 On Fedora 35, and I can reproduce your case,
# modprobe nbd nbds_max=3 && ls -l /dev/nbd* | wc -l
3
# modprobe -r nbd
# modprobe nbd nbds_max=42 && ls -l /dev/nbd* | wc -l
42

Hello.Recently I faced strange problem - when I load nbd module on my freshly installed fedora 35 x86-64 there are only 8 nbd devices nbd0 - nbd7, while modinfo shows nbds_max=16When I load nbd with nbds_max=32 - same thing, 8 nbd devices.
But loading nbd with nbds_max<= 7 works like expected.
Looks like there is a limit somewhere.
I looked in the udev rules, in logs, but so far found nothing of interest.
Do you have any idea what it can be and how investigate the issue?
