Thank you so much. Worked like a charm. Separate switch for the ceph cluster network is definitely the way to go. Combining the proxmox and ceph public networks means I can keep everything on 10gbe. Perfect.

Background: 4 nodes 3 nodes have 2x10gbe and 2x1gbe 1 node has 1x10gbe and 2x1gbe 1 x unfi 16xg NEW 1x mikrotik 4 port 10gbe switch I had everything setup and working: 10.0.90.0/28 Proxmox corosync on 1gbe interfaces 10.095.0/28 Ceph cluster AND public network on 10gbe interfaces 10.0.50.0/24...

Right now I have a three node cluster. Two of the nodes have ECC memory and the other one is a NUC. Is there any way to preference writes such that all incoming data hits one of the 2 ECC nodes before being replicated to the NUC node? I’ve used primary-affinity on the OSDs attached to the NUC...

Sorted. Didn’t actually have to install the driver - it’s already part of the kernel. All I needed to do was authorise the thunderbolt device and it shows up. If anyone needs the instructions I will post them here.

Hi, I have a NUC with a thunderbolt 3 port to which I have connected a QNA-T310G1S. Its not showing up in lspci. 00:00.0 Host bridge: Intel Corporation Xeon E3-1200 v6/7th Gen Core Processor Host Bridge/DRAM Registers (rev 03) 00:02.0 VGA compatible controller: Intel Corporation Iris Plus...

Thanks for the reply though

What about separating Corosync network and Ceph osd network for rebalancing? How can I share the Ceph public network and Proxmox public network?

Hi, I’m in the planning stages of setting up a three node cluster. 2 of the nodes will have dual 10gbe and dual 1gbe NICs, and the other has a single 10gbe Nic and a dual 1gbe Nic. Reading through the documentation and doing searches it seems that Proxmox wants 2 NICs - 1 for Corosync and one...

Alternatively, I could just leave the one drive in the nuc connected to SATA. But that would leave an asymmetric OSD setup with 2 nodes having 3-4OSDs per node and the nuc only having a single OSD. I think I’ll just have to bite the bullet. Trial it all and see if it bites me in the b**t.

Yeah, The USB-C enclosure isn’t an elegant solution, but a stop gap until I can get another node up. It’s a 4 disk enclosure that appears as single disks. Bandwidth is limited to 5gbps but I’m only running 3 3tb disks. I’m not expecting performance, but do want reliability. I’ve already got a...

So I’m trying to cobble together a homelab cluster. Its a mixed bag with an e3-1230v3 16gb ECC node, an intel nuc 32gb non-ecc (USB 3 hdd external enclosure) and soon an AMD 3700x with 32gb ECC ram. How does Ceph play with such an asymmetric setup? Each node will have 3x3TB hdd and 10gbe (the...
