Hello all, I wanted to ask here for your experiences running PVE with local storage using ZFS on HP gen9 or gen10 servers. In near future i am planning to deploy two PVE installs on such two servers. I plan to use RAID1 (mirror) for boot drives and RAID6 (RAIDZ2) for data drives. I'm familiar...

Hello e100, thank you for your very informative reply. Do I get it right that your VMs are Linux machines (as you talk about OOMs in VMs)? I have Windows VMs, but I think that does not matter for this topic. I will use your examples as a starting point to dig deeper into virtual memory (vm.*)...

Thank you for your reply, e100! For some reason I am bit scared to run without swap, just don't want to let kernel kill my VM because he thinks it is good candidate to free up memory when needed. But I will give it a try... What is your experience with such setup, how do you provision RAM, do...

I am not sure if swapping can ocur under memory pressure on NUMA nodes, because those cluster nodes (hosts) are in fact 2 CPU NUMA nodes each with 48GB RAM... To Andrew: Well I am not able to turn off swap with *swapoff -a*. It never releases those few remaining megabytes and the command never...

Hello all, I think this is neverending question, but sometimes I'm facing swapping issue that I really do not undesrtand. I have two hosts in cluster (not HA), both running 96G of RAM. I keep enough of free RAM on each to be able to migrate all of VMs to one or other if needed, so total...

Well backup and restore method is not the best one, transffering (TiBs of) data twice is just waste of time and bandwith, but looks like there is no other way, so I will have to go through that :o). Anyway thank you for your reply. It helped me a lot.

Hello, the procedure of removing node from a cluster is clear for me, but I wanted to ask if it is safe to reinstall removed node and assign it the same name and the same IP that it previously had? I have some standalone PVE node that I want to move VMs to other nodes at existing cluster, so I...

I see, but memory usage dropped (see the graphs) when backup started... Well I am assuming that those graphs show host's overall memory usage. As the ARC cache warmed up next day the memory usage returned back to the previous numbers...

Okay, that's not the best news (SSD will be (slowly) worn out by buckups), but okay. I'm glad to know how things works. LXC is full of pros/cons needed to be considered when designing stuff. Good to know. Thank you for answers!

I'm just curious if the backup data are passing thru the tmp dir when backing up - just in case my tmp is on SSD, would it wear my drive out by backups?

Great, that did the trick (EDIT: Yes, backup target is on NFS storage). May I ask why the tmpdir is needed for the backup? And is the unprivileged LXC cause of the problem? Thank you.

Hello everyone, I've created and set up my first unprivileged LXC container, everything was okay until I've run into problems with backing up this LXC. The backup is failing with this error: ERROR: Backup of VM 320 failed - command 'set -o pipefail && lxc-usernsexec -m u:0:100000:65536 -m...

Hello, I'm wondering why when vzdump starts (once overy week), that it suddenly empties ZFS ARC cache. If you take a look at the graphs you see increase in CPU utilization (vzdump starts using pigz) and on the same time there is steady memory usage drop, which corresponds to lowering ARC memory...

Context menu: yes, I have it. Tried now, running in Chrome with "disable cache" in DevTools, no change. Tested in Chrome and even in Chrome canary now, still nothing.

Client OS is Windows 10 (build 1803). proxmox-mailgateway: 5.1-1 (API: 5.1-2/0b56b766, running kernel: 4.15.18-5-pve) pmg-api: 5.1-2 pmg-gui: 1.0-42 proxmox-spamassassin: 3.4.2-1 proxmox-widget-toolkit: 1.0-20 pve-kernel-4.15.18-4-pve: 4.15.18-23 pve-kernel-4.13.16-3-pve: 4.13.16-49...

Heh... Funny to read this (the way you ask and the way Proxmox staff replies). Either buy subscription and you will get "official stable" channel or just use free no-subscription repository on your own. I've never had a problem with no-subscription repository (PMG nor PVE) in the production...

Sorry for late reply, I was waiting for quarantine to fill up. Delete key does not work for me, I am using PMG 5.1-2, browser is Chrome. PMG is installed on top of Debian and running as LXC in PVE. Pressing delete key on selected mails in quarantine does nothing. pmg-api/5.1-2/0b56b766...

What is the key? Delete? I've tested it few moments ago and it did not work for me. Right click is okay, but the same with "wrong action triggered sometimes" applies here, these two options are too close to each other in the context menu.

When I am handling quarantine emails in a bulk it is quite irritating that I need to use mouse to trigger delete or deliver actions. It is already possible and very convinient to mark multiple emails using shift+arrows and I am using it a lot. Sometimes I even hit the wrong action (deliver...

Great news, great update, thank you.
