/sdcard doesn't seem to be auto-mounted in b2g-gonk

cjones@scar:~/mozilla/firmware$ adb shell ls /sdcard cjones@scar:~/mozilla/firmware$ adb shell mount rootfs on / type rootfs (ro,relatime) tmpfs on /dev type tmpfs (rw,relatime,mode=111) devpts on /dev/pts type devpts (rw,relatime,mode=600) proc on /proc type proc (rw,relatime) sysfs on /sys type sysfs (rw,relatime) none on /acct type cgroup (rw,relatime,cpuacct) tmpfs on /mnt/asec type tmpfs (rw,relatime,mode=755,gid=1000) tmpfs on /mnt/obb type tmpfs (rw,relatime,mode=755,gid=1000) tmpfs on /mnt/usb type tmpfs (rw,relatime,mode=755,gid=1000) tmpfs on /app-cache type tmpfs (rw,relatime,size=7168k) none on /dev/cpuctl type cgroup (rw,relatime,cpu) /dev/block/mmcblk0p9 on /system type ext4 (ro,relatime,barrier=1,data=ordered) /dev/block/mmcblk0p7 on /cache type ext4 (rw,nosuid,nodev,noatime,barrier=1,data=ordered) /dev/block/mmcblk0p1 on /efs type ext4 (rw,nosuid,nodev,noatime,barrier=1,data=ordered) nil on /sys/kernel/debug type debugfs (rw,relatime) /dev/block/mmcblk0p10 on /data type ext4 (rw,nosuid,nodev,noatime,barrier=1,data=ordered,noauto_da_alloc,discard)

Not sure what's wrong. We obviously want to mount the sdcard partition.

1. internal sdcard mount failure: There are 12 partitions in mmcblk0, but vold defines MAX_PARTITIONS to 4 and mPendingPartMap types as uchar. With modifications to the two definitions, command vdc volume mount /mnt/sdcard can mount it successfully.

2. external sdcard mount failure: Destination folder /mnt/emmc does not exist. Do:

mkdir /mnt/emmc

chown system.system /mnt/emmc

chmod 000 /mnt/emmc

Then command vdc volume mount /mnt/emmc can mount it successfully.

3. There seems no one instructs vold to mount the two volumes. In original Android, these are done in java MountService.

@vicamo just getting the internal sdcard mounted is good enough for now. Let's worry about hot-swapping external storage later.

@vicamo I just gave you push access to the https://github.com/mozilla-b2g . You can fork system/vold under that account and apply your patch there.

@cgjones I've create another pull request #161 for this project. To be summarized,

• michaelwu/clockworkmod_galaxys2_initramfs/pull/2: merged by @michaelwu
• andreasgal/B2G/pull/161: waiting for review/verification

@michaelwu boot/clockworkmod_galaxys2_initramfs haven't got updated in B2G submodule since #f857321. Should I submit another pull request?

[michaelwu]

I'll update it.

[vicamo]

thank you :)

I have a pull request to fix sync error if it was meant to be current HEAD of cwm.
