PHi everyone. Since it's pretty much impossible to buy workstation or server-grade hardware with 128GB or more right now, unless you've won the lottery, I got my hands on two 1L PCs with 64GB each, which I plan to use to supplement my existing...

Like.
Adding the mitigations=off parameter to /etc/default/grub yielded noticeable optimization and significant improvement. Performance in version 9.1 is particularly better compared to 8.4, so the hosts have been upgraded from 8.4 to 9.1.Below is the... -
JJohannes S replied to the thread [TUTORIAL] Tutorial: Unprivileged LXCs - Mount CIFS shares.It works the same way for NFS. You will need to adjust your uids though like explained in the wiki page referenced on the first page of this thread: https://pve.proxmox.com/wiki/Unprivileged_LXC_containers There are also a lot of discussions in...

Ddavis.klavins replied to the thread ACME Order "Failed - server reply does not look like a PEM encoded certificate".From what I can see version 9 correctly handles ACME certificates for us now. I don't think anything changed on the issuer part (though I'm not the one managing it). I think even the latest version of 8.4 handled it on one of the clusters I...

LnxBil replied to the thread [SOLVED] What are the best practices for using Windows as a Q-Device arbiter in a two-node PVE cluster?.Monitoring should be automatically done in the background from another system so that you have proper monitoring and alerting. This can be automated via pvecm if you want to do this, but don't manually look for stuff. That should work, too. You... -
JJohannes S reacted to Michiel_1afa's post in the thread [SOLVED] Does Proxmox VE support host–guest time synchronization similar to VMware? with Like.
Not sure if it is 'The' recommended way, but as I mentioned, we rely on a NTP source in our network so it is reachable for all machines. In your case if you do not have the means to set up a dedicated NTP source, using one of the PVE hosts, or...

JJohannes S reacted to Michiel_1afa's post in the thread [SOLVED] Does Proxmox VE support host–guest time synchronization similar to VMware? with Like.
This is not an 'ntp' option, this is for the startup of the vm, windows likes to have the system date/time in the local time zone, while *nix OS likes to have the system date/time in UTC. This option translates the host time for the vms to the...

JJohannes S reacted to uzumo's post in the thread [SOLVED] Does Proxmox VE support host–guest time synchronization similar to VMware? with Like.
When synchronized with NTP, the RTC is typically not referenced. For example, in Windows, it is referenced at startup. Once synchronization with NTP begins, the RTC is never referenced again. If synchronization with NTP has not started, it...

RI tried this years ago and was sadly not able to do it properly and beeing rock solid at the same time so we just bought two disks / BOSS-card-equivalent per host and went with it. Never had any issue since then and never looked back.

Jjo_strasser replied to the thread Debian 13 LXC await network timeout.The workaround "systemctl disable ifupdown-wait-online.service" is working only on older systems (pre-debian-13.1.2). I can see that since 13.1.2 "ifupdown" and "ifupdown2" is installed, on older systems only "ifupdown". The issue is triggered...

Rrds76 replied to the thread e1000e eno1: Detected Hardware Unit Hang:.I could confirm, turning TSO off on phy nic (post-up script) fixed this issues for me as well (I219V), no hangs so far (2w), only slightly higher cpu utilization 1-2% during nic traffic

GHello. Could we say 'completed' or 'finished' instead of stopped for a successfully completed job? Successfully stopped is a bit weird. I thought someone stopped this job.

Ssgw replied to the thread OCFS2(unsupported): Frage zu Belegung.Der Scrub dauert schon wieder seit gestern an. Die Belegung steigt langsam, unangenehm.

Ppulipulichen replied to the thread [SOLVED] Does Proxmox VE support host–guest time synchronization similar to VMware?.Thank you for the detailed explanation. It really cleared up my long-standing confusion. I previously thought checking "Use local time for RTC" was enough, but now I understand it only affects the initial boot and that a continuous sync mechanism...
