I run OpenWrt on x86 with ext4 image, but recently I noticed my system is being mounted in read-only I ran e2fsck/fsck sometime it finds some errors and fixes them, and sometimes it shows that the filesystem is clean
I also enabled the file system check from the web GUI but I noticed some errors in the kernel logs during the boot
[ 4.287271] EXT4-fs (sda2): mounted filesystem without journal. Opts: (null)
[ 4.294368] VFS: Mounted root (ext4 filesystem) readonly on device 8:2.
[ 10.915386] block: attempting to load /etc/config/fstab
[ 10.924471] block: check_filesystem: /usr/sbin/e2fsck returned 8
[ 11.305190] EXT4-fs (sda2): re-mounted. Opts: (null)
[ 11.323376] mount_root: switched to extroot
[ 11.406749] EXT4-fs (sda1): mounted filesystem without journal. Opts: (null)
strangely enough when the fsck shows that the system is clean. running mount -o remount,rw /
is enough to re-mount in r/w
I have been debugging this for a while with no avail, and I do not want to do a clean install as I have a lot of configuration on the system
