Message-ID: <Pine.A41.4.64.1009211500110.1245260@stalin.acc.umu.se> Date: Tue, 21 Sep 2010 15:28:51 +0200 (CEST) From: Bo Brantén <bosse@....umu.se> To: linux-ext4@...r.kernel.org Subject: uninit_bg compatibility? Hello, when writing new files to an ext4 file system using the Windows driver fsck will later complain "Group descriptor nn checksum is invalid" and I think that is because it used an yet unused block group without knowing that they can be marked as uninitialized. So I thought a simple patch would be to mount the file system read-only if that feature is in use untill the driver is updated with full write support but I can't find the flag to use, there is no EXT4_FEATURE_RO_COMPAT_UNINIT_BG so I thought I ask here if anyone could clear this out. -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
