[Q] How to mount partition 2 (ext3) on SD card?

[fuzzynco]

I used Amon-Ra's recovery to create a 1 GB ext3 partition on my SD card.
When I look at the card in a UNIX like OS the partition is there.

Ideally, I'd like to have partition's file system mount & unmount at /sd-ext
or /mnt/sd-ext programaticly. I've been trying to figure out what its /dev name is.

ADB's shell says partition 1 is /dev/block/vold/179:9 mounted on /mnt/sdcard.
There are 12 /dev/block/vold/179:?? (0-11) how do I find out which is
associated with partition 2?

Or is there another way to reach it? Is there a root app to mount / unmount
a file system? Do I need to use ADB or a local shell?

mouting and using tune2fs -l /dev/block/mmcblk0p2

tune2fs -l /dev/block/mmcblk0p2

you can use tune2fs -l and the block name to get the nitty gritty details of the partition or disk.

you can use df and or mount commands to get the details of your system

you can also cd into /dev/block/ and use ls to see all the files in there: below is my output with is use ls in /dev/block/

mmcblk0... is my external sd card, it has 3 partitions, mmcblk0p1 is the one recognized and mounted by android, mmcblk0p2 is the ext3fs, and mmcblk0p3 is a linuxswap file

This should mount the ext3 partition to /data/sd-ext. You will need to create the sd-ect folder before running the command in the terminal.

mount -t ext3 -o rw /dev/block/vold/179:10 /data/sd-ext

and than how to use it with vold to mount to PC via USB?

I dont believe that is possible, at least as far as i know. It would probably require a modified ramdisk which is over my head, i wouldnt know where to begin.
