Dear fellow Fedora users, I just upgraded from F15 to F17, but it won't boot--says it can't find the root filesystem, which is on a logical volume in an LVM volume group. (See boot messages below.) For the record, F15 booted just fine with this structure. I know this problem--or at least very similar problems--have been discussed many times, both in this mailing list, and also in FedoraForum.org. But none of the suggestions I have seen so far in either of those places seem to fix my problem. I did try one suggestion found in the Fedora docs (detailed below) which got me past the first "bump", only to run into a second problem--this one apparently involving udev. So I'm stuck with an unbootable F17 system. If anyone has any insight into what might be going on, I'd be very grateful. Thank you very much. --- boot messages --- Cannot open font file True ata_id[237]: unable to open '$devnode' ata_id[238]: unable to open '$devnode' dracut Warning: Unable to process initqueue dracut Warning: /dev/FedoraVolGroup/RootLogVol does not exist dracut Warning: /dev/mapper/FedoraVolGroup-RootLogVol does not exist Dropping to debug shell. dracut:/# If I then enter 'lvm vgchange -ay', followed by 'exit', the system begins to boot, but then encounters udev errors, and aborts to emergency mode: [ 1652.284204] udevd[678]: invalid rule '/etc/udev/rules.d/55-hpmud.rules:31 [ 1652.299298] udevd[678]: unknown key 'sysFS{idVendor} in /etc/udev/rules.d/55 . . .
