OpenWrt 21.02.0: no filesystem check before mounting although enabled

I'm running Openwrt 21.02.0 r16279-5cc0535800 on a ZeroPi.

My SD-card has the following layout:

MODEL  SIZE NAME           TYPE FSTYPE LABEL       MOUNTPOINT
      28.3G /dev/mmcblk0   disk                    
        20M /dev/mmcblk0p1 part vfat               
       104M /dev/mmcblk0p2 part ext4   rootfs      /
      28.2G /dev/mmcblk0p3 part ext4   DATA-ZEROPI /data

Regarding the 3rd partition the file /etc/config/fstab contains the following lines:

config mount
	option device '/dev/mmcblk0p3'
	option target '/data'
	option fstype 'ext4'
	option options 'relatime'
	option enabled_fsck '1'
	option enabled '1'

Among others the following packages are installed:

  • block-mount
  • e2fsprogs
  • kmod-fs-ext4
  • libext2fs2

During the boot process the 3rd partition is properly mounted, but (although fsck is enabled) not fscked. Why? Did I miss anything?

try enabling fsck in the general mount options (the first option block in the file)

This option was enabled all the time.
