Due to the ipv4 shortage, especially in my case the new https://docs.hetzner.com/general/others/ipv4-pricing/, needs to find saving setups. Let’s say I got ip1 and ip2 statically routed to proxmox node. I would need to separate services like this ( instead of using 6 different ips): Ip1:443...

According to https://pve.proxmox.com/wiki/Storage_Replication#_supported_storage_types, currently only ZFS is supported. I'm aware that Storage replication requires a unique set of features for the storage ( like snapshots, send/receive remote, etc). What is your roadmap for adding other...

For performance reasons, instead of mounting with discard option inside KVM, it's better running external fstrim command via qemu-guest-agent, on host cron event. However, discard=on must be setup in KVM storage configuration at /etc/pve/qemu-server/VMid.conf Default mode is sending mail to...

Usually, all the lvm snapshots for a VM are removed on VM deletion. But, during some benchmarks, I needed to create more than 100 snapshots for a VM. This time, all the snapshots remained intact, despite deletion of the VM ( this is valid for several VMs). root@melania:/etc/pve/qemu-server#...

The error shows up at https://MyServerAddress.com:8007/#pbsServerAdministration:tasks, during KVM restore. … 2020-09-23T00:39:06+03:00: GET /chunk 2020-09-23T00:39:06+03:00: download chunk "/ab/store_melania/.chunks/7b76/7b76c3f2a082015fbf28719166b4e470def1063339f653b9dfb5892b71917f03"...

According to https://pbs.proxmox.com/docs/administration-guide.html#restoring-data, first check root@rise1rbx:~# proxmox-backup-client restore vm/100/2020-07-16T09:52:09Z index.json - { "backup-id": "100", "backup-time": 1594893129, "backup-type": "vm", "files": [ {...

The use case is a production Proxmox server sending incremental backups via pbs to a remote datastore on another Proxmox backup server. The other Proxmox backup server would act as a hot standby ( couldn’t be as synchronized as https://pve.proxmox.com/wiki/Storage_Replication, due to longer...

For virtual machines incremental is very fast ( based on QEMU dirty bitmaps, a matter of seconds) . For LXC containers, it seems that there isn't any incremental implementation... LVM- Thin storage, backup mode snapshot 1) initial backup INFO: starting new backup job: vzdump 104 --node...

There are plenty of post forum with this kind of error, usually triggered by wrong configuration of /etc/hosts https://pve.proxmox.com/wiki/Install_Proxmox_VE_on_Debian_Buster#Add_an_.2Fetc.2Fhosts_entry_for_your_IP_address or network Mine seems to be correct: root@lon:~# cat /etc/hosts...

My use case is described here https://lwn.net/Articles/442355/, for containers with checksum integrity, because I can’t use the qemu workaround cache=writethrough . Directly setting parameters like max_ratio or read_ahead_kb ( see...

Are there any API Clients for Proxmox Mail Gateway? Or we have to fork from https://pve.proxmox.com/wiki/Proxmox_VE_API#Clients ? Thx!

For the sake of simplicity, I shall build the post, based on https://www.modulesgarden.com/products/whmcs/proxmox-vps example. Normally, this should be posted in https://www.forum.modulesgarden.com/, but the discussion is more general, regarding the security of any third party application...

According to https://pve.proxmox.com/wiki/Firewall#pve_firewall_ip_aliases, user can overwrite local_network in the cluster.fw , in order for the firewall automatically sets up rules to allow everything needed for cluster communication (corosync, API, SSH) using this alias. What about...

The problem Problems with "two_node" Clusters This corosync options depends on a fence race condition, and only works using reliable HW fence devices. Above 'self fencing' algorithm does not work if you use this option! Via...

I wanted to test the efficiency of Ipfilter-net for container. Inside the container, after running the following command ( from https://sandilands.info/sgordon/address-spoofing-with-iptables-in-linux), spoofing the ip, all output network activity is blocked ( ping etc). iptables -t nat -A...

First of all, kudos to Wolfgang Bumiller for the “hot” summer btrfs patches. It surpassed my expectations, it really works, except several issues, perfectly normal for an experimental phase. Related proxmox forum posts...
