[lustre-discuss] Lustre 2.17 Client on Kernel 6.12.0-124.20.1.el10_1

[Aurelien Degremont]

Hi,

You should look at the system and especially kernel logs when this is happening, to understand what's going on.
Also, note that loading 'lnet' modules is not sufficient to configure Lustre network, either it will be autoconfigured when loading lustre, or you need some lnetctl command to do it, depending on how you configure it.
See https://doc.lustre.org/lustre_manual.xhtml#configuringlnet

Hi
Recently I installed Rocky Linux 10.1 (Red Quartz) and updated kernel package to (6.12.0-124.20.1.el10_1) as per Lustre 2.17 Client supported version and I'm using DOCA OFED (3.3.0-088000) driver for IB Interface of 400G.

Once everything is installed, as I execute  #modprobe -v lnet suddenly complete machine gone out of network and after a certain time-interval network get live, but still lnet not loaded to that I can mount lustrefs.

I tried to remove o2ib0 and try the same with tcp0, but the issue still remains the same. Kindly help to resolve this issue.
