    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...

    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...

    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...

    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...

    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.

    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...

    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...

    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 ...

    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...

    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...

    [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...

    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...

    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...
