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 u= p -only- the remaining space, but I'm afraid that this may destroy my O= S. You might be able to boot using a live CD and use gparted to resize the current ext4 partition. > > Also, what if I want to set up the whole drive as BTRFS? =A0Could thi= s be bootable, and can the canned Debian kernel load the BTRFS driver f= or boot at install? =A0Or would I boot to the CD, mkfs.btrfs the drive,= then install Debian? =A0Anyone tried this? 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 "/". --=20 =46ajar -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" = in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
