Description Simon Hargrave 2004-12-09 06:13:56 EST
Description of problem:

After updating RHEL3.0 kernel to kernel-smp-2.4.21-20.0.1.EL I get 
erroneous messages on bootup: -

modprobe: modprobe: Can't locate module block-major-43.

These messages appear during the LVM startup phase.

I don't believe them to actually cause an issue (major 43 is network 
block device I believe), and I can block the messages with "alias 
block-major-43 off" in modules.conf, however this is just masking the 

Version-Release number of selected component (if applicable):


How reproducible:

Happens every reboot.

Steps to Reproduce:
1. Reboot.
Actual results:

Error message on startup.

Expected results:

No error message.

There's 3 options to deal with this:

o install kernel-unsupprted which contains nbd
o stay with the workaround you have
o ignore the message
