If you mount the filesystem with `-t ext4dev -o extents' then create some extenty files, then unount it and then mount it without `-o extents', the driver will then refuse to create extenty files. IOW: you need to give it `-o extents' each time. That seems fairly pointless. In fact, if I'd created the fs with `mke2fs -O extents' (which doesn't work at present) then I'd expect it to use extents from thereon after, without requiring `mount -o extents'. - To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
