Filesystem Maintenance

Notes

  • Can only be done within TWRP Recovery either via built-in Terminal or over ADB
  • Ideal to do before a clean ROM flash, after an improper shutdown, and after configuring all apps/copying over all data

Quick-command

Normal

  • Boot into TWRP and immediately run the following
  • This expects the usual partitioning 1)
adb shell 'umount '/data' && umount '/cache' && umount '/sdcard' && fsck.f2fs -f '/dev/block/mmcblk0p30' && fsck.f2fs -f '/dev/block/mmcblk0p23' && e2fsck -y -f -v '/dev/block/mmcblk0p22' && e2fsck -y -f -v '/dev/block/mmcblk0p4' && mount '/data' && mount '/cache' && mount '/system' && mount '/persist' && rm -Rf '/data/dalvik-cache' && fstrim -v '/data' && fstrim -v '/cache' && fstrim -v '/system' && fstrim -v '/persist' && sync && umount '/data' && umount '/cache' && umount '/system' && umount '/persist' && reboot'

firmware Partition

  • Boot into TWRP and immediately run the following
  • This expects the usual partitioning 2)
  • TODO: Fix (maybe need to mount firmware partition before doing fsck?)
adb shell 'mount '/system' && fsck_msdos -p -y '/dev/block/mmcblk0p1' && umount '/system' && reboot'

Unmount Partitions

umount '/data'
umount '/cache'
umount '/sdcard'
umount '/system'
umount '/persist'
umount '/firmware'
umount '/sdcard'

system + persist Filesystem Maintenance

  • ext4
e2fsck -y -f -v '/dev/block/mmcblk0p22'
e2fsck -y -f -v '/dev/block/mmcblk0p4'

data + cache Filesystem Maintenance

  • F2FS
fsck.f2fs -f '/dev/block/mmcblk0p30'
fsck.f2fs -f '/dev/block/mmcblk0p23'

firmware Filesystem Maintenance

  • vfat
  • TODO: May require /system to be mounted
fsck_msdos -p -y '/dev/block/mmcblk0p1'

Mount Partitions

mount '/data'
mount '/cache'
mount '/system'
mount '/persist'
mount '/firmware'

Clear Dalvik/ART Cache

mount '/data'
rm -Rf '/data/dalvik-cache'

fstrim

  • If done immediately after booting TWRP, /data and /cache are already mounted, but /system, /persist, and /firmware aren't
adb shell
mount '/system' && mount '/persist' && mount '/firmware'
fstrim -v '/system' && fstrim -v '/data' && fstrim -v '/cache' && sync
