I recently came across the idea of mount binding in Linux. I am wondering if I can mount bind the /storage/emulated/0/Android to /storage/sdcard1/Android. Will this extend my internal storage? Should I partition my sdcard into 2 partitions with one being ext2 file system for this to work? Will apps whose data is stored in the internal memory work if I do this and then move the data to the external sdcard? Where will the apps I download in the future store their data?

How to show configure mount ext2 ext4 formatted SD card partitions in android file manager? As fat32 fiile system don't support files more than 4 gb I have to take backup before after rooting for safety backup of system boot userdata through twrp or DD if command which saves files in sd card and the files of twrp images of userdata mmcblk0 is more than 8GB-15GB and it requires to format sd card to ext2. As in adb shell or fastboot we can write on ext2 formatted partion is micro sd card But ext2 ext4 file system ( I formatted partitioned with mini partition tool) is not readable in windows PC and when I inserted booted android 6.0 and open the android self file manager or xplore or.solid explorer or settings storage without rooting it shows only reads the first partition of fat32 but it don't shows the second partition there and.even in settings storage as it's not mounting reading the ext2 ext4 partition and mounting it. Firstly I have to read the sd card and copy the images file on pc which is unreadablle unmountable in android and windows both I know we can do adb pull command and copy it to pc directly but I want to change file system of external sd card to ext2 or ext4 so that if I download big videos or create any big size files more than 4gb then it can save it fastly and secure in ext2 or ext4 file system My queries :- Q1. Can we use configure SD card second partition ext2 or ext4 formatted for moving apps as it move default to first partition through SM or PM commands can second app be used only in link2sd can't we manualy through adb shell configure it or format first or second partition as internal memory Q2. So my question is how through any app or adb shell command I can mount or make sd card second partition ext2 or ext4 file system mountable readable in my android 6.0 mobile phone. Any way to edit FUSE bind in boot.init without rooting or any other way apps to make it readable.kindly guide steps as I am novice new to android adb and programming commands Thanks for your precious time advice opinion suggestion and sharing knowledge.

I have a android mobile with gingerbread 2.3.4 installed. I want to know if my device(kernel) supports ext2 filesystem. Is there any terminal command to check the support for ext2 filesystem ?

After making a 1744MB ext2 partition on my 4GB MicroSD with the Aparted app (since my Windows SD slot is broken) and trying to select ext2 when I start Link2SD I always get the error: > Mount script cannot be created > > mount: Invalid argument I tried to delete busybox from system/xbin to install a newer version, but /system won't mount as Read-Write. How do I fix this? EDIT: I'm using KingRoot EDIT 2: So I made an ext4 partition instead, and now it says > Mount script cannot be created > > mount: Read-only file system and I tried running e2fsck -fpDC0 /dev/block/mmcblk1p2 in terminal emulator (seen here as a solution) and I got the output: ` e2fsck: Internal SD card is not found, now mount manually e2fsck: save_log_to_file error /dev/block/mmcblk1p2: |== /dev/block/mmcblk1p2: |============================= /dev/block/mmcblk1p2: |=============================` `/dev/block/mmcblk1p2: 12/116400 files (0.0% non-conti guous) 16193/465096 blocks`

As the subject indicates, does Android support any of the Extended File Systems ("ext", "ext2", "ext3" and "ext4") for removable storage cards (such as Micro SDXC storage cards)? Android is a Linux-based operating system, so surely such filesystems would be supported? My question relates to both Android 4.4-4.4.4 ("KitKat") and Android 5.0-5.1.1 ("Lollipop"), as I am just about to buy the Sony Xperia Z Ultra which runs the former, but has an upgrade available for "Lollipop"... The reason I ask is because Extended File Systems have a number of distinct advantages over Microsoft filesystems, and I do not use Microsoft Windows-based operating systems at all (well, at work I do - but personal stuff can't be used with their computers...), so it's only logical to utilize Extended Filesystems where possible, for the technical advantages.

