Re: [FIXED] Re: [gentoo-user] newbie livecd installation dual boot problems
I am a jfs user as well and would recommend (especially on a laptop) to add the line that was recommended above: root (hd0,1) kernel /boot/kernel-genkernel-x86-2.6.15-gentoo-r5 root=/dev/hda2 to the bottom of your /boot/grub/grub.conf. Often when I hard reboot (power failures, etc), reading the bootsplash stuff seems to take priority over checking the fs. The simple solution for me is to leave a non-nonsense 'failsafe' line in grub and boot into it so that my fs gets repaired and then reboot normally. You could achieve the same thing by editting the grub command at boot, but this seems like a simple alternative. HTH. -- Travis -- gentoo-user@gentoo.org mailing list

I wiped the debian installation, and carefully made sure that Gentoo wasn't going to wipe out the winxp partition which is the first. I made /dev/hda2 one partition for gentoo, and it's JFS. The installation process finished without errors, but when I reboot the machine I have 2 problems: (i) the grub installation doesn't show the winxp entry (easy enough fixed, but still an installation bug) (ii) gentoo starts booting, but fails when trying to mount the root device. Determining root device... Mounting root... mount : Mounting /dev/hda2 on /newroot failed: Invalid argument !! Could not mount specified ROOT, try again !! The root block device is unspecified or not detected. The grub boot lines are: root (hd0,1) kernel /boot/kernel-genkernel-x86-2.6.15-gentoo-r5 root=/dev/ram0 init=/linuxrc ramdisk=8192 real_root=/dev/hda2 initrd /boot/initramfs-genkernel-x86-2.6.15-gentoo-r5 This was how the installer set it up, so what needs to change to fix it ? thanks! From the gentoo handbook located here http://www.gentoo.org/doc/en/handbook/handbook-x86.xml?part=1chap=10 Note: If your root filesystem is JFS, you must add ro to the kernel line since JFS needs to replay its log before it allows read-write mounting. I don't use JFS so I dobn't know exactly how to do it but this is what I got from searching google. Kirby -- gentoo-user@gentoo.org mailing list

Jim I have tried both rw ro since I had 2 different replies about this problem - unfortunately both failed with the same error as before. I use JFS since I find that it's fast stable too like Reiser. I tended to use a scattering of filesystems in the past so that I had experience of them all, but I'm gravitating towards JFS mostly now on my servers. I've done extensive speed testing using IOZone (http://www.iozone.org/) and for our systems, our drives, our application I just liked jfs. Not a lot between them all though apart from speed of file creation/deletion. thanks Trevor.

Re: [gentoo-user] newbie livecd installation dual boot problems
I am assuming the kernel is built with JFS support compiled in and not as a module. I am not a genkernel user but couldn't you boot the machine like this, root (hd0,1) kernel /boot/kernel-genkernel-x86-2.6.15-gentoo-r5 root=/dev/hda2 This will test if it's a kernel problem or a boot splash problem.

Jim wrote: evor. Did you try to boot from the livecd, or another boot cd, and see if you can even mount your JFS partition? Jim Yes I have. It mounts fine when using the livecd to boot from. I can read/write to it no problem, and all the file structure is there. I've had a look at the bootlog with dmesg, and I'm now thinking that the installed kernel doesn't have JFS modules/support in it..the boot identifies the partitions (hda1, hda2 etc), but then it tries to mount hda2 with almost every fs APART from my beloved jfs. It's tried Reiser, XFS, ext2, ext3, vfs - everything but jfs. OhI don't fancy another 6 hour install!!

Kirby I gave that a go , but still no luck. I'm having one of those days. I think I'll reinstall using reiser - I thought that jfs would be fine since the installer gave me the option. I assume that had I done a network install that I probably would've got a kernel with jfs ? My install was completely from the live cd. thanks!

I'll have to check it out, as I must've left out 70% of the modules to get that compile time :0 Yeah, I've been swapping between Gnome KDE just as much as I swap between filesystems :) At the moment I've been using KDE for about 3 months after being pretty much gnomed for 2 years or so.
