Hi, yes thats a typo; meant the raidz1 - I thought, it might be worth a shot to go with 3 vdevs - 4 drives each in raidz1 - and those 3 vdevs striped. If needing to reconfigure, we will have a backupserver so the pool could be re-created and then restore the vms to the new pool.

We bought a new server from HPE (Gen11) which is equiped with 12 nvme 1.92 TB Disks. Now I am asking myself wether to configure it for maximum diskspace - like 11x in a raidz5 plus 1 hostspare vs. IO-performance - something like 5striped vdevs à 2 disks in mirror config plus 2 hotspares. So...

Port of nic vmbr0 and vmbr0.48 were all up, nothing seen in the logs - I was already ready to use an older iso for setup but I just wanted to show the problem to one of my colleagues - and all of a sudden connectivity was restored - no fuckin idea why. Last thing i had tried before that is to...

Hello community, we have setup a dozen of pve so I got quite some experience. But on the last one I got puzzled as I setup from iso, do configure /etc/networking/intrfaces to our needs and everything works fine, so I configured the apt sources and updated the system. After a reboot i dont get...

Another question on ARM. I was asked by one of our devs if it would be possible to have a cortex-m33 guest. From looking at qemu-system-arm -cpu help ... cortex-m33 ... What would I need to change in vm-id.conf in order for it to boot successfully? I suspect arch is not aarch64 - what would I...

Edit to add the final version of the script - created by AI: #!/bin/bash LOGDIR="/var/log/rccmd" LOGFILE="${LOGDIR}/shutdown_rccmd.log" NODES=(1.2.3.4 1.2.3.5) HA_TIMEOUT=60 GRACE_SLEEP=5 # ensure log directory and file exist locally mkdir -p "${LOGDIR}" touch "${LOGFILE}" log() { echo...

Because of ha settings, I would like to ask what services would ideally be stopped, in order to issue a shutdown by an usv-triggered event. Could the bash skript look something like this? ssh root@1.2.3.4 "<systemctl stop pve-ha-lrm> && <systemctl stop pve-ha-crm> && <shutdown -hP now>" && ssh...

Thanks guys for clarification. After having activating subscription and modifying the repo settings, I was able to install said package and thus run an arm64 guest. Thanks for your valuable support.

Thanks - now that you mentioned it - as this server is foreseen for a subscription I did not add the no-subscription repo, and as the subscription is not yet activated - I am not in a actual state. Will try and test again as soon as the subscription is activated. After testing will change thread...

Are you sure? apt install pve-edk2-firmware-aarch64 Package pve-edk2-firmware-aarch64 is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source

The error message indicates that for enabling spice options you need to be root. Question: So it is not possible to assign the right to enable spice settings to an ldaps group to a role with certain priviledge?

Are there some instructions anywhere on howto provide own aarch64 OVMF firmware to work along with pve9 enterprise repository.

Thanks for your quick reply. In the no-subscription the mentioned package doesnt exist for pve9, right? So how could/would I install it anyway to use it with pve9, while all the rest will be in subscribed enterprise repo? Is it possible to build it from sources and if so - are there any...

With PVE 8 we were able to install the package: "pve-edk2-firmware-aarch64" and thus create and successfully boot an platform "-cpu cortex-a76" (aarch64 / arm64) guest. On our new pve9 server which is foreseen for production use and will thus get enterprise repository we do not have package...

I also had the problem that after replacing a PBS and reinstalling the changer/tape library which contains two drives I could not restore the content of the tapes - while there were error messages stating that the drive could not be loaded. Reading your coment and rotating the two drives0 and...

good point on allow zfs arc cache to grow. What I will try after the ram test-build, is expose the others servers zfs ssds as iscsi and then use it on the first node instead of the nfs approach, as its a 2node cluster. And the clusternetwork is established by a direct connection of the two nodes...

Great post Johannes, so at the moment I am waiting to get price for two 1TB ssds but to create a separate pool for this building vm. In the meantime I will do two additional tests: - mount the io-heavy source folders into ram as the server has significant amount of ram still free - then its a...

You are so right @Johannes S , thats what I start thinking too. I am trying to decide if 2 x 1TB mixed use SSDs for this server each around 1k bucks is worth it. Thing is - the guest vm building heavily has a size of 5 TB thus I am trying to figure out where all the io takes place to either...

Thanks guys - I also started thinking that a special device might be worth a try. A special device can improve the speed of a pool consisting of slow spinning harddisks with a lot of metadata changes. For example workloads that involve creating, updating or deleting a large number of files will...

I guess I have to learn a bit more about arc and slog as I falsely thought that it is some sort of cache which augments iops capability of the whole pool. Thanks for the linked post which seems a good starting point. I ll come back with questions if anything remains unclear.
