App2sd link2sd how to show mount view 2nd micro sd card ext2 partition



  • Question :App2sd link2sd how to show mount view 2nd micro sd card ext2 partition

    I had loaded twrp recovery (fastboot boot twrprexovery.img) in bootloader mode and installed SU and rooted and then installed app2sd and link2sd apps.

    I had partitioned my 64 gb memory card 30gb fat32 and remaining 32 gb. As ext2 and then when I tries to view partitions in android 5.1.1 settings>storage it show only one fat 32 partition in sd. Card and not second sd card for ext2

    As I want to install 2nd sd card and from recovery or adb pull take NANDROID image backup Of second partition backup in cloud and want to see pace and access file system so that I can recover if any thing goes wrong or memory card got corrupted

    My queries:-

    1. How can I view second partition of external micro sd card partiton through file manager or in setting> storage

    2. Can I be mounted In boot.init through any aap

    3. App2sd auto created a mount script to run through recovery to mount the ext2 partition how to run it in twrp so I have to run through install

    4. How to take NANDROID image backup of system boot recovery internal (userdata partition) and external sdcard 1st and 2nd partitiion and save it in usb drive or cloud storage through adb pull or twrp. Or any other apps how can these files be secured in password or encrypted in cloud

    5. As app2sd pro or link2sd plus card link apps and moves lib hex odb files to which files which are randomly access should be not moved to sd card and should be left in internal memory.

  • TWRP is not compatible with Link2SD, therefore one must manually mount MicroSD Card 2nd partition each time before TWRP backup/restore is started.

    One can do this from - TWRP menu - Advanced - Terminal

    mount /dev/block/mmcblk1p2 /data/sdext2
    

    TWRP backup will include 2nd partition in data.ext4.win as regular directory sdext2 therefore it is important to double check /data/sdext2 is actually mounted before restoring process is started, otherwise TWRP will try to restore all files into phone storage /data instead (and probably run out of disk space)

    If you prefer to create separate TWRP backup files for 2nd partition (instead of mixed userdata) this can be done from TWRP backup menu.

    It requires modified TWRP recovery. Unpack twrp.img ramdisk with AIK and add new entry in /etc/twrp.fstab

    /dev/block/mmcblk1p2  ext4  /sd  flags=display="MicroSD 2nd Partition";backup=1
    

    This will show you separate entry in TWRP backup menu and create separate sd.ext4.win backup files
