Hello ,
...that the mkinitrd/mkinitramfs-script will sniff around your system... to boot a system that doesn't have LVM
Luca said in an answer to this message: "LVM is much more than a partition type," It is clear to me that the mkinitrd is dependant upon what I install. But it is not clear to me what in the installation of Fedora Core characterizes the system as having LVM (or not having LVM). What is a system that does have an LVM and a system that does NOT have LVM ? Suppose somebody goes to an unknown fedora machine and want to know if there is LVM on that machine. How can he know it? is the existence of LVM partition is a precondition ? meaning, if he runs "fdisk -l |grep LVM" and doesn't get anything than it is not LVM , and if there is an LVM partition than it is LVM machine? or is it not enough to to this check and there should be some another check ? The thing is that I made 2 installations of Fedora Core 5; in the first I chose to format a partition as LVM and in the second I did not. Is this is what causes the initrd to have the lvm commands in the first case and not to have them in the second place ? because I don't remeber that elsewhere in the installation process that I did select anything connected with LVM (there is ofcouse the manual layout in which I chode /dev/VolumeGroup... in the first case). regards, MR On 9/23/06, Aleksandr Koltsoff <czr@iki.fi> wrote:

Similar story for software raid. This means that if you take the initrd and try to boot a system that doesn't have LVM you're doing something wrong. initrds are not supposed to be portable, however this will of course depend very much on the distribution. Hope this answers your question. ak. _______________________________________________ linux-lvm mailing list linux-lvm@redhat.com https://www.redhat.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
