Check internal storage for errors

In case this helps anyone, these are the steps I took to check internal storage for errors:

1. In Android, get the mount points for /data and /system
   
   
   

   Code:

   
   

   ---

   $ su
$ grep /data /fstab.qcom
/dev/block/bootdevice/by-name/userdata      /data        f2fs    rw,discard,nosuid,nodev,noatime,nodiratime,inline_xattr,inline_data  wait,check,encryptable=/dev/block/bootdevice/by-name/metadata
$ grep /system /fstab.qcom
/dev/block/bootdevice/by-name/system        /system      ext4    ro,barrier=1                                        wait

   ---

   
   


2. Boot to recovery (TWRP)


3. Unmount /system, just to be safe
   (You can use adb shell or the TWRP terminal)
   
   
   

   Code:

   
   

   ---

   umount /system

   ---

   
   


4. Check /system for errors using e2fsck (since it's an ext4 filesystem)
   (The mount points are a little bit different in TWRP)
   
   
   

   Code:

   
   

   ---

   e2fsck -fv /dev/block/platform/soc.0/by-name/system

   ---

   
   


5. In TWRP, go to Mount, check System, uncheck everything else


6. Check /data for errors using fsck.f2fs (since it's an f2fs filesystem)
   
   
   

   Code:

   
   

   ---

   fsck.f2fs -f /dev/block/platform/soc.0/by-name/userdata

   ---

   
   


7. Reboot
