[Q] /emmc/ wont mount in CWM after encryption - Galaxy S II Q&A, Help & Troubleshooting

CM10 recent install from CM9, which was Encrypted for work email.
Read that you can just format the partition and it will install new roms fine.
Within CM10 I can see /ExtSDCard/ and but /SDCard/ aka /emmc/ in CWM wont mount.
Going further down into CWM, emmc wont mount so it looks like it has installed the rom fine as it boots without a physical SD Card inserted? When trying to mount /emmc/ the log shows the following error "Failed to mount /dev/block.mmcblk0p11" which I assume is related.
I would like to mount and format the previously encrypted internal storage, so It could be used as /sdcard/ in CM10 so apps like Camera would work.
Thanks
Edit: Fixed English

Edit: Ok so I have worked out its /dev/block/mmcblk0p11 - cant format it ext4 then mount it using "mount -t ext4 /dev/block/mmcblk0p11 /emmc" but all the 'scheduled' tasks still think its vfat, so as a work around ill just format it as vfat.
This should be easy.... right?
busybox mkfs.vfat /dev/block/mmcblk0p11
Error:
mkfs.vfat: lseek: Value too large for defined data type
Ugh. Help me format this as vfat please

Fixed!:
Had to push a new version of busybox, which allowed vfat over 1gb.
Thanks me!

Change streak's innersd to 3 partitions,without disassembling phone,keep old data

Remember to fully backup your system first
do 1 -4 after streakmod 0.3.2.8
do 5 with newest mke2fs、e2fsck、busybox (or from the Attach Files )
1.mount data、sdcard
mkdir /datas
mount -t ext3 /dev/block/innersd0p6 /datas
mount -t vfat /dev/block/mmcblk1p1 /sdcard
2.backup
mkdir /sdcard/LOST.DIR/
tar -cpf /sdcard/LOST.DIR/data.tar /datas
3.del old partition ,add new partitions
umount /cache
umount /datas
fdisk /dev/block/innersd0

busybox mkfs.vfat /dev/block/innersd0p7
5.restore
mount -t ext3 /dev/block/innersd0p6 /datas
rm -r datas
tar -xpf /sdcard/LOST.DIR/data.tar

the Attach Files can change partitions automaticly
View attachment 2to3.zip could add new partition
View attachment 3to2.zip could change it back to 2 partitions
View attachment 3to3.zip is used to change the partition size
(change “+1G” in part.sh of the zip packages )
View attachment AutoMount.zip could mount the new partition after boot
in DSC 0.71, it will be mounted to /mnt/usbdisk ,the real u-disk will be mounted to /sdcard/usbdisk
in other systems,it will be mounted to /sdcard/usbdisk ,then you cann't umount your sdcard before umount /sdcard/usbdisk
After added new partition , you must not do Factory Restart or fastboot userdata.img , otherwise it will change the partitions back
so when you have flashed a new ROM or if you want to do factory restart ,you may need to fastboot my View attachment userdata.zip the other way is to do "wipe data /factory reset" and "selective restore View attachment firstboot.zip" by StreakMod 0.3.2.8
full restore by SreakMod is safe,it won't change partitions

What is the advantage of this? Also, there appears to be some formatting problem with your post, with some lines of single letters. Makes it really confusing looking.

Those are likely the commands to use fdisk itself. It's basically "what to press" so you could literally do it blind.
The innerSD is sometimes large enough to forgo using the outerSD completely, esp if you have a larger innerSD.
Given it's age, the S5 has an absolutely huge /data partition, it's nearly 2gb when comparable devices are 1gb tops (such as the venue)
Have you considered making your new partition and naming it /sdcard instead?
The correct way on HC and newer is to make /data/media a symlink to /sdcard and use MTP to mount it. The actual sdcard becomes /sdcard2
The S5 kernels do not support mtp so you cant do this.
But what if you took that new partition you made? innersd0p7 becomes /sdcard and the actual sdcard becomes /sdcard2. Then you could also use your partition for apps that refuse to work without an sdcard present (like titanium backup) Still you wouldnt be able to mount it.
The GNote does /sdcard/sdcard2 or something as a hack to support both without MTP, but it's hack and ultimately different from the standardized sdcard/sdcard2 in newer android.
ALso if you're repartitioning the innerSD, not only is a backup a good idea, but it's recommeneded to have access to the card itself. If for some reason the repartition goes wrong you might end up not being able to boot. Reformatting the sdcard externally will fix it.
OK, at first glance this line
fdisk /dev/block/innersd0

looked like it should have been fdisk /dev/block/innersd0p6
Like I said, first glance. Guess that is what I get for replying to posts this late at night....time for bed.

