Cross-grading from i686 to x86_64: it is possible (but unsupported)
Hi, after reading a lot of advice about not doing it, and only a couple of reports from guys who did it, I finally decided to try to cross-grade my Fedora installation from i686 to x86_64. Everyone says you should just reinstall; they probably do not value their customizations. My system has been upgraded from Fedora Core 3, and has been moved on a multitude of different hardware. Preserving /home, /usr/local, /opt, /etc is still not enough, you then have to be sure everything you had installed is there again: big job (maybe you do not have the installation package anymore). I can't describe all the details for the cross-grading, but I want to try to be helpful for others wanting to try that. The transition was a F14-i686 to F14-x86_64 (end-of-life!). On a second step there will be an upgrade to F15 and F16. The system had many rpms from additional repos (fusion, atrpms, java-sun from jpackage, a few rpms from some vendors). The system was running the latest x86_64 (!) kernel for F16 (!!) . For the record: running an x86_64 kernel instead of the i686.PAE works perfectly, and it is better for speed and stability (why Fedora did not push this feature I do not know). I also discovered that running a F16 kernel on F14 is OK; yum complains about some dependencies (module-init-tools, IIRC), but it solved some hibernation issues. FIRST STEP: TOTAL FILE-LEVEL BACKUP OF THE SYSTEM (rsync to another machine; this is a habit for me) I've actually done the migration by yum in a graphical shell. (!) So we already have collected a good quantity of "no, do not do that" things. :-) The most difficult part came now. I wanted to start installing x86_64 stuff in parallel to i686 and it was not exactly clear to me on what base rpm and yum decide the arch. The final trick was, IIRC, just install rpm.x86_64; it appears to contain the "info" about the running architecture. Some things were required to be installed at the same time (mostly glibc). I had a complete local mirror of F14 packages to avoid going to the network. The "file `which rpm`" command started to say that it is an ELF64, so I moved to yum. This is more complicated because it takes some Python dependencies with it. I repeated tried "rpm -ihv --test" and added more and more dependencies on that command until it succeeded. Then "yum clean all". In this phase I discovered that if you have a 64bit rpm and a 32 bit yum the rpm database gives you strange errors. Every time you switch from one tool to another the database appears to be corrupted, but it isn't. The solution is to just remove a few tmp files: see RH bugzilla 553998. At this point I started to use yum to install x86_64 stuff. Started with small things (grep, bash), then moved to things with more dependencies and then started to involve heavy things (for example, evince will drag some GNOME, and so on). As I was running KDE, I used the GNOME desktop as a guinea pig. :-) Having both i686 and x86_64 version fails in some cases because the shared files are not identical. I had to remove the i686 version in some cases and just install the x86_64 one. Some "rpm -e --test" and "rpm -e --nodeps" were necessary to understand how big was the risk of breaking the system at every step. A really big issue: i686 rpms from atrpms which I was not able to move to x86_64 because the f14-atrpms repository has been deleted from the net. Aaaargh. Only a couple of stale mirrors were still there, I catched everything from them, and also had to downgrade versions or remove some stuff and take a note of reinstalling it later (maybe on F15). Why doesn't atrpms have an archive repository like fedora??? For safety, I installed the rpms for KDE by logging in via ssh. The kde environment was still running and it was unaffected by the process, anyway. Some bash tricks involving "rpm -qa", "grep" and "yum install" took care of installing as much as possible as x86_64, removing i686 when necessary to resolve (apparent) conflicts. It is fun to see there are -devel packages for both archs. At the end I had an almost completely biarch system. So reboot. (No change to grub, the kernel is still f16 x86_64). The boot goes well. X doesn't start: no driver. I had a /usr/lib path in /etc/X11/xorg.conf, which I had to replace with /usr/lib64. Solved. But KDE doesn't start. Hmmm. GNOME does, XFCE does, fluxbox does. After some deep investigation, the solution was to just remove the content of /var/tmp/kdecache-*, which is probably saved in an architecture dependent format. As a cleanup, I started to remove i686 stuff. My idea is to only keep some libs for compatibility with i686 only applications. Started doing some of the work manually (yum remove and be sure you are only removing stuff you have on x86_64 too). Then wrote more bash one-liners: list all the rpms, find everything i686 which is not dependent on anything else and exists in x86_64 format too; remove the i?86. Repeat it a few times to escalate deeper in depend

The other "downside" is that the NM GUI (at least on KDE) doesn't allow for adding a second IP address. Needs to be done manually. Yeah, I tried having an alias file every which way imaginable, and just couldn't get it to work while having NetworkManager and DHCP run things. NM, and DHCP, are very convenient, even if, for all practical purposes, the assigned IP addresses are static. That does make things easier. Looks like I'll just go with executing "ip addr add" manually, when I need to bring up a second IP address. It's not really the end of the world, but it would've been nicer if it were automated. I think that NM has a post-* script somewhere, that gets executed when it brings up an interface with a DHCP- acquired IP address, that I can stick that into… pgpZJ9DKrvni4.pgp Description: PGP signature -- users mailing list users@lists.fedoraproject.org To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?

help installing f16
Hi all, I downloaded the f16 install DVD (6.5 hours) and have been trying to install it to an lvm partition that is part of a Xen box. Two days later I'm asking for help. Hope this doesn't sound like a rant but I'm very frustrated. This is a description of what I've been going through with a request for help at the very basic level of "Set Up your Drives". I can't use livecd to install because that method won't install into a virtual environment and shutting down every other vm just so I can boot "bare metal" takes down my entire operation: no dns, no mail, no web, no firewall, no databases. Nulla. Nada. Squatalucci. Out of business while a livecd install takes place. I'm not the only user here. That means I take down every other business, too. Wow! Talk about regression. I feel like I'm in the way-back machine or in need of invoking the "Help me, Mr. Wizard" invocation what with the ansi language and keyboard selectors. Haven't seen those in many, many years, maybe a decade. Then there is the disk setup. Makes that good old p.o.s. called disk-druid look useful. Totally screwed up the disk. Replaced a functional msdos partitioning scheme with GUID partitioning that creates a header at the very end of the disk which renders fdisk useless and requires kpartx or parted to be used instead. Problem is that kpartx is also a p.o.s. and parted is half brain dead. e.g. parted requires start and end parameters for a partition but does not provide any info about the disk's layout. Had to use the now deprecated fdisk to find that info. Had to use dd to fill 10G with dev/zero to destroy the GPT but the new disk manager still managed to find a non-existent partition table which meant there was no free space on the empty drive. OK, finally made it to the disk setup where the 2 drives, 10g and 1g, are detected and automatically placed into the right side box and the arrows for moving them left are greyed out and unusable. Fine. 10g is the drive selected for the bootloader. Press . Created 10g mount point / ext4 and 1g swap. Press . "Partitioning Errors. You have not created a bootloader stage 1 target device". Just peachy. What does it want? Where is that done? Tried adding a /boot partition that will never be used but that, too, proved pointless. Has anybody succeeded in installing from "install media" as opposed to "livecd media"? Pointers? Hand holding? Advice? etc. (just don't rick roll me). Thanks, Mike Wright p.s.

AFAIK there is a complete rewrite in progress until that add "noefi" or "nogpt" as boot param the need for a kernel-param to decide between DOS/GPT is simply broken by design, but however you need it _ the main problem here is the useless error message a F15 install media has a different message where you can successful find with google the "noefi" boot param for the install DVD signature.asc Description: OpenPGP digital signature -- users mailing list users@lists.fedoraproject.org To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
