production CPD VM to the Disaster Recovery CPD ? Both configuration is similar, 3 servers and 1 SAN storage. thank you !
  7. Online / Live Migration with ZFS-Replicated local VMs?

    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...
  8. Feature request: VM migration (restart mode)

    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...
  9. SSH between nodes and replication

    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...
  10. Host key verification failed

    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...
  11. Host was reset randomly

    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...
  12. ZFS Replication running away?

    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...
  13. ZFS snapshots and replication: Sufficient as backup?

    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...
  14. ZFS Quota vs. Refquota

    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...
  15. jmcorrea

    [SOLVED] FSTrim and Discard needed on ZFS?

    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...
  16. Kombination CEPH und Replication

    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...
  17. How to copy ZFS Vol

    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...
