What kernel did you boot? experimental or gentoo ? Problem existed with both kernels! Problem is still in the 2004-02-04 LiveCDs. At the moment it is impossible for me to test Gentoo since LVM is integral to the way I manage my disks. Have you tried 'insmod lvm-mod && insmod dm-mod' ? (along with possibly a 'vgmknodes') Seems to work for me... *** Bug 43704 has been marked as a duplicate of this bug. *** have you tried the 2004.0 livecd? *** Bug 43578 has been marked as a duplicate of this bug. *** alan, well? I have'nt managed to try the 2004.0 LiveCD yet (first attempt resulted in a coaster). Am re-downloading the ISO image even as I speak, will burn it and try again later today and report the results. Using the 2004.0 LiveCD, I ran vgchange -a y before running vgmknodes, and all the logical volumes were finally loaded into the /dev tree. However, while going through the Gentoo installation, I forgot to add lvm to my use flags, so LVM was never installed. When I rebooted, the kernel couldn't load any of the LVM volumes and failed. Resolving this will take yet more time I'm not willing to devote to Gentoo, so I gave up again. And this is really where the bug lies. LVM may be supported by Gentoo, but very poorly, and with no effort to inform the user how to do so. The LVM modules should be automatically loaded by the LiveCD, users should not have to go fetch for them. Any existing LVM volume group(s) and logical volume(s) should be automatically detected by the LiveCD during boot and made available to the user. And the installation instructions should mention that LVM support needs to be specified while setting up the base system. But none of this is done! All we get is some obscure statement that LVM is supported by Gentoo, nothing else. LVM volume group correctly handled by 2004.0 Universal LiveCD. Bug report can be closed now. Note that there was no need to run vgmknodes. Frank, you may be right. In fact, LVM isn't covered in the installation manual. We think that a user want's to use LVM should have the basics to create such volumes. Describing the strategies with multi-device-volumes surely is too much for an installation manual. Alan, thanks for testing. I'll set this Bug to WORKSFORME. That way we're able to collectively keep it in mind. OK, I used "modprobe dm-mod" and it worked :) |
