Maybe a stupid question, but I cannot find any hint in the documentation. Does PBS 2.x benefit in any way of a zfs pool vs. a hardware raid array? I'm not talking about general discussion regarding zfs vs. hw raid (both strategies have pros and cons, it's a long discussion), I'm interested...

A lot of (old) related posts in forum, let's see if something changed in 2021 :p Giving an HP MSA SAN, connected (Fiber Channel) to some HP servers, what will be the best solution to use SOME (not exclusively) of the SAN disk space with proxmox ? AFAIK, the recommended method is creating and...

Hello again! IIRC address of the first installed server in cluster is listed in the corosync.conf, totem section (actually more correct will be: the server where proxmox cluster was created). When that address will be used and how could be changed ? Because I will need to reinstall that server...

Hello! Two migration scenarios, source and destination servers are using local zfs storage, let's call it local-zfs. 1st scenario (with preparing): 1. set replication to destination, schedule manual replication, wait until completed - only used space is copied 2. migrate - will copy disk delta...

Hello By digging in the code I saw that is possible (but only from console) to use dns challenge with alias. The problem is that nsupdate runs as nobody/nogroup, and if you want to keep the dns key in a single place somewhere in /etc/pve/ it will be root:www-data, and no 0644 is possible (even...

Proxmox 5.x (updated to the full), when updating to kernel pve-kernel-4.15.18-30-pve / 4.15.18-58 older guest machines (debian <= 6) with virtio network driver became not accessible (not even ping). No message logged, nor in host, nor in guest, but ping just stops working. Kernel version in...

Topic: Proxmox 6.2 on ZFS (live migration included) on HPE Proliant servers. (Sorry for such a long post :-P ) ceph is not quite a solution, because it requires (or at least highly recommends) at least 10gigs network I have some older and some newer hp servers, like: - HP Proliant DL380 G6 /...

Hello I was just testing Proxmox 6.2 and I was wondering why only the second disk of the vm was transferred fully, and first one was just incremental (and the zvol was there). Well, actually it seems that I've just set a replication (from GUI) and forgot about it :p. But the question remains...

Prerequisites for this test scenario: - 3 VMs with 2 eth (first one configured), installed proxmox 5.4 on test1, test2, test3, updated to the latest packages versions - created cluster on test1 - test2 and test3 joined cluster through test1 - VM test4 installed with proxmox 6.0, latest updates...

Hi Generally speaking, I always prefer to reinstall than simply upgrading a server. Maybe it's more work to do but it's cleaner and "subtle differences" are avoided. But, if I understood correctly, it's not possible to upgrade a pmx5 cluster this way (foreach pmx5, move vms, remove server from...

Disclaimer: I'm not trying to start a religious war :-P As probably everyone knows, there is a generally "goodbye iptables (in fact netfilter), you served as well" fashion movement in the linux community. Redhat integrated nftables in their firewalld, Debian introduced nftables in latest buster...

Hello A strange (but possible normal) behavior when moving VMs or changing storage when using local LVM thin storage (online move, with vm running): - when moving a VM from a host to another (in particular, with multiple disks) qm migrate #ID #destination -migration_type insecure -online...

Hello I was using some scripts to create virtual machines. After latest updates on pve-storage packages qm create returns error when creating machines with more than one virtual disk on local-lvm storage. # /usr/sbin/qm create 101 --name test --ostype l26 --cpu cputype=host --sockets 4 --cores...

Hello I'm playing with some scripting stuff, but got into some issues. I'm trying to find out if a virtual machine with id $vmid already exists or not IN THE CLUSTER. The web interface stops me from creating virtual machines with duplicate ids, so the check is surely built in. Ideas: I could...

Hello Since the last update, all storages are listed in the dropboxes in web interface (mixed backups, iso, templates images, hard disk storage). i.e.: for cdrom iso images all storages are shown (including let's say lvm-thin storage), for hard disk images also all storages are shown. Before...
