user partition is not mounted on Linux

cgsong · Posted at 1/20/2015 10:21:43

I partitioned eMMC as follows. But Linux can't mount "user" partition and it mount the android "userdata" partition on Unbuntu. mmcblk0p15 device is android "userdata" partition. Please let me know what problem is.

userdata partition is Android's data partition, which is not mounted under Linux by default.

You can edit "/lib/udev/rules.d/80-udisks2.rules", and remove the following line:

# automount only user partition of Android
KERNEL=="mmcblk0p[0-9]*", SUBSYSTEMS=="mmc", ENV{PARTNAME}!="user", ENV{UDISKS_IGNORE}="1"

I removed that you said. After removing line in 80-udisks2.rules, linux mount many partitions. I think initrd is something wrong.

It is not wrong. It is the expected behaviour, mounting all the recongizable partition automactically.

Use something like this:

# automount only user/data partition of Android

KERNEL=="mmcblk0p[0-9]*", SUBSYSTEMS=="mmc", ENV{PARTNAME}=="cache|metadata|system", ENV{UDISKS_IGNORE}="1"

cgsong · Posted at 1/20/2015 18:02:33

It still doesn't mount user partition, mmcblk0p15 and mmcblk0p13 are android partition.

I'm frustrated. From your kernel log, this is your partition now:

userdata and user partitiions are both used by Android. userdata is mounted on /data,

and user partition is mounted as internal storage.

Now that both userdata (/dev/mmcblk0p13) and user (/dev/mmcblk0p15) parittions are mounted.

What would you like to archieve?

I thought the user partition is used for linux, but you said user and userdata partitions are used for Andorid. I'd like to know user partition purpose.
