From dc6cc040169a3f29d0126c24d65d5e7b6c479ab8 Mon Sep 17 00:00:00 2001 From: Jo-Philipp Wich Date: Sun, 16 Oct 2016 01:59:44 +0200 Subject: [PATCH] config: ext4: increase x86 rootfs size to 2GB to support online resize2fs The current default rootfs size of 256MB in conjunction with 4K blocks produces an ext4 filesystem which lacks the appropriate amount of backup GDT entries to support online-resizing. For x86 targets, increase the default rootfs size to 2048MB which allows online resizing the filesystem to up to 2TB which is the current theoretical maximum for LEDE, due to missing GPT support on the root block device. Note that the filesystem artefact will not occupy 2GB on the build system as the make_ext4fs utility uses sparse files to generate the filesystem images, so the actual disk usage is much lower. Furthermore the filesystem images are gzip compressed, shrinking them to only a few megabytes on the download server.
