Aalexskysilk replied to the thread Proxmox VE 7 is vulnerable to some type of 0day/RCE non auth.Yes, but also no. Expecting and depending on your software to be faultproof is a fools errand. Yes, you should close doors you are aware that are open but that doesnt absolve you from all the doors you are NOT aware of. The "crime" here wasnt...

Aalexskysilk replied to the thread Need advice: MIDI Software on Proxmox - Kernel Recompilation versus VM Passthrough?.Why? lxcs are not dependent on any logical handoffs. if the device is accessible to the host, its accessible to the container. You wouldnt be passing the device, you'd give permission for the container to access its driver. the bus location is...

ADo you use Veeam for backups? You could also use this new community-made tool, if you have a lot of VMs to migrate: https://github.com/VeeamHub/moov

Aalexskysilk replied to the thread Can a Proxmox VM Feel Like Bare Metal? Dual 144Hz + GPU Passthrough + Low Latency.Thats an unreasonable metric. "maximum" means nothing here. All you can do is use best practices for your guest OS. whether that yields acceptable results is up to the operator to determine- slow storage will impact your experience way more then...

Aalexskysilk reacted to bbgeek17's post in the thread Quick HOWTO on setting up iSCSI Multipath with
Like.
Microsoft is still catching up with NVMe/TCP, and we've encountered PSODs on ESXi in the past related to NVMe/TCP connections. iSCSI is extremely mature and broadly supported. As mentioned, it may make sense in more scenarios than initially... -
Aalexskysilk replied to the thread Quick HOWTO on setting up iSCSI Multipath.iSCSI isnt deprecated or dead, which is to say the driver stack is included with every modern operating system. having said that, iscsi makes little sense in a world where nvof exists.

Aalexskysilk replied to the thread Can a Proxmox VM Feel Like Bare Metal? Dual 144Hz + GPU Passthrough + Low Latency.The point- you dont NEED pve to achieve your desired functionality, and USING pve for it involves uncomfortable compromises with user experience. But you do you :) If it were me, and you havent yet purchased anything- I'd buy two machines- one...

Aalexskysilk replied to the thread Has anyone tried Ubiquiti's ENAS for ProxMox's storage array?.the BRAND doesnt exist. The product line successors certainly do, and they were ALWAYS expensive in relations to the cost of "raw disk." If your RTO policies allow for a spof in your storage, I'm sure the ubiquiti nas will work. Having said that...
-
Aalexskysilk replied to the thread Can a Proxmox VM Feel Like Bare Metal? Dual 144Hz + GPU Passthrough + Low Latency.crazy idea- given your use case, why not start with a normal Windows/Linux desktop and run the rest of the vms in qemu? PVE isnt even desirable in your use case...

Aalexskysilk replied to the thread ZFS on SAN LUN(s).I think we're using support in different ways. the software stack you describe can run on those (or any other) linux. whether you want to depend on the solution and have someone who can assert its uptime, thats what I mean. see...
-
Aalexskysilk replied to the thread ZFS on SAN LUN(s).this is true, but have you ever implemented it? its slow as molasses. mdadm parity raid... brrr. THAT is brave. also, there is no "self healing" of any kind. This has the same problems as a HA zfs filer. the only "upside" is that you dont have...
-
Aalexskysilk replied to the thread ZFS on SAN LUN(s).Not uncommon, but fraught. I've seen effort to make a HA ZFS filer solution for AT LEAST 20 years. There are 3 commercial solutions I'm aware of (Truenas/Nexenta/Intelliflash) but all three have either migrated/migrating to a different method of...
-
Aalexskysilk replied to the thread ZFS on SAN LUN(s).in before @UdoB ;) thats a bad idea. you can make it work but it would be brittle, unsupported and unsupportable.
-
Aalexskysilk replied to the thread freezing Linux VMs and sporadically connection issues regarding a node.So not a network problem. next step is to perform an strace on the qemu process and see whats locking up.
-
Aalexskysilk replied to the thread ZFS on SAN LUN(s).Running ZFS on a obfuscated device (eg, RAID LUN) isnt dangerous per se; its no safer then any other filesystem on raid- which is to say you have no checksum correction facility at the filesystem level so you're paying the zfs tax for no gain...
-
Aalexskysilk replied to the thread ZFS dedup on a Proxmox host in 2026 — has fast dedup changed the recommendation?.If the discussion is strictly on a "worth it" basis, its worth noting by what metric. Ram costs more then storage. Fast dedup is less hungry but thats still ~2G per deduplicated TB- although you could substitute a special device for SOME ram usage.
-
Aalexskysilk replied to the thread Snapshot best practices.ceph and zfs are CoW native; snapshots are not "real" in the sense that the data isnt separated- think of snapshots as bookmarks. VMDK isnt, and so snapshots are addon files. qcow2 can exhibit similar performance degradation. In summary-...
-
Aalexskysilk replied to the thread freezing Linux VMs and sporadically connection issues regarding a node.when you say the VM freezes, do you mean it isnt responding to network traffic or local (console) access? if its console access, is it a specific VM or all VMs on the nodes? If its network access, check your raw interfaces for faults. ifconfig...

ASomeone has to maintain it, which means proper testing and release management. If the goal is Microsoft certification/WHQL, that also means establishing the appropriate relationship with Microsoft, going through their certification process, and...

Aalexskysilk replied to the thread Advise: shared vm storage using nfs.NFS doesnt care; certain write patterns can benefit. a slog is useful when the following two things are true: - The write pattern is large number of synchronous small IO (eg, backing a database) - The backing store is an order of magnitude...
