Android-x86-6.0-rc1 how mount another PC partition?

[Krister Hallergard]

Before I have been able to add "SDCARD=/dev/sda" or  "SDCARD=/dev/sda1" to the kernel command line to mount a partition wher I keep data, office and multimedia files. Have not managed to do that with Android-x86-6.0-rc1, please advice! http://goo.gl/EpSOi0

No, this method is not supported in 6.0.

The reason is Google has rewritten the whole
vold, the volume daemon (ver jumps from 2.1 to 3.0).
It has implemented most of the auto-mount functions
that we did in the previous 2.1 version except
the SDCARD method. Basically speaking,
the SDCARD method is just a old hacking so that
I think it should be deprecated.
Currently I have no plan to add it back to vold 3.0.

The only workaround is to add the sys path of
your sda to fstab.android_x86.
But that means you need to modify the ramdisk.img.

follow those instructions . it is working in android 6

read and write，mount as label，why do not you use stickmount ?

Thank you for the clarification, though disappointing.  Am looking for a simple way to mount another partition on the PC, and the suggested alternatives seem all but simple.

[Chih-Wei Huang]

Actually you don't need an additional tool to
mount an NTFS partition.
Android-x86 has the built-in ntfs-3g tool
which can do it:

ntfs-3g /dev/block/sdX /storage/D

[Krister Hallergard]

Could you please give a step by step instruction.  Terminal? Permissions? Mount points? Script? etc

[Hypo Turtle]

He already did:

ntfs-3g /dev/block/sdX /storage/D

With X being the partition number (check with blkid if your unsure on number); and D being the mount location.

You may need 'su' first and alsi 'mkdir /storage/D'

[youling 257]

So，why aosp 6.0.1 can't use Storage&USB portable storage mount NTFS partition ? 

This is Android，I suggest use Android apk or Storage&USB portable storage，I don't suggest use Terminal Command or boot script. 

why cm13 can use Storage&USB portable storage mount NTFS partition ?

these screenshot，it's cm13

[Hypo Turtle]

If I'm understanding your question right then...

Because Ax86 is AOSP (or as close to as possible) and CM(13) is a custom ROM/firmware based on AOSP that modifies system source (framework/settings etc.) in order to add features.

CM13 would probably mount NTFS the same way (ntfs-3g); just that it has a button that does it for you. Or it could be something modified in vold.

[youling 257]

cm13 use mount.ntfs，and fatab.android_x86

The volume daemon of AOSP doesn't support NTFS.
CM has modified the vold to detect and mount
NTFS and exFat automatically.
Surely we can leverage the code from CM.
(actually we did that in kitkat-x86 before)
But it's not a high priority task so
no dev cares to do it

[Krister Hallergard]

In a terminal I applied these three lines:

     su

     mkdir /storage/sdb4

     ntfs-3g /dev/block/sdb4 /storage/sdb4

Started ES File Explorer, and allowed SuperUser

Made a ES Widget on the homescreen by navigating to and selecting the sdb4 folder in /storage, yes there I could no see all folders and files on my main windows 10 partition.  Tried to play some videos, no would not play with any player.  My impression is that I need to change some permissions or something.  So I have two question:

1.  Do I need to change permissions?

2.  How do I avoid having to redo everything at each boot??

If I made a script with the three lines above - where do I put it to autostart it at boot time?  There is this script /etc/init.d/init.sh, but how to enter these lines lines?

[Arun G]

did you turned off windows fast boot ?

Yes, have disabled hybernate

Turn off fast startup . disabling hibernation is unnecessary

I have always had hibernation disabled on Windows 10, as it stops me from mounting the Windows partition from Linux.  I thought that fast boot automatically was switched off when hibernation is disabled. Android-x86-6.0-rc1 is on its own separate partition.  It can mount the Windows partition okay, but it seems to be in read only mode.

How make a script to autostart at boot with   "mkdir /storage/sdb4"   and    "ntfs-3g  /dev/block/sdb4  /storage/sdb4" ?

   How change permissions so that I can access any file on on /storage/sdb4 ? 

[youling 257]

nice，nice ! Android x86 6.0.1 r52，nightly version，can mount NTFS and ext4 partition.

Hello my friend. I'm using Sticky Mount app from Google Play by Chainfire. It will automatically mount the windows partitions on boot and then you can go and access then thru any explorer drive. IT works on vanila ANdroid X86 but not on Remix OS due root issue with remix os. Navigate to any file explorer app and find sdcard/usbstorage/ they will be there

Hi Mario, this is great news! With Sticky Mount I can now mount all my ntfs and fat32 partitions on the same PC (but not the ext3 partitions - but ext4 probably also work). Thank you very much!

Did it on the running system with (a) remounting / rw (b) adding .../*/ata*/* to the fstab (c) killall vold

> But that means you need to modify the ramdisk.img.

If Ax86 had init.d then it shouldn't be necessary.

Then how hard that would be to add other FSs, like ext3/4 and btrfs? Kernel already has them all, the vold left..

Best regards, Ildar.

[Chih-Wei Huang]

I've added back the SDCARD= function to the 6.0-rc2.
I think it's still useful to some people like you.
You may use "SDCARD=sda"
(auto select a partition on the first drive)
or "SDCARD=sda3"
(mount the third partition on the first drive)
to the kernel cmdline.

[Krister Hallergard]

Thank you, that will be useful!

I edit CONFIG_F2FS_FS=y，recompile kernel，install Android x86 on f2fs partition ；Vold 3.0 (the awakening) firing up，Detected support for: exfat ext4 f2fs ntfs vfat；

But Storage&USB can't mount f2fs partition，because blkid can't read f2fs partition's label，The platform uses blkid to detect filesystem types before mounting, and users can choose to format the media when the filesystem is unsupported.https://source.android.com/devices/storage/config.html

Why?
From the list you posted f2fs is detected correctly.
Isn't it?

blkid read the label is important.

I notice https://sourceforge.net/p/android-x86/bootable_newinstaller/ci/marshmallow-x86/tree/initrd/bin/busybox ' blkid can read f2fs partition label and type，at debug mode，mount -o bind /sbin/blkid /android/system/bin/blkid，then  Storage&USB can read f2fs partition label，but still corrupted ；the Android-x86 corrupted is normal，the SDCARD1 corrupted mean is can't mount f2fs partition.

The comand ntfs-3G in latest Nougat lineage do not work, it was removed?

I suggest you use busybox 1.28.1 blkid，rename busybox to blkid，or /system/bin/blkid link to busybox 1.28.1
the blkid is important for Storage&USB portable storage.
