10th NVMe drive not showing up in O/S installation

Bashed · 08-16-2023, 07:32 AM

Trying to install AlmaLinux 8 on a Dell R640 equipped with 10 x 7.68TB NVMe U.2 drives. All 10 show up in iDrac storage inventory so they're recognized, but only 9 show up in AlmaLinux install (via IPMI). I have replicated this issue with AlmaLinux 9, Ubuntu 20, Centos 8 Stream as well. I have power cycled a few times also. Something is off.

Curious why and if there's a fix?

It may be kernel limitation (but I doubt it), or it may be udev limitation. If I was you I'd check udev rules first.

Thanks but where are "udev" rules found? Not familiar. I replicated this problem on multiple Linux o/s, so it's not a software issue I assume

Would appreciate some help on this, thank you.

Hi,

As root you can use from command line in a terminal; 'ls /etc/udev'.

Hope this helps.

Why don't you create missing device node(s) by hand to see if this works. If kernel nvme driver cannot handle the tenth device then it won't work.
