That did the trick ! Thanks a lot

waow thanks it is worth a try

BCM57502

>= 15 Gbps in both directions

I'm suspecting a host issue... Using nftables instead of iptables could impact performance ?

Hi, Weird behavior for a Ubuntu Server 24.04 VM. Download speed ~500 kbps While a debian 12 VM is able to download at full speed 1000 Mbps. On PVE host no bandwidth issue, firewall on (nftables), masquarade, ipv4 forwarding activated. VMs use CPU type = host with numa activated as well...

Thanks! I don't think that network downtime is > 1 or 2sec with default parameters. The main question is how ceph handles such network outages. I guess it is OK for corosync and VMs as well. But when this happens, the entire Ceph cluster is down twice for 2 seconds. Moreover, mikrotik stable...

Thanks I also worked with FS, Dell OS10 S5248F-ON which seems to be similar to SN2410 you 're using ... Don't recall a preemption behavior on each reboot with them...

Hi, I plan to build a new proxmox ceph cluster (3 nodes). LACP 2x25 Gbps for ceph LACP 2x10 Gbps for VMs My question is related to the switches, I want mlag switches indeed. Mikrotik was my first choice due to functionalities and low budget as well. I have 2 CRS310 and have settled a very...

Hi, Can confirm the issue for 50% of my PBSs

Thanks, I'd prefer new devices :) my servers have mostly 2+ SFP28 ports so I assume I will go for a device that have at least sfp28 or 100 Gb with breakout cables

Hi, I usually buy FS modules and these modules work as expected despite low costs. I'm wondering if you guys also use FS switches, 25Gb+ models with mlag. Well known network brands are very (to much) expensive these days ! Pro/cons appreciated ! Thanks !

A good option too could be to create one 4x25 Gb LACP (via 100Gb NIC and breakout cable or 25Gb cards) and work with VLANs....

Thanks, I don't need 2x25 Gb to connect VMs indeed. But with 2x(2 x 25Gb) cards . there is 2x25 left for vms.... My switches can handle MTU 9000/Hash layer3+4 as well

Hi! Wow 12 NVMe per node, no I plan to begin with 4 NVMe (1.6TB) per node. 100 GB breakout cable could be a way for future needs thanks ;) How do you use each interface on your interfaces config file ? Pluging the breakout cable make them appear ?
