UdoB replied to the thread Installation cannot find hard drive.Note: I do not know that card. First guess: check in the BIOS if it is set to fake raid. Switch all drives to AHCI if it is. If it is a "real" Raid controller switch it to HBA mode. -
UdoB reacted to HappyHog's post in the thread Proxmox File Level Restore Portal (Open Source) with snapshot timeline and guest restore with
Like.
Proxmox's file-restore feature (browse/download individual files out of a PBS backup via the helper-VM) already does the hard part — it's just missing a way to scrub across snapshots instead of picking one at a time from a flat dropdown. I built... -
UdoB replied to the thread Wünschenswert: Anzeige der NIC-Geschwindigkeit.Nein. Ein automatisches downgrade geschieht nicht. (Ein downgrade klappt nur manuell per CLI.) "apt full-upgrade" macht (ohne manuelle Intervention) immer nur upgrades von älteren auf neuere Pakete. In der Realität kommen die Pakete aus non-sub...

UdoB reacted to leesteken's post in the thread [SOLVED] Windows VM with a passed through GPU slows down whole host to near not responding when powered on with Like.
Your CPU only has 6 cores with 2 threads each and you are giving at least one VM 12 VCPUs while Proxmox (and other VMs) also needs to do stuff like graphs and emulating the e1000. Try giving your VMs no more than 4 cores (each) and Proxmox will...

UdoB reacted to gfngfn256's post in the thread Proxmox VE 7 is vulnerable to some type of 0day/RCE non auth with Like.
I think any Cloud hosting service / provider, offering a Proxmox VE instance setup, should offer a full suite of available & appropriate initial options covering storage, networking, firewalling & exposure in their setup. I do not consider a...

UdoB reacted to chrcoluk's post in the thread Proxmox with ZFS + SSDs: Built-in TRIM cron job vs zfs autotrim? with Like.
I suspect debian developers have overreacted to some edge cases, if there was en mass buggy behaviour with consumer SATA SSD's, Then Microsoft the owner of the biggest OS on the planet would be disabling Trim, instead its enabled per transaction...

UdoB reacted to proxuser77's post in the thread Proxmox VE 7 is vulnerable to some type of 0day/RCE non auth with Like.
PVE 7 is the second-to-last version. We’re now on version 9, and I think version 8 is also nearing end of life, or has it already reached it? I’m not 100% sure. Either way, the longer you wait, the more complicated and time-consuming it’ll be to...

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.
Another option would be to run a PVE7 VM inside your PVE9 host. Obviovusly this would be a bad idea for VMs performancewise. For VMs it's best to migrate them to your new host and be done with it. But if you happen to have some old containers...

UdoB reacted to SteveITS's post in the thread [SOLVED] Issues with New Install, loosing access to VMs with Like.
My first thought is you’re overcomplicating Ceph. Why not one pool with lots of drives for resilience and more distributed I/O? What does the top of the Ceph status page show when one host is off? Should not be worse than yellow.

UdoB reacted to fabian's post in the thread Feature idea: saferemove mode to skip forced zero-write (blkdiscard --zeroout) on storage that guarantees zero-after-discard (e.g. NVMe DLFEAT) with Like.
but please note - we've had plenty of reports about storage appliances stating that they zero on unmap/discard, but empirical evidence shows they actually don't. or only do half of the time, if some block size and alignment assumptions are met...

UdoB reacted to proxuser77's post in the thread Storage setup? Separate OS and data drive? ZFS + Slog? with Like.
The top commenters here are all professionals who plan and manage Proxmox deployments for SMBs or even large enterprises. In a homelab, I’d simply leave out the SLOG, live with whatever performance the existing SSDs provide, and make regular...

UdoB reacted to sirbryan's post in the thread Proxmox Virtual Environment now available for 64-bit ARM (arm64)! with Like.
I spent this summer building a custom kernel for the MikroTik CCR2116 router and the RDS2216 server. Both use the Annapurna Labs Alpine AL73400, which is a 16-core 2GHz ARMV8-A processor (used in Amazon Graviton 1), with 16 or 32GB of RAM. I...

UdoB replied to the thread Storage setup? Separate OS and data drive? ZFS + Slog?.Okay. In this case you obviously know how to calculate risks and handle problems. Congratulation. Really. Actually I don't have much experience with a SLOG - I just don't have the use case to write so much data in SYNC mode that an SLOG would...

UdoB reacted to leesteken's post in the thread Storage setup? Separate OS and data drive? ZFS + Slog? with Like.
ZVOLs also use CoW (like everything else on ZFS, which also makes it relatively slow) and new metadata especially never overwrites old metadata. It's always written separately and only when it's actually on the drive (synchronously) then the old...

UdoB reacted to leesteken's post in the thread Storage setup? Separate OS and data drive? ZFS + Slog? with Like.
Good to hear, thanks for explaining this. 16G is good enough for a Proxmox installation or an SLOG or swap (since Proxmox does not support memory over-commit). Although people are not overly enthusiastic about adding an SLOG for getting better...

UdoB reacted to leesteken's post in the thread Storage setup? Separate OS and data drive? ZFS + Slog? with Like.
The 16GB Optane might be useful as a SLOG or a special device (but the redundancy must at least match the data redundancy). I fear that the 58GB and especially the 375GB might be hybrid drives with 2 PCIe lanes connected to a small Optane and...

UdoB replied to the thread Storage setup? Separate OS and data drive? ZFS + Slog?.That's easy: get two "Enterprise class" NVMe with PLP. (But prepare for a heart attack while looking up prices.) Then run everything on this single mirrored vdev - on ZFS of course. You asked for "best performance" - and personally I do always...
