It seems that the problem is when using big partitions and GPT. If I reduce my partition sizes and use a normal dos partition style grub installs without problems. When using GPT the error occures. I use a 1MB boot_grub partition for embedding the grub bootfiles. I use the following scheme (for example):
""" $> parted /dev/sda print Disk /dev/sda: 3001GB Sector size (logical/physical): 512B/512B Partition Table: gpt Number Start End Size File system Name Flags 4 1049kB 3146kB 2097kB bios_grub 1 3146kB 2151MB 2147MB raid 2 2152MB 2688MB 536MB raid 3 2689MB 45.6GB 42.9GB raid """ Does grub-2 from ubuntu not support GPT partition style? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/681535 Title: Auto-detection of a filesystem of /dev/md0 failed.
