Either way (with suitable changes to grub.conf). > Second question - do the two VGs have different names? Yes. Even when the boot drive is set in the BIOS to be the drive containing the Volume Group to use, VolGroup01, all Volume Groups are recognized, and then VolGroup00's volumes are activated. I see that nash has started. In the initrd, the nash script "init" contains the offending settings. I suppose I need to use mkinitrd to fix this, so that VolGroup01 (and also VolGroup00 which contains the swap partition) is activated. (I'm baffled as to why `grep -rI nash .` in the unpacked initrd would cause endless spew of RETURN characters into any active window, as if from the keyboard, making the computer unusuable and also hard to reboot. "-rIl" spews something else, maybe spaces, not quite as hard to reboot.) -- ____________________________________________________________________ TonyN.:' <mailto:tonynelson@xxxxxxxxxxxxxxxxx> ' <http://www.georgeanelson.com/> -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
