Hi, Weird behavior for a Ubuntu Server 24.04 VM. Download speed ~500 kbps While a debian 12 VM is able to download at full speed 1000 Mbps. On PVE host no bandwidth issue, firewall on (nftables), masquarade, ipv4 forwarding activated. VMs use CPU type = host with numa activated as well...

Hi, I plan to build a new proxmox ceph cluster (3 nodes). LACP 2x25 Gbps for ceph LACP 2x10 Gbps for VMs My question is related to the switches, I want mlag switches indeed. Mikrotik was my first choice due to functionalities and low budget as well. I have 2 CRS310 and have settled a very...

Hi, I usually buy FS modules and these modules work as expected despite low costs. I'm wondering if you guys also use FS switches, 25Gb+ models with mlag. Well known network brands are very (to much) expensive these days ! Pro/cons appreciated ! Thanks !

Hi, I plan to renew servers in order to build a 5 nodes Ceph PVE cluster. I read some topics related to NICs, some users choose to switch to 100 Gb. I was about to buy 2 nics cards with 2x25Gb each per server and split them like this : - LACP 2x25 Gb for vmbr0 - LACP 2x25 Gb for Ceph...

Hi, I have lots of old Dual CPUs Intel servers and I plan to renew them. Seems that AMD Epyc are now competitive (costs and performance). What I'm about to build : 4 x Supermicro nodes, with per node : 1 x AMD Epyc 9534 (64 cores/128 threads) 512 GB RAM 2 basic SSD with RAID1 for OS 4 nvme...

Hi, My 2 synchronized PBS have a ZFS datastore which is 80% full disk space. several hundreds of VMs and the issue is that when a VM is not backuped anymore, snapshots stay on the datastore forever. We have to manually delete groups one by one... So I'm wondering if I could purge an entire...

Hi, I'm wondering if there is any reason why amd64-microcode and intel-microcode are not installed by default. Installing these packages is something you recommand ?

Hi, Is there a way to delete/remove snapshots older than X days (or specific date) in one shot ? Thanks

Hi, Instead of manually deleting old backups 1 by 1 (because for example vm/ ct doesn't exist anymore), is there a way to remove all backups that had been created before specific datetime ? Thanks ! Antoine

Hi, I noticed that during a PBS backup of a large MySQL VM (with guest agent installed), Mysql is not able to perform requests (select, update, insert)... I thought that the FS lock triggered by qemu-ga guest-fsfreeze takes only few seconds in order to have a consistent FS. Is it the normal...

Hi, I have recently replaced all my HDD for 10 SSD for my ZFS Datastore. This is now extremely fast specially verify jobs (even if we can discuss the interest of verifying snapshots on a ZFS pool). The weird thing is that PBS reports fragmentation on the related pool : AFAIK, on a SSD...

Hi, Seems that latest pve7.1 changes the way we record totp on /etc/pve/priv/tfa.cfg. I have a problem with that because the 'Secret' is now showed V2 : V1: V2 method allows root to know all secrets keys for all users. Some of them use the same TOTP secret for several services...

Hi, We usually make KVM VMs. But for history reasons we still have some old containers. Openvz containers which were migrated to lxc since PVE4. Now with pve7 some LXCs refuse to start properly (mainly due to old systemd < 232). Also, LXC live migration is impossible. So I'm wondering if...

Hi, I tried to upgrade a 6 nodes pve7 cluster yesterday. We use Ceph and HA for all VMs. I was able to upgrade 4 nodes without issue. But on the fifth node, I lost the whole cluster. All nodes rebooted ! Syslogs for nodes 22 to 27 : update ok for nodes 22,23,24 and 27 upgrade of node 25...

Hi, Yesterday an updated PVE7 node crashed - Dell R440 - Xeon(R) Silver 4210 CPU @ 2.20GHz (2 Sockets) with 256 GB RAM The weird thing is that network was still OK - and corosync said that all 6 nodes are reachable. the GUI showed involved node grayed - its Vms continue to respond to ping...

Hi, I recently upgraded a 6 nodes Ceph PVE cluster 6.4 to 7 We discovered higher CPU usage, performance issues. I want to recreate all cluster. What I plan to do for each node : - Migrate all VM to another node - Stop all OSD and then remove them from config - shutdown the node. - remove...

Hi, I recently upgraded a 6 nodes PVE cluster to PVE7 cat /sys/devices/system/cpu/cpu2/cpufreq/scaling_governor performance Users report me some issues (lag, freezed browsers for 1 min) for several LAMP VMs... Everything seems to be ok inside the VMs including pve nodes ressources... I'm...

Hi, Is doing 'Verify Jobs' makes sense on a fully ZFS datastore ? Thanks in advance !

Hi, I plan to upgrade a switch stack (2 switches) which means a downtime of 5 min (or more) I guess. 6 PVE Ceph nodes are connected to this stack, with nearly 80 KVM VMs in HA. Even with shutting down all VM for 10 min, I think that PVE nodes would reboot, and I don't what could be the...

Hi, I recently noticed that my debian 10 VMs reports high disk usage (80-100%) with atop. Here are some screenshots for the same vm (completely idle) ran by several pve kernels Kernel 5.4.114 Kernel 5.4.106 Kernel 5.4.73 any ideas ? Running some basics 'dd' tests writes inside the vm...
