Hi, I have a container, hosted with PM on ZFS (compression on) and multiple disks. I want to import this with pct and define new disk size for each of his disks. If there is one disk, command would look something like: pct restore 212 nfsAKlocalDir:backup/vzdump-lxc-xxxx.tar.zst --storage...

Hi guys, just wanted to let you know, that with PM 7, when you plug in brand new Samsung pm9a3 MZQL21T9HCJR-00A07, one of the current disks dissapears (and so on with each disk you add). If you notice before your zfs raid falls apart, you can get old devices back with rescan of pci: echo 1 >...

Hi guys. I have upgraded my cluster from PM6 to PM7.3-4. Versioning: pve-manager/7.3-4/d69b70d4 and Linux 5.15.83-1-pve. I observed that live migration does work only from older CPUs (like E5-2690 v2) to new ones (like Gold 6154) but not the other way around. When migration fails, the VM...

Hi, on a server where PBS 1 was installed first, then PM 6, i want to change from bios boot to EFI, so I can finally enable ZFS features. I have proper partitions and everything, but then, when I run proxmox-boot-tool, it just does not create EFI files on EFI partition. How to force...

Hi guys, I have had a cluster of ProxMox on version 6 as well as PBS installed quite some time ago. We use ZFS for everything. I recently added new nodes and upgraded everything,.. PM to 7 latest as well as PBS. When ProxMox nodes were upgraded, there were no issues. As soon as I upgraded...

Hi guys, I just got some Samsung PM943 1.92 TB NVMe drives. Will install latest PM on them with ZFS in RAID 10. Now I wonder, should I use ashift 13 when creating ZFS pool and then 8k block size when defining storage in PM or..? I guess people can answer faster than I can do benchmarks, ...

Hi, after conversion of LXC to KVM which works, i have black screen / VNC console until I switch to tty1 with ctrl+alt+f1. Any ideas how to fix this, so that KVM 16.04 ubuntu based will start at tty1? I also just noticed, that when I use console for text input, it does not work. Picture shows...

Hi guys, I understand and always join an empty node to the cluster. But now I want to create cluster from one server which already contains VMs and is in production. Can the first node, the one you create cluster on, also contain VMs? If not, then I have to install new node, create a cluster...

Hi guys, does PM 6 work with PBS 2? I wonder if I should upgrade PBS from 1.1 to 2.*. It is used bt PM 6 cluster, fully updated. Have no plans for upgrade PM 6 to 7 a.t.m.

I monitor all services listed in PVE HTTP GUI under System: After upgrade from 6 to 7 i got notifications about chrony not running. I installed chrony (replaced systemd-timesyncd) but now systemd-timesyncd failure is triggering monitoring system. As both can not run at the same time, I wonder...

Hi, since we have installed ifupdown2 we can apply network configuration without restarting the host. What would the manual equivalent of this apply button be in shell? I tried ifdown vmbr0 && ifup vmbr0 and all VMs instances network cards were removed from the bridge and lost connectivity.

Hi guys, ever since I have encountered a crash, because ZFS did not release ARC memory fast enough, I limit it's use to a number I know will always be available and will not be requested by other processes. I am wondering, is it safe now-a-days not to define maximum ARC size and ARC will...

Hi, on some network cards, vlans do _not_ work, unless I disable vlan aware bridge option. Because it always works, if I disable it, and I'm tired of testing this over and over, I wonder are there any downsides to not making bridge vlan aware and let PM create new bridge for every vlan. Do you...

Hi, when using PBS I noticed, that because of no dirty map for shut down VMs, PBS or PM vzdump does read whole VM to notice, that there are no changes. For shut down VMs with big disks, this means whole lot of disk reading for nothing. I would suggest, that a feature be implemented, that would...

If I want to backup a template from the template server to PBS, the backup fails, because the template has too many cpus defined. This makes sense only if you want to run the VM, not if you want to backup it. My template node obviously has less CPUs than compute nodes, but my templates are used...

Hi, a coworker made a network loop for 60 seconds and it turned out that some PM cluster which uses WAN side for clustering rebooted itself - all nodes. It made me wonder, can network loop cause PM to reboot itself? Will it reboot, even if no HA resources are defined on cluster? Under what...

HI, it took me some time, but I finally understood that is going on. Before I open bugs on bugzilla, I want to make sure I get things right. 1. BUG: Proxmox docs state, that PM 6 cluster does not require multicast. "Note: Proxmox VE 6.0 uses corosync 3 which switched out the underlying...

Hi, i did what I did many times before. Added a node to existing cluster. After adding it, whole cluster went down (VMs were running but PVE stopped). Here is how it looked on one node: [Fri Jan 29 14:46:36 2021] INFO: task pvesr:42198 blocked for more than 120 seconds. [Fri Jan 29 14:46:36...

Hi guys, a few days ago, I did backup import onto HDD pool on the same server that also has SSD pool. After a few minutes all guest VMs (they run only on SSD pool) started reporting problems with hung tasks, etc and services on them stopped working. Host has had high IOWait and low CPU usage...

Hi, i noticed that my two of my backup VMs use internally less space than is seen on hipervizor. Here is an example. Inside VM: /dev/sdb 4.0T 1.8T 2.2T 44% /backup Outside VM: rpool/data/vm-140-disk-1 2.70T 1.58T 2.70T - VOLSIZE LUSED USED...
