SD/SDHC storage_test fails (system with eMMC)

[Erin Chen]

[Step]
1. Insert MMC/SD/SDHC card
2. Run Media card test

[Expected result]
test should be passed

[Actual result]
Test failed due to 'Not enough space', although there is enough space on the MMC/SD/SDHC card we inserted in step 1.
This system uses an internal eMMC storage partition (probably the recovery partition), plainbox will test all of the mmc partitions.
Attached is testing log and disk information.

Hi.

Could you please attach the output of "lsblk -O"

I tested the following on the device where the problem is encountered, with no external drive/memory cards connected to it:

/usr/lib/2013.com.canonical.certification:checkbox/bin$ sudo ./removable_storage_test -l --memorycard sdio usb scsi
--------------------
Removable devices currently mounted:
/dev/mmcblk0p3 : /
/dev/mmcblk0p1 : /boot/efi
Removable devices currently not mounted:
/dev/mmcblk0p2
--------------------

The `removable_storage_test` script sees the internal eMMC drive as a “removable device”.

The attached file is the output of the `udisks2_monitor` script from the same directory.

Ouput of `udevadm info --export-db`

Gabriel had a similar issue with a device that has an eMMC device:

Bruce Ma did some investigation, here is a copy of his comment in the previously mentioned issue:

This is a script issue. Because the script "removable_storage_test" checked all block device and compare the smallest free space with its request space, then raise the "Not enough space" error.

/boot/efi had 7 MB free space, but the script need 32MB(256MiB) space.

Found the following mounted sdio, usb, scsi partitions:
