Like.
Nein, ist er nicht. Mein "Auslagerungsstorage" ist auf einen anderen Server, für den man andere Zugangsdaten braucht. Außerdem kann der auch so konfiguriert werden, dass er für den primären PBS gar nicht erreichbar ist. Ich mache das aktuell... -
Hallo, das geht mit qm remote-migrate, siehe https://pve.proxmox.com/pve-docs/qm.1.html Falls die Doku nicht reicht, hier wäre noch ein Beispiel: https://www.thomas-krenn.com/en/wiki/Proxmox_Remote_Migration

UdoB reacted to ness1602's post in the thread Simple concept for manual, short term use failover without significant downtime? with Like.
You are literally speaking about snapshot replication, by zfs or any other FS. So just setup pve-zsync to another machine and it's done.

Is this just wishful thinking? Or is it a procedure you've verified, backed by evidence and proven results, that anyone would find convincing? I, for one, would not entrust my systems to the company that proposed this.

UdoB reacted to Kingneutron's post in the thread Raid1 boot array, drive replacement procedure with Like.
Forget btrfs and go with zfs mirror, it's supported in the installer and there is actual official doc on it. Tested and works. https://pve.proxmox.com/pve-docs/pve-admin-guide.html#sysadmin_zfs_change_failed_dev...

You confuse lxcs ( Linux containers) with lxd ( Software for managing vms and lxcs) Both lxd ( and it's fork incus) and ProxmoxVE manage vms and lxcs. Lxcs are more lightweight than vms but only work for Linux applications since they run directly...

UdoB reacted to Johannes S's post in the thread [SOLVED] auf gleichem PBS (v3) langsamen Storage zum langzeit Archivieren verwenden with Like.
Was? Das prunen geht eigentlich recht schnell. Die garbage-collection oder verify-Job werden bei hdds aber immer lange dauern, weil beim PBS der Datenbestand in zig kleine Dateien ( Chunks ) aufgeteilt wird und jeder (!) chunk dafür eingelesen...

UdoB reacted to Johannes S's post in the thread Cluster - Corosync - nur 1 nic - VLAN nutzen? with Like.
Grundsätzlich ist das ja auch keine falsche Annahme, da ja ZFS streng genommen kein echter shared Storage ist (eben weil man da immer einen Datenverlust hat). Aber wenn es für den eigenen Zweck reicht, stört das ja nicht ;)

UdoB replied to the thread SMTP notifications configured in PVE: no emails to root.No direct help but only a hint: you need to search for "setup Postfix with authentication on Debian" or similar. You will find a zillion articles; I have no specific one to recommend.

UdoB replied to the thread [SOLVED] auf gleichem PBS (v3) langsamen Storage zum langzeit Archivieren verwenden.Viele meiner Homelab-Mainboards erlauben das Datum-/Uhrzeit-gesteuerte Einschalten direkt per BIOS-Setting. Andere Kisten kann ich per WOL aufwecken, aus einer crontab heraus. (Oder per schaltbarer Steckdose, "klassisch" oder per "Smart Socket"...

UdoB replied to the thread What would cause a backup to not work, can I recover from this? [solved].Yeah, that's one of the manifold pitfalls everybody enjoys; glad you made it work again! There is only one countermeasure: exercise restore from time to time, not just run a backup ;-) There are situations where stop-mode is recommended, yes...

UdoB reacted to alia80's post in the thread [SOLVED] RAIDz2 zpool not showing full capacity after zpool attach with Like.
I moved a lot of data off the pool and used zfs rewrite to rewrite all the files hoping it would recover the reported capacity but none of it worked. The only interesting thing was that when I copied files to another pool the reported size of...

UdoB reacted to Impact's post in the thread How to set Swappiness permanent to 0 on Proxmox 9 with Like.
I wrote a little bit about SWAP monitoring here. If you use disk based SWAP anyways I'd recommend ZSWAP. Note that swapon is basically the "human readable" version of cat /proc/swaps and with sysctl vm.swappiness you don't have to use a pipe and...

UdoB reacted to LnxBil's post in the thread How to set Swappiness permanent to 0 on Proxmox 9 with Like.
What I don't see mentioned here is that just monitoring the swap usage is not as good as monitoring the swap in AND swap out activity. You want to monitor that, because if you only swap in stuff without reading it back soon, that is actually...

UdoB reacted to alexskysilk's post in the thread Simple concept for manual, short term use failover without significant downtime? with Like.
the relevant questions to ask: 1. Would you want the failover to occur automatically, or with user intervention? 2. What is an acceptable outage period? 3. What is acceptable in terms of minimum performance (specifically, disk performance) IF...

UdoB replied to the thread [SOLVED] Node is online but appears offline - this only happens if a node in the cluster goes down.Are you sure you know exactly what this does? I am sure, I do not ;-) My recommendation: return to a default setup, then it will react with the default behavior.

UdoB replied to the thread Simple concept for manual, short term use failover without significant downtime?.One very low-end approach, with these assumptions: you have two nearly identical PVE server, not clustered one is doing its job, the other is turned off you have sane PBS (with SSDs only, at least for the latest backup) - as you need to have...

How can you know this without trying? Nobody knows your requirements except you. It's the version 1 of the Datacenter Manager aka their equivalent of VSphere. It already allows migration of vms between different clusters or...
