UdoB replied to the thread ZFS SSD Migration Consumer zu Server SSD.Ich habe einfach zunächst die dritte SSD wie in https://pve.proxmox.com/pve-docs/pve-admin-guide.html#sysadmin_zfs_change_failed_dev beschrieben angeklebt. Nach diesem ersten Zwischenschritt (vor dem Wiederholen mit dem vierten Device) hat man... -
UdoB replied to the thread Computer shutting down every morning around 3 that I didn't set to happen..The first thing is to look into the journal: journalctl -b -1 -e = show the end (-e) of the previous (-1) boot. Good luck then. Learning by doing is fine! Just try to understand what you are doing... ;-)

Like.
Sorry, I misunderstood. In that case you can leave it. Sure. So Proxmox uses the good default of 16k volblocksize. That means that all your VMs ZFS raw disks, are offered 16k blocks. Now lets look how ZFS provides 16k blocks. You have RAIDZ1... -

Nonsense. Displaying and alerting on (if a temperature gets higher than a set treshhold ) Temperature is one part of monitoring as well as displaying and alerting on CPU load, RAM or storage usage. And the funny thing is if you don't want to get...

Die haben auch eine eigene Wikiseite im Proxmoxwiki: https://pve.proxmox.com/wiki/Zram#Alternative_Setup_using_zram-tools Und wären generell auch meine Empfehlung, auch wenn man natürlich keine Wunder erwarten sollte. Sie kosten dabei aber auch...

Dieser Standardwert ist auch nicht mehr unbedingt 50%: Zum einen weil seit PVE 8.4 ( oder früher, aber irgendwann zu einer PVE8-Version) der Intaller von ProxmoxVE bei der Installation den ARC -Cache auf 10% (und maximal 16GB) des zu dem...

UdoB reacted to Johannes S's post in the thread HP Elitedesk 800 G6, welche SSD für VM, Backups, Proxmox? with Like.
Das Backup sollte IMMER außerhalb der Produktionshardware sein nach der 3-2-1-Regel: Drei Kopien, davon zwei auf verschiedenen Medien, eine davon an einen anderen Standort (Cloud, Freund, Familienmitglied). Siehe auch...

Zu Backup, jedes Backup ist besser, wie keines! Also bitte mal 2 HDDs/ SSDs anschaffen und als Medien nutzen.

UdoB reacted to meyergru's post in the thread ZFS storage is very full, we would like to increase the space but... with Like.
Obviously, I meant "not in a sensible way" - at least for what the OP asked for, namely to increase his storage from 2x the size of one of his physical disks, so using 5 disks either does not use one of them, thus not increasing the net size...

UdoB reacted to meyergru's post in the thread ZFS storage is very full, we would like to increase the space but... with Like.
A raid mirror usually has the read and write performance of a single disk (for a single thread - it can perform better with more threads if the data is distributed over more than one disk per mirror side). A raidz1 can perform much better on...

UdoB replied to the thread ZFS spesial vdev and VM.From all of my own experience: yes! How large the effect is depends on your actual use case, of course. Writing (and reading) the actual data may be (nearly) as slow as before - but the meta data can be read and written much, much faster than...

UdoB reacted to fba's post in the thread 40 node prod cluster restarts when joining a new node or removing. with Like.
There is some documentation available for Corosync network setup: https://pve.proxmox.com/wiki/Cluster_Manager#pvecm_cluster_network Using bonds is not advised, shared links with other traffic types are not advised too.

UdoB reacted to leesteken's post in the thread PVE 9.x cannot be installed from .iso image file with Like.
Try something else than Ventoy (as it is also know to cause problems) to create the USB: https://pve.proxmox.com/pve-docs/pve-admin-guide.html#installation_prepare_media

I just did this yesterday, using the Proxmox GUI. YMMV I suppose, but since I added the new drives first, what I did was: Out the OSD. This will start to rebalance in the background but all PGs remain blue or green. (blue I believe was due to...

Well like often the answer is: It depends :) Or to be more precise what workload are you planning to run, which downtimes/riscs you can live with and what tradeoffs you are willing to make. First: ZFS and Ceph both want to mange the discs...

Guide on how to use the CLI-based QEMU manager in Proxmox, which is named 'qm'. The guide covers everything you always wanted to know and were afraid to ask about managing QEMU/KVM and has a lot of tips you will not find anywhere else. As far as...
