Hi @all,
we have a node with AMD EPYC 7343 running on 7.3-6 and tried to configure a VM with CPU Type "EPYC Milan". Unfortunately this does not work as I get at start of the VM the following error:
kvm: warning: host doesn't support requested feature: CPUID.07H:EBX.erms [bit 9]
kvm: warning...
Hi@all,
I do have a problem with my newly setup PBS with the performance of pools. We have two clusters with both 20 nodes. Every cluster is backing up to the PBS on a separate pool of 12 disks. The performance of the pools is quite bad in zfs. On our intial test with some windows software...
Hi, I configured in Datacenter/Backups a 20 node cluster to do backups to PBS. Unfortunately all the nodes start backing up at the same time, which causes a very high IO on the PBS and leads to timeouts of backups.
Any idea how to delay this or to setup that the nodes to the backups one by one...
Hi @ all,
yesterday we had a pretty weird behaviour of our 25 node cluster. I did two things that seem to broke the whole cluster.
1) Started a live zfs migration form a node with a 6.1-x version to a 6.2-x node.
2) Installed in the meantime a new node and added it to the cluster (cause I...
Hi all,
I was wondering if there are any compatibility issues with Proxmox 5.4-13 (kernel 4.15.18-20-pve) and the new Zen 2 architecture with the EPYC lineup.
Specifically the new EPYC 7402P.
Is somebody already using such a setup, and if so, are there any other issues?
Regards,
Andy
Hi @all,
I am facing actually a problem where I am not able to create a iscis-zfs disk because the "cfs lock" gets an timeout. The problem that "zfs list" takes very long on my iscis server, because it has a lot of writes.
Is it possible somehow to higher this wait-time so that we get no...
Hi@all,
I did tried to add a "reinstalled" node to a cluster with "pvecm add 10.1.1.1" what stopped in "waiting for quorum". As 15 nodes are allready runningn on that cluster, and this node which I wanted to add now, was already minutes before in that cluster, I think the problem was not...
Hi all,
can I pass all cores and threads to a Virtual Machine?
So that the machine has for example all 8 cores and all 16 threads of the node.
Purpose for this is licensing.
Thanks in advance for answering.

Hi @ all,
when trying to backup a VMs disk with pve-zsync that is located at a "ZFS over iscsi" storage, I am getting "ERROR: in path".
Is it possible that this does not work with "ZFS over iscsi" storages?

Hi everyone,
I have a problem with VM shutdowns, specificaly Windows Server 2016 VMs.
When I use the shutdown button in the Web UI, sometimes Server 2016 shuts down without issue, but other times Proxmox gets Error "TASK ERROR: VM quit/powerdown failed - got timeout".
After following this wiki...
Hi @ all,
I am expiriencing the problem that targetcli is not reloading the saved configuration in "/etc/rtslib-fb-target/saveconfig.json" after a reboot. So always after a reboot you need to do the command:
targetctl restore /etc/rtslib-fb-target/saveconfig.json
In the man page of targetcli...
Hi @ all,
I expirienced a total freez of an machine a few days ago. Only a reboot helped and then the machine was running again. I do have arrount 10 of the same machines which are running since an year without any problem, and now wondering what has caused the total freeze of this one machine...
Hello @ all,
I did tested now pve-zsync to make some backups on my new backup server but have problems with understanding the used space of the volume backup.
Here the config of the node:

Hi @ all,
is there a default "limit" value set in pve-zsync when I do not add the option "-limit"? Because the transfer somehow seems to be limited to 1GB, even if I did not setup lo "limit" option.
Regards
Hi @ all,
I am asking myself when a server really needs a restart after a "apt update & apt upgrade & apt dist-upgrade"?
For example having a server with version
pve-manager/5.3-5/97ae681d (running kernel: 4.15.18-9-pve)
Ok sure if I upgrade the kernel to the newest "4.15.18-10-pve" I would...
Hi @ all,
I am experimenting with KVM Linux Guests (Debian) and asking myself if it really makes sense to have Linux guest OS use Page Cache at all? Because, as I understand, ARC should do the exactly same stuff directly on the node, right?
But how to disable it at all in the guest, as sysctl...
Hello @ all,
I am wondering if it is really nececerry to use block-level copying on "qm migrate --online --with-local-disks"?
Because having volumes with 400GB for example and only a couple of gigs are used inside (thin provisioning), takes of course long to copy on block-level instead copying...
Hello @ all,
we are experimenting with the zfs live migration and have recognized that the migration to another node, will delete all the existing pve-zsync zfs snapshots. So that on the next backup pve-zsync will fail.
Any idea if there is a option to kepp the snapshots on live migration...
Hello@all, I would like to do a
root@sendserver:~# zfs send rpool/data/vm-100-disk-0 | ssh recvserver zfs recv rpool/data/vm-100-disk-0
But i need to run that from the receiver site, so I tried
root@recserver:~# zfs recv rpool/data/vm-100-disk-0 | ssh sendserver zfs send...
Hi @ all,
we are planning actually our new Proxmox Servers and therefore think about the best performing and cost efficient setup.
Now we are a bit stuck at using ZIL and L2ARC on separate devices.
Here our actual planed setup:
Xeon 6134 Gold
254GB ECC DDR4 RAM
2 x 60GB SSD SATA - mdadm Raid...
