UdoB replied to the thread Storage performance IOps difference.No ;-) You posted twice. And I wanted to give a potential reader/replier a chance to realize this before writing an answer which has possibly already been answered over there... -

Like.
Thanks for your input, Johannes S. This is exactly why we are testing as much possibilities as we can. And, at the moment, we are learning very much every day. In the past we would have installed a small VMWare cluster with shared storage... -
UdoB replied to the thread Use Disk PassThrough or Raid-0 for PVE with Ceph (Testsystem).This! It's great to have choices. To make a good decision you need to know the disadvantages in beforehand and in detail.

UdoB reacted to Johannes S's post in the thread Use Disk PassThrough or Raid-0 for PVE with Ceph (Testsystem) with Like.
It depends on your usecase. If you want to have still a working cluster if two nodes get down (due to maintenance or failure) you will need more than three nodes for the reasons Udo explained in his writeup. But if you are fine with just being...

SSorry for my English. It seems to have been resolved, it was an x-systemd.automount inserted in fstab, a USB disk that was no longer working. This seems to have saturated the processes and prevented The login and trusted communication between...

These basically show similar things to zpool status and zfs list. RAIDZ has padding overhead and the GUI also mixes different units (TB vs TiB) and that's where the discrepancy comes from. This was talked about here: -...

That is why everybody will recommend you to use mirrors for blockstorage hypervisors and not RAIDZ. RAIDZ can be good for files, but is not good for block storage. Short overview on how this works: 4k secotor size is the default. So you will...

UdoB reacted to Johannes S's post in the thread Feedback: lack of host backup has me reconsidering use of Proxmox with Like.
You can backup the host the same way like any Linux Server with the backup tool of your choice. I use restic + resticprofile but any backup tool for Linux will do since in the end Proxmox products are customized Debian. Now if you prefer to use a...

UdoB replied to the thread Is there a NON-host way to automate zfs dataset snapshot creation?.Never used it with this option in my mind. Although I thankfully recognized that I only need one instance of that script per cluster, so obviously it integrates into PVE :-)

UdoB reacted to Impact's post in the thread Is there a NON-host way to automate zfs dataset snapshot creation? with Like.
cv4pve-autosnap works via the PVE API so it can run inside a CT or wherever else as well.

Please don't. Systems without security Updates ( due to being EOL ) belong in Museums not in production. Can you post more Details on your Systems please? Especially the vm config and storage hardware

UdoB replied to the thread Connection error 596.Purely guessing: it may be an IP address conflict. Triple check if the IP addresses of all devices are the same as before.
-
UdoB replied to the thread Is there a NON-host way to automate zfs dataset snapshot creation?."cv4pve" needs direct access to the ZFS pool and for this reason it is installed on the host. "Zamba" is a normal PVE container, just consuming storage via mount-points - which is absolutely usual and documented. -->...

Fehler ist behoben, Neustart des neu installierten Node hat geholfen. Danke!

UdoB reacted to woma's post in the thread [SOLVED] ZFS Pool nach update vom 8 auf 9 nicht mehr für neuen VMs nutzbar? with Like.
Ok, dann nehme ich das wieder zurück. Ich habe aber irgendwas abgespeichert, dass man PVE Hostnamen besser überall klein schreiben soll, weil sonst irgendwas nicht mehr funktioniert. Komme aber nicht mehr darauf wo das ein Problem war.

UdoB replied to the thread [SOLVED] ZFS Pool nach update vom 8 auf 9 nicht mehr für neuen VMs nutzbar?.Nein, eher nicht. Die aktuelle ZFS Version unterstützt Fähigkeiten, die bei dir noch nicht "freigeschaltet" worden sind. Du kanst das erstmal ignorieren. Überprüfe noch einmal die Konfiguration in /etc/pve/storage.cfg . Für einen normalen Pool...

UdoB reacted to a.woll's post in the thread [SOLVED] Nach Update auf v9.0.7 UI zerschossen. Ich bitte um Hilfe. with Like.
Ich habe den Fehler beheben können. Aus unbekanntem Grund fehlte nach dem Update der dbus.service. Kaum neu installiert, funktioniert es wieder.
