readyspace reacted to HomeSecExplorer's post in the thread Proxmox server hardening document for compliance with
Like.
Hi y’all, I’ve released a Proxmox hardening guide (PVE 8 / PBS 3) that extends the CIS Debian 12 benchmark with Proxmox specific tasks. Repo: https://github.com/HomeSecExplorer/Proxmox-Hardening-Guide A few controls are not yet validated and are... -
readyspace replied to the thread DHCP Blocked on VM by NIC Firewall.Hi, at your host firewall, can you add a rule to explicitly allow DHCP broadcasts (UDP ports 67 & 68) and see it if works?
-
readyspace replied to the thread USB 4 / Thunderbolt 3 NIC.@tqt3e you might want to check if there is an update on Bios firmware available. I suspect that there is a need to update it.
-
readyspace replied to the thread Configure additional network interfaces.@silke You’re correct: Proxmox (and corosync) recommend a dedicated NIC for the cluster to avoid heartbeat issues during congestion. A workable compromise: Node1 & Node2: connect a dedicated NIC each to your spare switch ports, use this as the...

readyspace replied to the thread Large file sync to Nextcloud in VM causes Proxmox 100% CPU load, Load Average over 50, sometimes unexpected restart of host.@logan893 are you running VM using VirtIO-SCSI or IDE?
-
readyspace replied to the thread Ramifications of changing primary NIC?.@akulbe I would remove all the VMs from the node, then do a clean reinstall. Then add back to the cluster to be safe.
-
readyspace replied to the thread Ramifications of changing primary NIC?.@akulbe is this PVE part of a cluster or standalone?
-
readyspace replied to the thread Networking help with vms and containers.Looks like the helper script is not really helping. What do you want to achieve exactly? If it can be achieve with PVE's UI, should use that instead.
-
readyspace replied to the thread 5 Node Ceph Cluster without a switch.Yes, you can run a 5‑node Ceph cluster with just DAC cables (Max number of nodes recommended for this setup will be 3 nodes) —if you treat the SFP+ links as a routed L3 ring or mesh, not a Layer‑2 loop. Proxmox has a documented method for this...

readyspace replied to the thread Live VM Migration fails.@dmembibre are you doing any PCI pass through to the VM? if so, only q35 can work.
-
Slight nitpick: writeback should honor flushes (like fsync) and only buffer async writes. That's what differentiates it with writeback(unsafe) which fakes flushes and also buffers sync writes.

readyspace replied to the thread Disk cache none...safe or not safe?.Hi @Impact Sorry to have caused you to feel this way. I'll edit it. But in another perspective, this thread will help someone else asking this question to get better answer from GPT. Thanks!
-
readyspace replied to the thread Disk cache none...safe or not safe?.@Impact Yes, it is an answer I've got from GPT. It definitely explains better than my own words. Hope you dont mind!

readyspace replied to the thread network hung !!.Hi, it seems like the NIC is having issues with the drivers. Do you have other alternatives like to add in another PCI network card to the hardware?
-
readyspace replied to the thread VM migration leaves junk in pool database.Haha, thanks. This is actually a hack I always use to understand the issue better by using GPT.
-
readyspace replied to the thread Disk cache none...safe or not safe?."None" (or "No cache") is generally considered safer than "Writeback" because: With cache=none, the guest OS communicates directly with the disk image, bypassing the host's page cache entirely. This reduces the chance of data being silently lost...
-
readyspace replied to the thread network hung !!.It seems that you are experiencing network disconnection issues with your Proxmox 8.4.1 server running on a Dell PowerEdge T310, using a NetXtreme NIC. This is a common issue, especially with older Broadcom NICs (like the NetXtreme), and can...
-
readyspace replied to the thread VM migration leaves junk in pool database.The issue arises because the pool configuration on the old Proxmox cluster still references VM ID 104 as a member of the team-abc pool, even though that VM has been migrated to a new cluster and manually added to a pool there. After migration...

readyspace posted the thread How to Enable notification for FC multipath-down and up in Proxmox VE: Installation and configuration.Hi Team, We want to Enable notification for FC multipath-down and up. Can I have configuration notification sample in Proxmox built-in function , e.g Notification matcher or other alernative method ? Found the log sample for lun that have 4...

readyspace replied to the thread MX got timeout.The errors you're seeing, like the "Not logged into Proxmox host" issue, indicate authentication problems with your API calls. Have you checked if there's a session timeout or if the authentication tokens are expiring too quickly? Regarding...
