UdoB replied to the thread Just can not get IP to work.The usual approach for a small box with a single NIC is this: https://pve.proxmox.com/pve-docs/pve-admin-guide.html#_default_configuration_using_a_bridge If your setup differs then you need to describe the differences in detail - to allow... -
UdoB reacted to Johannes S's post in the thread [TUTORIAL] HiveStation - Developer Workstation for Proxmox Virtual Environment with
Like.
Regarding swap following posts by Kernel developer Chris Down are worth a read: https://chrisdown.name/2018/01/02/in-defence-of-swap.html https://chrisdown.name/2026/03/24/zswap-vs-zram-when-to-use-what.html The basic gist is that even if you... -
UdoB reacted to lubosr's post in the thread [PBS 4.2.5] Datastore > Content: Bulk Change Owner in GUI? with Like.
Not in the GUI, no. I checked on 4.2.5 and it is still one group at a time. The Content list is a tree (namespace, group, snapshot, file) rather than a grid with checkboxes, so there is no multi-select for a bulk action to hang off...

50% is fine. This size is just the max size, it isn't reserving 50% of ram in case you write a file to /tmp, it will use memory for files as they are written, and free the memory again when they are deleted. The size is the limit where the...

UdoB reacted to tcabernoch's post in the thread PBS InfluxDB2/Grafana External Metric Server with Like.
My boss had me setup the Proxmox Metric Server feature to see if that would help provide backup reports to client. Spoiler alert: No. PBS External Metric Server feature does not provide Backup reporting info. (Any suggestions for providing...

Proxmox Backup Server is the answer, if you want to use other backup software, please ask in their respective forums. It is also highly advised to use a Proxmox consultant for commercial best practices which also helps with implementation...

UdoB replied to the thread DC and DR Setup.This is for a commercial setup, right? And you are starting from scratch, without much experience, right? If both is true you need either an external consultant (as @LnxBil already mentioned) or a lot of time. You mentioned "DR", Desaster...

By using a hook script, you can automatically perform a rollback only when the VM shuts down. mkdir -p /var/lib/vz/snippets cat << 'EOF' > /var/lib/vz/snippets/shutdown_rollback.sh #!/bin/bash if [ "$2" = "post-stop" ]; then ( sleep...

UdoB reacted to LnxBil's post in the thread 9.2 ISO verification, and best practices security wise with Like.
The signature file contains two signatures, one from bookworm and one from trixie: $ gpg --list-packets proxmox-ve_9.2-1.iso.asc # off=0 ctb=89 tag=2 hlen=3 plen=563 :signature packet: algo 1, keyid A7BCD1420BFE778E version 4, created...

81.7% of data requests are for metadata. I assume ZFS can do with less memory to maintain a high hit rate? Pfsense workloads don't perform heavy write IO like databases/webservers etc.. Below numbers are for a full host. We will not add...

UdoB reacted to Johannes S's post in the thread Proxmox VE 7 is vulnerable to some type of 0day/RCE non auth with Like.
Thanks for the writeup. One thing I'm missing: Did you you recreate the cluster with a non-EOL version (PVE9) or did you resetup them up with an EOL version? If you did the latter I would reconsider since although you might have closed this...

UdoB reacted to netfront's post in the thread Proxmox VE 7 is vulnerable to some type of 0day/RCE non auth with Like.
We were compromised through CVE-2023-54391 on 1–2 September and rebuilt 22 nodes from backup. A few of the post-exploitation findings cost us real time, so probably worth sharing here. Getting the obvious out of the way first: we were on 7.4...

UdoB reacted to Johannes S's post in the thread Proxmox in enterprice environments with shared fc storage with Like.
Or to be more blunt: Just because somebody want everything to work like vmware that doesn't mean that it makes sense. ProxmoxVE and the underlying technologies are after all a different system with it's own tradeoffs, pros and cons.

UdoB replied to the thread Looking for best setup for rack server.Well, "a m.2" means a single one? That's a bad idea ;-) If you can install two (or more) of them the following sentence would be completely different: While it is still best practice to separate "the OS" from "the data" it is absolutely not a...

UdoB reacted to internetnoob26's post in the thread [SOLVED] Proxmox VE 9 on Toshiba Haswell laptop: ~20 W → 4–5 W idle [Report] with Like.
11. RAPL showed the CPU was already extremely efficient At around 9 W wall power I also measured Intel RAPL energy. Over roughly 30 seconds I obtained approximately: CPU Package : 1.89 W CPU Core : 0.085 W DRAM : 1.47 W This was...

UdoB replied to the thread Lower ZFS ARC max size.Well, it already is lowered. The "classic" limit was 50 % of the system Ram for many years; the compile time limit is 90 %, afaik ;-) @xybo gave the correct hint: check the actual hitrate while running your specific workload.
-
I agree that the 2 GiB + 1 GiB/TiB rule of thumb is probably too simplistic for this use case. ARC size should be based more on the actual workload and memory pressure than on the total ZFS pool size. For example, I have a ZFS storage with...

UdoB replied to the thread On package updates, how do you know when a reboot is required?.First I must admit that I really didn't know which script is responsible. It just didn't matter to me - as it just did work. Always. And now I had to check :-) This one is it (probably): ~# grep -R reboot-required /etc/kernel/ /lib/kernel/...

UdoB reacted to leesteken's post in the thread Intermittent multi-second ZFS I/O latency on 4x Crucial BX500 RAIDZ1 – SMART clean, latency changes between drives with Like.
BX500 has QLC and it need to flush it's SLC cache to it. And it cannot cache sync writes. Also, RAIDz1 has low IOPS compared to a ZFS mirror and is not good for VM/CTs. QLC and RAIDz1 and BX500 have been discussed on this forum so many times that...
