https://bugzilla.redhat.com/show_bug.cgi?id=807905 Currently if you specify the blocksize parameter to mkfs-opts with a btrfs filesystem, then it fails, because mkfs.btrfs interprets the -b option as meaning filesystem size. The first patch fixes this by disallowing blocksize (it cannot be mapped meaningfully into btrfs parameters). The second patch adds the full /sbin/mkfs.btrfs utility to the

Hi, Question is pretty simple: "How to change node size and leaf size on previously created partition?" Now, I know what most people will say: "you should''ve be smarter while typing mkfs.btrfs". Well, I''m intending to convert in place ext4 partition but there seems to be no option for leaf and node size in this tool. If it''s not possible I guess

Hi, The following patches add support for ext4 and btrfs to PV-GRUB. These patches are taken nearly verbatim from those provided by Fedora and Gentoo. We''ve been using these patches for the PV-GRUB images available in EC2 for some time now with no problems. Changes from v1: - Makefile has been changed to check the exit code from patch - The btrfs patch has been rebased to apply
