There's a patch for btrfsprogs which introduce a new command: btrfslabel https://patchwork.kernel.org/patch/70701/ You might need to make some changes to merge it with current version, but the userland-only patch works great for changing unmounted btrfs filesystem. It works even without the kernel-side patch. -- 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
