Upgrade from RHEL 4.6 to 5.1 errors

noir911 · 05-25-2009, 08:35 PM

I have upgraded Red Hat Enterprise Linux AS release 4 (Nahant Update
6) to Red Hat Enterprise Linux Server release 5.1 (Tikanga) - the
system starts without any problem but while booting up I get "errors":
from udevd (I couldn't capture all the errors
& they don't seem to be in any log file). But they look something like this: "udevd: add_to_rules: invalid kernel operations"

udevd seems to be running (/sbin/udevd -d).

There is no SELinux (it's disabled), no iptables (it's stopped/ disabled)

Thanks.

How did you do the upgrade? Generally(on RH based distros) it is strongly advised to do a clean install when jumping major revisions (4.X to 5.X).

Why go with 5.1? 5.3 is current.

Support of this nature is covered by you subscription, what did RH say?

I've never heard of any one trying this before. A clean install from 4.x to 5 has to the the way to go, as there are so many differences between them. I would also be interested to find out what RH say?

More generally, Red Hat does not support in-place upgrades between any major versions of Red Hat Enterprise Linux. (A major version is denoted by a whole number version change. For example, Red Hat Enteprise Linux 4 and Red Hat Enterprise Linux 5 are both major versions of Red Hat Enterprise Linux.)

I guess backup those configuration files/data etc and rebuild the box from fresh.
