Hi. Regarding a lvm installation:

Can LILO or GRUB (I prefer and am used to the later) start from a LVM'ed /boot? Can /boot be a separated LV?



Thanks

I dont think that is possible.... most of the grub files (like stage 2) is stored in /boot and Loading lvm before stage 2 is not possible(as far as i know).... Thus the /boot should be a physical partition....

However, you can put everything else as LV.... though making root an LV is not recommended since an LVM error would make the system unbootable....

Hello egregor,

This thread LVM question may be of interest to you.

I agree, wasn't expecting GRUB to have this feature. But it seems LILO has. Thanks

Thanks, this post sheds some light. But let me ask you, did you make /boot within lvm (you said fallowed "README_LVM.TXT")?

-------------------------------------------------------------------------

Then I'm thinking about doing a / and a lvm for other partitions. So, to be sure, I will need an initrd with -L option, so it will be possible to mount the rest of the system?



UPDATE

Installed here with grub and root outside lvm. If it wasn't the help maybe I would still be stuck. Thanks


But this question is still up: can Lilo boot from LVM?

gegechris99

Yes. In file README_LVM.TXT, the example describes the installation of both the root "/" and /home directories in LVM.

So /boot is also in LVM (because root "/" is in LVM). And in this case, you'll need an initrd.gz image file that will be used by lilo during boot.

Of course, follow carelful the instructions in the README file to create the initrd.gz file and update your lilo configuration.

OK.


Thanks

thought i would add in... just so that you would know...

The "new" grub, called grub2 supports booting from LVM....

Do post how all this works out...
