Enterprise drives should not need manual trim so I never looked into it. However, I always trim the guests, but mainly due to thin provisioning reasons (discard). -

I recommend ZFS if possible. With this you can use replication as well making migration very fast and HA possible.

***** UPDATE ****** ... If anyone is interested ... i switch from using SNMP to using Glances... and just reading the web interface. The SNMP bases unit started to fluctuate the readings ... mainly on the CPU usage..... it would show 20-50% ...

UdoB replied to the thread Hardware Anfrage.Nein, niemals. Allerdings "hing" einer von vieren mehrfach. Der hat nun eine andere Aufgabe... PS: du zitierst in #5 drei verschiedene Nutzer, wie kommt es, dass "Username: " fehlt? Wenn du jeweils den zu zitierenden Test markierst und dann...

UdoB reacted to Kingneutron's post in the thread Proxmox 9.1 and extremely slow disk performance with
Like.
Proxmox is not Vmware. ( This is sometimes a surprise to homelabbers. ) Vmware ESXI may be more "forgiving" of cheap media, but you pay their licensing fees for the privilege. Proxmox community wisdom has determined that Crucial BX drives are... -
UdoB reacted to news's post in the thread Proxmox 9.1 and extremely slow disk performance with Like.
The Crucial BX500 SSDs my be faster with a new disk and will slow down after usage. QLC mean the SSD Flash must store 4 Bit at once. Proxmox VE Version 9 is based on debian 13, so check the Internet about your Hardware and debian 13. Maybe you...

Heres a pic on the ESP32 with the old lcd and the Ardunio C Code. I'll post the scripts in another post #include <WiFi.h> // ESP32 Core WiFi Library #include <WiFiUdp.h> #include <Arduino_SNMP_Manager.h> #include <Wire.h> #include...

UdoB replied to the thread New to Proxmox.For Ceph you need to have at least three nodes, better five or more. Some hints: https://forum.proxmox.com/threads/fabu-can-i-use-ceph-in-a-_very_-small-cluster.159671/

UdoB replied to the thread [SOLVED] Configuration help with multiple nics.You can have only one DEFAULT gateway! Everything more complex needs either a "real" router or at least some additional "ip route"-magic.

UdoB replied to the thread Hardware Anfrage.Ich hatte (und habe) ebenfalls HM80. Die habe ich teilweise durch "Manufacturer: ASRock Product Name: X600-ITX" aka "DeskMeet X600" ersetzt. Insbesondere, weil die Dinger 128 GiB Ram vertragen und Platz für je zwei SSD+NVMe bieten. Die...

With SMR drives (or QLC SSD), I would expect write errors (due to timeouts caused by the bad performance). The checksum errors suggest that there is another issue like cables (as already mentioned), controllers or even memory (but unlikely with...

UdoB reacted to spirit's post in the thread new install, cannot create Ceph OSDs bc of keyring error with Like.
Hi, I have same problem than you (trying to create 2 osd by nvme, as currently gui is missing this feature) simply: ceph auth get client.bootstrap-osd > /var/lib/ceph/bootstrap-osd/ceph.keyring to generate the keyring at the correct location.

Hi there It looks like the issue isn’t the SSD itself but the ZFS label on one of the rpool members. The key part of your zpool status output is: status: One or more devices could not be used because the label is missing or invalid. ...

UdoB replied to the thread PBS Limited to 1Gb.RaidZ2 (in this context) is... crazy - or at least "suboptimal". PBS needs IOPS as it handles your large amount of data in (max) 4 MiB chunks. (This has been discussed multiple times.) It would be better to go for six mirrors - you would get...

UdoB replied to the thread ZFS Pool Errors/high IO delay.I would like to add: whatever you do with rotating rust in the PVE context: add a fast "Special Device", using two mirrored SSD or NVMe.

You can replace "bad" drives, so by 4 new one: Because *) Seagate ST8000DM004 8 TB store data with SMR (Shingled Magnetic Recording), that's very bad! Only use CMR Drives from Seagate NAS Pro Change all your SATA III cable, buy new one and...

UdoB reacted to news's post in the thread Hardware Empfehlung für ersten Homeserver - Terramaster vs. DIY with Like.
Das sehe ich anderes ZFS funktioniert problemlos auch ohne ECC Ram, aber die Vorteile einfach seinen ZFS Pool managen zu können, hat man mit LVM, ext4 nicht. Dann erhält man durch ein passendes Setup als ZFS Pool mit 4x HDDs (vdev0 zfs mirror...

First, upgrade. I've had high load on empty / low use PVEs before on HPE servers, until I upgraded to 9.0. We're now at 9.1, upgrade. You version is more than 1.5y old, a LOT has been fixed and improved since. If this is a production system of...

Grundsätzlich würde ich dir empfehlen vor der ganzen Aktion backups sämtlicher VMs und Container zu erstellen und das upgrade samt restore n einer neuen vm zu testen. Das geht auch für verschiedene Szenarien (Neuinstallation+restore oder upgrade...