ext4 SD mount data not persistent across reboot

Hi,
Got this Desire Bravo with low internal memory so thought I should mount the app and data dirs to a ext4 partition on my SD card instead so I can install a lot of apps.
Followed this howto:
newton dot cx/~peter/2012/12/how-to-increase-app-space-with-a-partitioned-sd-card-on-an-htc-nexus-one-running-android-2-3-6-on-linux/
I found that my ext4 partition is mounted at boot time.
mount command gives the below:
/dev/block/mmcblk0p2 /mnt/sd-ext ext4 rw,nosuid,nodev,noatime,barrier=1,data=ordered 0 0
I can copy the data to the ext4 partition without any problem using "cp -rlp /data/app /mnt/sd-ext/data" and "cp -rlp /data/data /mnt/sd-ext/data" .
I can see the data when doing a "ls /mnt/sd-ext/" - looks ok.
But after reboot the data is just gone - just dont get it. Grateful for any help for troubleshooting this.
Running ROM CM10.1_VJ_4.2.2_V6.3_May24 .
Thanks...
EDIT: installed S2E app (Simple2Ext) instead, which didnt work well, so tried Mount2SD instead and appears to be working OK.

[Q] Link2SD:2nd partition shown but still not working

I tried to install Link2SD in Micromax A58 as the internal storage is very low and need to install some more apps. Already rooted and installed Link2SD to use the ext4 2nd partition of my 8 GB SD card. After trying with all possible ways, couldn't get it worked. All the time it was showing error--
"Mount Script can not be created. Mount: No such file or directory"
Previously even the 2nd partition was not shown as mounted in the storage info of Link2SD but after modifying the install-recovery.sh in /etc path, the storage info now atleast showing the 2nd partition as mounted. My install-recovery.sh looks like below--
#!/system/bin/sh
/system/xbin/daemonsu --auto-daemon &
/system/etc/install-recovery-2.sh
mount -t ext4 -o rw /dev/block/mmcblk0p2 /data/sdext2
mount -t ext4 -o rw /dev/block/vold/179:2 /data/sdext2
Now, the problems are as below--
1) Installed multiple applications but none of them are actually linked to SDcard. The Link2SD shows them as 'On SD Card' and just after installing 9-10 small applications, the internal memory is now full. If I go to 'Create Link', it is giving error '/data/sdext2 mount not found'.
2) When try to recreate mount script and choosing 'ext4' as parameter, it still throws error
"Mount Script can not be created. Mount: No such file or directory"
It seems that even though the storage info shows the 2nd partition as mounted, but system couldn't identify it somehow. So, Link2Sd is not working at all.
Please help and advice further. Thanks a lot.

can't mount 2nd partition after cm update

I have a 2nd ext4 partition on my sdcard that has apps installed on it. After doing a CM update, all those apps are missing and I can't recreate the mount scripts.
When I go into link2sd and try to recreate the mount scripts I get a dialog asking me to choose the filesystem with this path in it:
Code:
/dev/block/mmcblk1p2
I choose ext4, because that is the filesystem of my 2nd partition, and then I get an error:
Code:
mount:'/dev/block/vold/179:66'->'data/sdext2' no such file or directory
I've verified that /data/sdext2 exists. Any help or suggestions are greatly appreciated, thanks.

How to mount ext4 formatted MicroSD card on Android 6.0?

when click this message my microsdcard formatted fat32.
How to mount ext4 formatted MicroSD card on Android 6.0?
Thanks
So you need ext4 for symlinking purposes eh?
Anyway , if your device supports ext4 , depends on vendor , you can try to mount it manually
Root is required.
In adb ,
Code:
-adb shell
-su
-df
- cat /proc/partitions
when you know the partition for your external sd ,
Code:
mount -o bind "path to partition" /storage/sdcard1
If this works , you want to add this as a script to run at boot or create a init.d script by your own and give it 0755 permission.
Cheers
-Edit
If it didnt work , try this , it may be a little complicated

I need you to be particular with your wordings ..
Do you need ext4 sdcard to be mounted or exfat?
PS:
For File Size larger than 4gb , you can try NTFS , It is supported natively by my device.
Try formatting sdcard as NTFS and then insert into device.
If it shows any problem or doesnt mount , try this
Code:
-su
-ntfs-3g /dev/block/mmcblk1p1 /mnt/sdcard/external_sd
-vold
If this works , try making an init.d script with the above code , to mount sdcard everytime at boot
Cheers

It does not matter, I just want to support big size file 4g
I format ntfs but not work and type commands show error "
sush: ntfs-3g: not found"
I format ext4 too and test. command
# mount -o bind /dev/block/mmcblk1p1 /storage/sdcard1
and make director /storage/sdcard1 but show error"
mount: Not a directory"

I use terminal for commands
I guess due to marshmallow's strict policies , you are not being able to mount NTFS,
I will suggest you to format card as ext4 using EaseUS Partition Manager and then insert sdcard in your device.
Ext4 is natively supported by linux and I dont think it should cause you problems.
Cheers , Pressing that Thanks button wont harm you
I don't know lg k10 android 6.0 not support formats exfat,ntfs,ext4 for micro sdcard.
Does anyone else have a comment to fix the problem?
