GRUB 1.99 Released With Support For ZFS and BtrFS

Posted by CmdrTaco on from the boot-grub-joke-goes-here dept.

kthreadd writes "GNU GRUB has been updated to version 1.99. Among the many improvements are support for two new filesystems, BtrFS and ZFS. For Linux users this means that it's now possible to move to BtrFS entirely and not use it only for non-bootable volumes."

    Until it supports booting from paper tape or punch card, I'm not going to trust it 100%

    Ext4 is a more error-resistant (safer) and potentially faster Ext3. If you don't know what BtrFS is good for, you don't need to use BtrFS (although it could become a mainstream filesystem some day).

    Put another way, ext4 is a replacement for ext3, whereas btrfs is a replacement for zfs.

    I think you mean that btrfs is a replacement for ext4. Maybe I'm naive and a bit reactionary but I'm just not seeing FreeBSD and Solaris switching to btrfs just because the Linux crowd says it's the greatest thing since sliced bread...

    To obtain all of the ext4 performance, tweaks, and reliability benefits, you MUST perform an ext4 format.

    That's not entirely correct. With two commands, you get a full conversion from ext3 to ext4 without a reformat, leaving your data in place:
    tune2fs -O extents,uninit_bg,dir_index /dev/DEV
    e2fsck -fDC0 /dev/DEV

    (On an unmounted filesystem, obviously. Source. )
