Using fsck in bootloader

————————————————————

来源：Debian 8.1 with Uboot bootloader cannot run FSCK on reboot

原文：

I stumbled across this recently on the BananaPi myself. It’s likely your booting with Systemd so setting FSCKFIX=yes inside /etc/defaults/rcS

Won’t help you. Also /proc is a virtual filesytem, so changes will disappear between reboots.

Setting those kernel options are correct for systemd, but you need to append them to the boot args.

In /boot/boot.cmd I appended fsck.repair=yes to the end of the setenv bootargs:

setenv bootargs "console=tty1 root=/dev/mmcblk0p1 rootwait rootfstype=ext4 cgroup_enable=memory swapaccount=1 sunxi_ve_mem_reserve=0 sunxi_g2d_mem_reserve=0 sunxi_no_mali_mem_reserve sunxi_fb_mem_reserve=16 hdmi.audio=EDID:0 disp.screen0_output_mode=1920x1080p60 panic=10 consoleblank=0 enforcing=0 loglevel=${verbosity} fsck.repair=yes"

It’s important to note you need to re-generate the /boot/boot.cmd before they’ll appear using the following command (it’s at printed at the end of /boot/boot.cmd)

mkimage -C none -A arm -T script -d /boot/boot.cmd /boot/boot.scr

You can can confirm it applied after rebooting with cat:

~# cat /proc/cmdline 
console=tty1 root=/dev/mmcblk0p1 rootwait rootfstype=ext4 cgroup_enable=memory swapaccount=1 sunxi_ve_mem_reserve=0 sunxi_g2d_mem_reserve=0 sunxi_no_mali_mem_reserve sunxi_fb_mem_reserve=16 hdmi.audio=EDID:0 disp.screen0_output_mode=1920x1080p60 panic=10 consoleblank=0 enforcing=0 loglevel=1 fsck.repair=yes
