Hi Spirit,
It'll be a little while before the team can revisit this (and I'm currently OoO). That said, increasing the default cache size likely introduces serious real-world risks. I believe it creates a denial-of-service vulnerability and...
Hello Everyone,
Here is a brief update from our team regarding this advisory. The recently reported issues with NVMe/TCP native multipathing have now been addressed. The relevant fixes are included upstream and are part of the Ubuntu kernel...
First, I would normally expect two paths per lun. You are showing 2 individual LUNs that the OS only sees once. So while its ok to have Multipath sitting there, I do not think you actually have multipath.
You already posted "multipath -ll" and it...
@fba is correct. For several OS generations now, official cloud images have disabled password authentication by default. SSH key authentication is the standard. Beyond that, custom cloud-init is extremely powerful and can be used to customize...
the originally attached VM config:
scsi0: local-lvm2:vm-121-disk-1,size=1T
The VM configuration you attached contains only one virtual disk/image - "scsi0". It is located on storage called "local-lvm2". You subsequently provided your storage...

When a snapshot is deleted, the system merges data from the previous QCOW image and LVM logical volume into the new QCOW image and logical volume. This merge process allocates additional storage in the new logical volume but does not...
Hi,
thanks for the article, I hope you enjoy my work ^_^
about performance, they are still performance improvement possible, mostly with qemu l2 cache size. Currently it's really depend of the qcow2 volume size, it's working up to around...
Hi Spirit,
Thank you for your hard work! I especially appreciate how cleanly the feature is integrated, with no excess knobs or tunables. Great job by the whole team!
We're aligned on the QEMU caching. Larger caches can help somewhat, but it's...
I presume this isn’t a VM running on the same PVE host?
From what you’ve described, you have two storage pools: iSCSI and LVM-Thin. One depends on the other, but PVE currently has no built-in way to declare that dependency. This creates a very...
Hi @caslanx , please note you must use the multipath device (mpath) and never the underlying sdX device.
In your case it seems to be str01_pool_a_sssd.
But, the device already contains VMFS structure and you do need to wipe the "mpath" device if...
The allocation of disks (LVs) is not done manually, PVE does that automatically.
However, it will likely produce the same error if you were to try to create a 100G VM disk via PVE GUI. Since we have no information about your current...
There are few times when using an older or common architecture is needed:
- moving between Intel and AMD (never guaranteed to be seamless)
- moving VM from newer Hypervisor CPU to Older. Absence of some flags/commands can cause OS crash
- using...
Hi @caslanx , welcome to the forum.
This is the primary source of your issues. There is no such thing as iSCSI SAS cable. iSCSI is a storage protocol designed to run over TCP/IP. SAS is a point-to-point serial protocol for direct-attached...
Keep in mind that the banner that shows "connect to this IP" at the console does not always reliably update. You should login via the console and confirm the IP "ip a".
Sounds like you moved the PVE between different tenants, so your network...
Hi Everyone,
I'm excited to share a deep dive into one of the notable new feature in PVE9: the enhanced snapshot functionality designed for legacy SANs. This feature represents a meaningful step forward in expanding PVE's compatibility with...
Can you share your "/etc/pve/storage.cfg" ?
Also, what is serving your iSCSI?
Finally, what version of PVE are you running: pveversion -v

Hi @powersupport ,
Would you clarify your setup for me? You moved from local SSD to NFS hosted in a VM on ESX backed by spinning rust? At the very least, I’d suggest starting your fio testing inside the ESX VM.
Your VM configuration file shows a...
Hi @Amila, welcome to the forum.
To receive an official response from Proxmox GmbH, you should contact them directly via shop.proxmox.com.
That said, your proposed architecture looks fine. Proxmox GmbH will likely support it as far as PVE is...
It should start.
Likely will be ok, as much as it can be on 7yo pc
no, you should not run into issues. But if you were to use some other ARCH than host, you could. The 7yo PC will not support CPU commands introduced in younger generations.
Use...
Hi @daus2936 , yes, of course.
