Zyxel NSA325: fsck rootfs on boot

[smaxer]

Hi everyone,

does anybody know a convenient way to run fsck on the root filesystem while booting into arch arm linux?

I had a damaged rootfs and struggled running fsck on it because it was always mounted rw. I ended up booting the NAS into to stock image and run fsck there. But I'd like that fsck runs every startup.

The only way is to create uinitrd and modify uboot environment to load it at boot, which i wouldn't recommend unless you have serial

Thanks for your answer moonman!

FinIly had some time testing it... haven't built a ramdisk by my self since years so I'm not sure if I'm doing this right:

$this->bbcode_second_pass_code('', '
# cd /boot
# mkinitcpio -g initrd_test.img
# mkimage -A arm -C none -O linux -T ramdisk -d initrd_test.img rootfs.uimg
# reboot

Marvell>> setenv bootargs_linux console=ttyS0,115200 mtdparts=nand_mtd:0x100000(uboot),0x80000(uboot_env),0x80000(key_store),0x80000(info),0xA00000(etc),0xA00000(kernel_1),0x2FC0000(rootfs1),0xA00000(kernel_2),0x2FC0000(rootfs2) root=/dev/sda2 rw rootwait loglevel=8 initrd=/rootfs.uimg
Marvell>> boot
')

The problem is it doesn't work I don't even get an error message - so I'm probably doing something terribly wrong :/

As always any help is appreciated!

Thanks

Mainly? Because that is the kernel command line, and not the arguments for u-boot to load an initrd.

Also, there should be an extraargs, IIRC, that you can use for setting extra bits instead of re-writing the command.

You actually need to alter the `bootm` that is part of the bootcmd_linux. Since you have a serial cable, have a look at `help bootm`

This is my goflex net printenv
$this->bbcode_second_pass_code('', 'sata_boot=ide reset; mw 0x800000 0 1; ext2load ide 0:1 0x800000 /boot/uImage; if ext2load ide 0:1 0x1100000 /boot/uInitrd; then bootm 0x800000 0x1100000; else bootm 0x800000; fi')

This is the original? NSA325 printenv
$this->bbcode_second_pass_code('', 'fw_setenv bootcmd_linux 'setenv bootargs $(bootargs_linux); ide reset; ext2load ide 0:1 $(loadaddr) /uImage; bootm $(loadaddr)'')

You should add one for initrd like my goflex net, good luck

Thanks tomcheng76 and moonman for your help!

I did get it to work with the following settings:

$this->bbcode_second_pass_code('', '
setenv bootcmd_linux 'setenv bootargs $(bootargs_linux); ide reset; ext2load ide 0:1 $(loadaddr) /uImage; ext2load ide 0:1 0x1100000 /rootfs.uimg; bootm $(loadaddr) 0x1100000'
saveenv
')

However without using the if else branch in tomcheng's example. Those commands are probably not implemented in my uboot version...

Thanks again!

Best,
smax