I have a rooted LG-D520 (Optimus F3Q) running Android 4.1.2. The internal memory that came with the phone was so small that I installed an 8GB SD card. I formatted it using MiniTool Partition Wizard with 1.5GB of ext2 (the rest is FAT32). Using Link2SD I've moved many of my apps over to the ext2 partition. I do *not* have a ton of apps (they just seem to keep getting bigger), yet I only have 5% space left on the ext2. My internal memory has 27% left (355MB), but I've had to delete a lot of stuff to make room. I'm only using a small portion of the 5.9GB FAT32 partition, so I'm wondering if... 1. I can increase the size of the ext2 beyond 1.5GB. Is there a maximum size and, if so, what is it? Can I repartition without losing my apps & data or do I need to backup, format and start over? 2. I can add another ext2 partition to my SD card and load apps into there. Can you have multiple ext2 partitions and, if so, would that work with Link2SD? 3. Are there any other options ? This has been a frustrating endeavor and it's unbelievable the lengths you have to go to in order to do basic stuff on an Android phone, so I'd appreciate any advice.

Does anyone know how I can enable ext2 or ext3 partitions on my LG Optimus V? I have already partitioned my 16GB SD card to 14.5 GB FAT32 and 500MB ext2. When using Link2SD it gives me a mount error. I am rooted but have not flashed any ROMs yet.

So I am attempting to mount an ext2 partition on a pen drive to a tablet I have, the actually mount is done with: adb shell "mount -t ext2 /dev/block/sdb /mnt/ubuntu" This works fine and ubuntu is a folder I already created on the android device. Now when I go to access the files on that partition (the rootfs of a ubuntu install in fact) I end up with: root@android:/ # ls /storage/ubuntu lstat '/storage/ubuntu/android' failed: I/O error lstat '/storage/ubuntu/bin' failed: I/O error lstat '/storage/ubuntu/boot' failed: I/O error lstat '/storage/ubuntu/dev' failed: I/O error lstat '/storage/ubuntu/etc' failed: I/O error lstat '/storage/ubuntu/external_sd' failed: I/O error lstat '/storage/ubuntu/home' failed: I/O error lstat '/storage/ubuntu/lib' failed: I/O error lost+found lstat '/storage/ubuntu/media' failed: I/O error lstat '/storage/ubuntu/mnt' failed: I/O error lstat '/storage/ubuntu/opt' failed: I/O error lstat '/storage/ubuntu/proc' failed: I/O error lstat '/storage/ubuntu/root' failed: I/O error lstat '/storage/ubuntu/run' failed: I/O error lstat '/storage/ubuntu/sbin' failed: I/O error lstat '/storage/ubuntu/sdcard' failed: I/O error lstat '/storage/ubuntu/selinux' failed: I/O error lstat '/storage/ubuntu/srv' failed: I/O error lstat '/storage/ubuntu/sys' failed: I/O error lstat '/storage/ubuntu/tmp' failed: I/O error lstat '/storage/ubuntu/usr' failed: I/O error lstat '/storage/ubuntu/var' failed: I/O error

I've created a 512Mb partition on my HTC Desire's (running LeeDroid) SD card to store apps. When I used Windows, I'd never had a problem with this partition becoming read-only, unreadable or corrupted. Since I switched to a Mac, this partition got corrupted several times. Somehow, I thought it was LeeDroid's fault, and didn't blame it on the Mac. I installed Cyanogenmod on the Desire to overcome this problem, but the ext2 partition on the card still kept getting corrupted. I read on the Cyanogen's forums that Linux and OSX automatically mount the ext2 partition when the phone is plugged in, causing the partition to become corrupted, and then this made sense. Question: Is is possible to prevent OSX from automatically mounting the ext2 partition on Android phone's SD card?

I don't want to use fat32, I want use the more stable ext2.

I have a huawei u8160 running Cyanogenmod 7.2. when I restart my phone I have to remount the sdext myself using terminal emulator. su mount -t ext2 /dev/block/mmcblk0p2 /data/sdext2 but now it returns : mount : mounting /dev/block/mmcblk0p2 on /data/sdext2 failed : invalid argument so I want to know how can I mount it again?

I am wondering if the lag fix proposed by xda-developers could harm the device in anyway. Quote from Google Code "Original use was for 'One Click Lag Fix' for the Samsung Galaxy S series, to create a loopback EXT2 device on top of Samsung's RFS in order to improve response time for applications." Link to forum page about this: here . How does it work exactly? What does "create loopback EXT2" mean? I know the forum post clearly states it's been tested on a huge number of devices and it's working, but I want to understand what it does exactly and if there is any compromise by installing it? Thank you.
