From mboxrd@z Thu Jan 1 00:00:00 1970 From: Eric Cooper Date: Fri, 17 Sep 2010 12:44:38 -0400 Subject: [U-Boot] request for ubifs recovery support Message-ID: <20100917164438.GA4226@localhost> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de I've configured my device (a Seagate DockStar) with just two NAND flash partitions -- one for u-boot and one for the Linux rootfs. This has some nice advantages: it maximizes the available flash space, and allows the Linux distribution's own tools to install new kernel and initramfs files without having to know about flash partitions. But I just discovered that it has a fatal disadvantage. My device can't reboot when the ubifs is corrupted, which happened today after a power failure: UBIFS: recovery needed Error reading superblock on volume 'ubi:root'! Ubifs includes recovery code, but since u-boot treats it as a read-only mount, this is never performed. Once I booted Linux, everything was fine. I'd like to request that the read-only flag be removed (at least to allow recovery) so that the ubifs-only scheme can be used reliably. -- Eric Cooper e c c @ c m u . e d u
