Re: FS S5850 - 7 nodes lots and continuous "slow OSD heartbeats"

[Steven Vacaroaia <stef97@xxxxxxxxx>]

Hi Istvan,

Thanks for the suggestion

I am running Ubuntu 22.04 and the mlx5_core version is 5.15.0-135-generic with firmware 22.43.1014

What do you have ?

Steven

Hi,

Try to use the driver of the network card if you are on ubuntu even if you need to build by yourself, for us it fixed.

Hi,

We are in the process of using for production a 7 host reef ( 18.2.2) cluster 

and we noticed lots and continuous "slow OSD heartbeats"

although there is no clients, no data and the nodes are using 2 x 25GB for Frontend and 2 x 100GB for backend

The logical culprits is the network 

we have 2 x S5850 with  MLAG and LACP

I was wondering if any of you are familiar with FS and can provide some guidance as to how to properly configured ( or troubleshoot)

Note

We are  running in a air gapped environment so cannot provide outputs/config 

but here are some pictures 

Many thanks

Steven
