Really? How do you know it's 256 MB? > # fdisk /dev/sda > WARNING: GPT (GUID Partition Table) detected on '/dev/sda'! The util fdisk > doesn't support GPT.

You can check again if you want, using "parted /dev/sda print" (just in case it's really fdisk problem). > Maybe it's possible that I just mkfs.btrfs /dev/sda and it will set up -only- > the remaining space, but I'm afraid that this may destroy my OS.

Ubuntu Natty's grub2 has btrfs support, but It's still in alpha stage though. Don't know about Debian. At this point it's easiest if you use ext3/4 for /boot, and use btrfs only for "/". -- Fajar -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
