Upgrade Existing System
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello. Has anyone had any experience performing an "upgrade of an existing system" with SuSE 9.1 Pro, rather than performing a new install? I am upgrading from v8.0 to v9.1 and was wondering if this method is safe. Thanks.

It's safe enough, but do expect to spend some time sorting out a few problems. They'll generaly be minor things, but there *will* be some issues. :) Scan over the rpmnew and rpmsave files that show up in /etc. The diff utility is your friend, here. Figuring out what changed will take a few minutes, and then you should be back up with no (undocumented) problems. Don't do what I did - I added the 9.1 install directory to my install sources in YaST (in addition to the 9.0 and 8.2 sources), then ran the "update existing system" thing while logged in, under X on my 9.0 system. The results were not at all good. :) Regular updates are fine, though. Just don't update a running system while it's running, even though it'll let you do so... --Danny
Has anyone had experience running SuSE on a Dell PowerEdge 1750. Or a dual Xeon with hyperthreading. We have installed Suse SLE 9.0 with no problem but are seeing poor performance. I/O operations are much faster than our legacy hardware (PowerEdge 500) but processor intensive operations (ie garbage collection and searching documents) perform much worse. I know that these are vague criteria, but I'm just trying to get a handle on general configuration issues with dual processor / hyperthreaded machines and the latest Suse distros with kernel 2.6. For example: the install set my grub arguments to have acpi=off. Some of my reading suggests that I may want to change this to: acpi=ht What are the ramifications of doing this? It turns on hyperthreading, but do I need to do anything to my kernel before doing so? The application in question is a Java web application running on Tomcat. Any insight would be much appreciated.

I've started rebooting anytime I do an upgrade. It seems to help, but I can't prove it. Rich -- C. Richard Matson

I was unsuccessful with this, but I backed up, so it was no big deal. I have heard others have had success. IMHO doing this without backup is suicide. -- Tony Alfrey tonyalfrey@earthlink.net "I'd Rather Be Sailing"

It should be added that going from 8.0 to 9.1 is a *major* jump. Two releases in between. The greater the jump, the better the odds for a problem in my opinion. -- +----------------------------------------------------------------------------+ + Bruce S.

As safe as upgrades are :-) I have always upgraded. Usually it works, sometimes it doesn't. Therefore, I make a point of having a full backup previous to starting the upgrade: if all goes well, I just have a good backup, which always is a 'good thing to have'. If it bombs out, then I can start afresh, without loosing a single file. Problems you may have? If you have several partitions, some of them might not be detected (it happens to me); but they can be manually mounted. Also, having as much free space on the '/' partition comes handy. You will have to decide about a lot of packages that have disappeared or have new names or are incompatible. And after the upgrade, you will have to review many configuration files, but the system will tell you about them. -- Cheers, Carlos Robinson

Jesse It really depends on what hardware you're using and who you ask. I just did it to an HP laptop and it went very well. No problems at all but I did have to use sax2 to get the trackpad tapping to work.
The best way to trick your machine into doing an easy upgrade is to backup at least the /home directory before you start the upgrade. ra
I just did it last night. Dell 5100 Laptop with 9.0 pro to 9.1 pro I also tried the update from yast to start. It wasn't pretty. Not fatal just a pain. To add to my merriment I had quite a few customized packages installed and the supplemental KDE 3.2 packages. It did upgrade, it took me a long time to get it straightened out (my fault for being too tricky) and I lost no data. I do have one minor, nagging bug left. The KDE run command (alt-f2) keeps telling it can't run /opt/gnome/bin/mozilla when I enter mozilla in the box... Duh! Mozilla moved. This only happens with a pre-upgrade account. Accounts created after the upgrade work fine. I guess I could blow .kde away and let the system fix it, but that strikes me as somehow inelegant. Thoughts anyone? Jesse L. Purdom wrote:

Poor form to reply to ones own posting, but in this case I hope forgivable. I just finished upgrading another laptop from 9.0 to 9.1 This one went beautifully. Everything migrated perfectly, no errors a simply perfect upgrade. An absolutely fresh install with a backup is a way to do it too... I guess. In my life, it's also a luxury. In a perfect world, I wouldn't need and upgrade. Someone tell me please where I can requisition a perfect world. After this last week I want one *really* bad :) P.S. The ultimate cause of the problem with the Dell upgrade was disk labels. The Suse upgrade process didn't want to upgrade an installed system using disk labels vs device names in /etc/fstab.
