3 days? you sure got a lot of time to spare. If you backup everything and clean install… i think you can be done in less than 3 days and without much headaches.

Re the instructions, a reboot is needed after installing the new kernel. Next, most items, notably initscripts.rpm, won’t install as long as the old kernels exist on the server, so the old kernels have to be deleted along with items like kernel-utils, kernel-smp and so on.

Next, yum upgrade gave dozens of dependency errors. The way around that was to do a yum upgrade sane* first because it had the smallest number of errors (3 or 4). So I deleted the packages it choked on with rpm -e –nodeps and reinstalled the deleted packages via yum install one by one.

I lost my GUI drivers for some reason till I yum installed xorg-x11-drivers. Wonder why this was skipped.

After two days of effort, all 3 servers are back up. Only one of them I had to force install most things becuase of a wierd problem.

All 3 servers being identically configured had 5 kernels to begin with. On two after reboot, I removed all the pre Centos5 ones and 3/4 hours later had upgraded everything.

On the 3rd server, yum still gives me dependency errors for a number of rpm’s saying I have the older 4 kernels, but yum list and rpm -qa don’t show them.

Ideas?

Hope I haven’t screwed up my servers.

Thanks for instructions!

When doing the upgrade of the kernel rpm’s, after the “Clean up some old stuff”, I had to link some libraries to make wget happy:

ln -s /lib/libssl.so.0.9.8b /lib/libssl.so.4
ln -s /lib/libcrypto.so.0.9.8b /lib/libcrypto.so.4

There was also a typo in the wget for the kernel headers. The following URL works:
wget https://centos.sd2.mirrors.redwire.net/5.0/os/i386/CentOS/kernel-headers-2.6.18-8.el5.i386.rpm

Thanks.

I will post this also on my blog.
