we already have previous reports about HPE MSA (and Dell) appliances misbehaving in exactly this fashion - they advertise support for zeroing unmap, but only do it when the request matches some conditions, and simply ignore the zeroing part...
Hi @aday , welcome to the forum.
The journal line Cannot find device='z…' nor node-name='z…' on the target comes from the incoming dirty-bitmap migration: it couldn't find the block node the bitmap was attached to, so QEMU dropped the bitmap and...
I'd recommend trying to reproduce this directly on the PVE host, bypassing the VM. Allocate a raw volume with pvesm alloc and test against the block device directly (or mkfs and mount it).
My suspicion is that LVM doesn't clear extents on...
Hi @eatonjb, welcome to the forum.
The first thing I would check is the system log:journalctl. There may be some clues there.
If the customer has to manually power-cycle the server, that may indicate that there are messages on the console. If a...
Hi @mira,
I’ll check with the developers on the current status. They are currently working through a number of existing deliverables, so this is in the queue but is not something I expect to be completed immediately.
Since we have not seen this...
You could try virt-sparsify on your file to see if that helps.
Blockbridge : Ultra low latency all-NVME shared storage for Proxmox - https://www.blockbridge.com/proxmox
@bbgeek17 no disagreement. I was simply pointing out that the premise that a full node fence is required isnt necessarily true for the proposed solution to work. I'm not suggesting its easy, not fraught with gaping holes, probably too slow to be...
Sorry, I missed the forum name - that documentation/procedure is for the PVE Cluster.
If you have collection of single nodes under PDM, take a look at this thread:

Hi @bishoptf ,
Have you checked the cluster guide? https://pve.proxmox.com/pve-docs/chapter-pvecm.html#_remove_the_cluster_node
Blockbridge : Ultra low latency all-NVME shared storage for Proxmox - https://www.blockbridge.com/proxmox
Hi Mike,
It's a good idea, but it's worth noting that discard has a rough history. SATA TRIM often didn't guarantee zeros, a bunch of drives corrupted data on queued TRIM and are still on the kernel blacklist, and arrays have been all over the...
A new article for ARM system users covering performance troubleshooting
Blockbridge : Ultra low latency all-NVME shared storage for Proxmox - https://www.blockbridge.com/proxmox
Now that the system is "stable" after dealing with the black screen and the watchdog resets, we've started looking at performance. Our first look at storage performance was absolutely terrible. And after some head scratching, learning a bit more...
Hi @alexskysilk , you know I love a good bash loop, but ACL toggling is vendor-specific. It often only gates new logins, so an established session keeps writing until the target decides to drop it, and whether it does that on revoke is up to the...
Hi @300cpilot,
There is no official place to post third-party scripts. In this context, "official" generally implies that the material is endorsed or supported by someone in an authoritative capacity. Proxmox cannot reasonably endorse or support...
Ok @huganega , I think we've figured this out. It takes a combination of things to trigger:
- A link that's "fast" (i.e., 25GbE) relative to your CPU (Skylake or Cascade Lake)
- A backup load running at full queue depth
- An array that doesn't...
A few comments about your observations:
There is absolutely no "valid DNS name" requirement for a VM name in the PVE, cluster or solo.
This is Ansible creator's choice, not Proxmox's.
A clone creates an identical copy of a VM, resizing a disk...
You should by all means discuss any concerns you have with PVE directly, either with Proxmox or a reseller during the pre-sales process.
There is nothing inherently impossible about changing software architecture. Whether a particular change...
Hi @delltech1, welcome to the forum. I'm glad you found the post useful. Your continued promotion of your AI plugin here and elsewhere motivated me to share it, because what you're promoting corrupts data.
This is a clear example of how rapid...
