Hi, Perhaps you can describe the steps used to create the LVM volume, along with version number of tools. Let me see if the error can be recreated in qemu. > >> >> Yes, it should work out of the box, although there is a small catch. >> If you're using raid5/raid6 and one/two of the disk is missing or >> corrupted, you need to add module raid5rec/raid6rec using the --module >> option in grub-install. >> > > Just curiosity - why it's in separate modules ? It's caused by size limitation of mbr, which is normally 63 sectors. When you use the following modules: biosdisk pc reiserfs lvm mdraid raid6 raid6rec The size of core.img would exceed 63 sectors, so that it can't be installed to mbr. -- Bean _______________________________________________ Grub-devel mailing list Grub-devel@gnu.org http://lists.gnu.org/mailman/listinfo/grub-devel
